| 00:01 | Okay. No. Okay. So , I will start to talk about |
|
| 00:19 | next programming paradigm, N B This is a chart. Uh the |
|
| 00:28 | kid background two. Well yet another paradigm and then talk uh that's Generally |
|
| 00:43 | today. About 10 PI get some picture stuff. Next time. Talk |
|
| 00:48 | specifics. So um first about clusters what's also known as m p p |
|
| 01:00 | that stands for massively parallel processors of the current there aren't that many around |
|
| 01:06 | goes in waves come and go um point out what the different differences are |
|
| 01:14 | those. But as a part of guess graduate education, which you also |
|
| 01:20 | what employees are. All right. clusters you already use clusters in this |
|
| 01:30 | mostly have used single notes on clusters not. So in that case there's |
|
| 01:36 | difference whether the notice in the cluster just stand there don't think. Um |
|
| 01:46 | the cluster is best to have a your by yourself collection of servers or |
|
| 01:55 | and you will come up by network then you and to call it the |
|
| 01:59 | . And I thought more about specifics clusters I think on the very first |
|
| 02:05 | second lecture, talking about slow rem fastest poster has notes that are at |
|
| 02:15 | the same same type of seed to but sometimes also that's different. The |
|
| 02:20 | difference among the notes and the prostitutes be that that they have different demands |
|
| 02:26 | memory on the notes. However, accelerated from some of the notes such |
|
| 02:30 | depressed for the british customs, you regular members, large memory. Extra |
|
| 02:38 | memory or sense either it's the fourth non jobs. More of this giant |
|
| 02:44 | then there are the deep, you um so I didn't put the picture |
|
| 02:49 | then there is a Also at least typically known as front end. No |
|
| 02:56 | this so on that access the cluster , throw it then the other special |
|
| 03:04 | sizes for cluster management things. But a user you basically see the front |
|
| 03:10 | you log in and transfer your codes it and manager execution from that. |
|
| 03:18 | talk a little bit about how things then connected so and so on and |
|
| 03:28 | otherwise, you know, I'll show some pictures and clusters and semen ever |
|
| 03:33 | just you know, be an abstract the net. Then there's a massively |
|
| 03:37 | processors and GPS and they tend to , they have a more highly integrated |
|
| 03:43 | and talk about the difference for that it says that the differences that that |
|
| 03:51 | to be engineered more for low I invent nothing to connect and the |
|
| 03:57 | of the single system as opposed to systems roman program and I said tested |
|
| 04:06 | the same note. So that's pictures clusters all kinds of flavors. Early |
|
| 04:14 | uh you know, build itself that are one more professionally put together clusters |
|
| 04:21 | some deep uh bridges and somehow they and it's just not a little bit |
|
| 04:28 | detail of things. So yes, their networks between the notes on your |
|
| 04:35 | switches and cables of all kinds of tables or fiber tables that connects between |
|
| 04:44 | and switches to build the network of clusters and sometimes there are put together |
|
| 04:52 | this one that happens to be an but they can look from the north |
|
| 04:57 | the outside but it is inside. it's just an example of finally most |
|
| 05:07 | empathy is that in this case is audience blue team computer system from another |
|
| 05:14 | . General questions and clusters. Yeah. I am just so far |
|
| 05:22 | me connection. You know the not internet. Maybe I'll talk about |
|
| 05:29 | But that's one if it's if the is not the capabilities of the internet |
|
| 05:37 | not all that critical then because the that because of expense, it is |
|
| 05:43 | flipping is something that we have updated . The connections like that rescue |
|
| 05:51 | All right, terrible. So which you know higher bandwidth? Right. |
|
| 06:05 | but they don't use the internet for internet of internet taxi. Oh, |
|
| 06:13 | why don't you use USB type 00. I say yes. That's |
|
| 06:17 | oh, USB type C. First bandit is about less than what is |
|
| 06:25 | typically in clusters and also the licenses fancy and you came back and |
|
| 06:36 | So what's used as I said, on what is needed for the system |
|
| 06:48 | such targets than you think, you maybe because uh I don't under they |
|
| 06:58 | to be apparently unwilling to spend money to connect. So you speak of |
|
| 07:05 | in there sometimes and it is changing bit terms of busters that is used |
|
| 07:14 | many scientific applications were interconnected. It's they use 100 because it's higher and |
|
| 07:22 | that the use of some comments on protocols and also I remember that discussion |
|
| 07:31 | processors, they have a bunch of lane's that reason to hide the area |
|
| 07:42 | tend to have more than one or of the speed force. So I |
|
| 07:47 | the process of side or in the other boss do not have any of |
|
| 07:52 | closest and capability of movement because you compared to figure to teach in there |
|
| 07:58 | something else. Oh yeah, You're kidding. Right. So that's |
|
| 08:11 | good question. So I talked to first comment a little bit more only |
|
| 08:18 | . So the other part, since talked about um, you know, |
|
| 08:23 | and programming. So in terms of single notes and look they notes would |
|
| 08:31 | using it like kind of up to 96 3rd maximum I think we have |
|
| 08:37 | example 48 Cores and two or 4 that I quit reading. So it's |
|
| 08:44 | to about 100 threats in the note when it comes to castries and several |
|
| 08:52 | of magnitude potentially board. So scalability strengths is very important. So I |
|
| 08:58 | give a perspective, zone area is of course, and typically, you |
|
| 09:04 | , as we know Courses, one 2 threads in some cases four threads |
|
| 09:08 | core possible. Uh It's just like months before that's actually more. But |
|
| 09:18 | in terms of number of third some small factory depending upon was living |
|
| 09:26 | , but the president is enabled but in this case, so this is |
|
| 09:32 | the horizontal, so access time and goes until The last 500 list uh |
|
| 09:40 | Tom June last year there are a of weeks, But as you can |
|
| 09:49 | it's up to 100,000 plus scores. compared to about 100 threads, this |
|
| 09:56 | considerably higher question, scalability is very , of course, Top 500 system |
|
| 10:05 | kind of large systems compared to your systems, but I'll come back to |
|
| 10:09 | too. And this is sort of maximum number, of Course insistence uh |
|
| 10:17 | is up to about 10 million So it's uh and even as if |
|
| 10:24 | look at the lower end of the , so the number of minimum number |
|
| 10:30 | that end up on the list is in the water. Thousands, of |
|
| 10:35 | . Yeah, down here is another of ceo look at science, it's |
|
| 10:46 | both enough then the bar them from . This uh huh of course, |
|
| 10:55 | the bottom map. Yeah, of . So we have this capability is |
|
| 11:03 | important and I didn't have a sorting since most of you probably going to |
|
| 11:11 | industry as it is a large share the distance on this top priority limericks |
|
| 11:24 | even though they're citizens center, the the collective performance of their system a |
|
| 11:32 | bit more than the quarter of the number of systems is more than |
|
| 11:39 | Yes. Yes. It's a So this is a gun summarizing whatever |
|
| 11:47 | said, this is scalability is a deal in terms of uh, the |
|
| 11:56 | and algorithms, clusters in general. next is a little bit on listening |
|
| 12:05 | connect and what makes the difference between these clusters in the society, the |
|
| 12:12 | of integration. Uh, and I sent to comprehensive systems. It tends |
|
| 12:19 | be that the empathy. He's the the connection between those are kind of |
|
| 12:26 | the level of Level three Cache is that means whether it's remote now remote |
|
| 12:33 | almost as goes to the functional units a test was to typical courses in |
|
| 12:43 | ways. A few times they used bust the PcR basis to connect and |
|
| 12:51 | a picture at all and one of and that is the idea of a |
|
| 12:56 | that I mentioned and it just shows in this case an approach into |
|
| 13:02 | Thank you a lot of food. . I mean into the system in |
|
| 13:12 | to get very low latency connection between and no, I was and also |
|
| 13:18 | bandits that's proprietor interconnection And it's something . Time forever. Interconnect technology as |
|
| 13:28 | and otherwise. And the cost of . The system mentioned a few times |
|
| 13:34 | used the PC express bus and the started circuit court to put things up |
|
| 13:46 | mm hmm. Yeah, it's Yeah. So, um, |
|
| 13:54 | That's not really talked about the terminal . Was the standards uh dr $400 |
|
| 14:04 | use connections. Close distance. Uh, is there a 59 overhead |
|
| 14:15 | can see So if things are in effort. Oh, his critical |
|
| 14:24 | those systems that you see them in van or I believe the finances. |
|
| 14:33 | , it's simple enough to are you mhm. Think about so revolution. |
|
| 14:45 | processor obviously they want to get a coarse and capability 17 years. And |
|
| 14:55 | , this is a correspondent and particularly also, oh, The technology for |
|
| 15:03 | happening about every three years in terms both even. Uh mhm. So |
|
| 15:13 | don't drive too compete in the african . But it's something people in the |
|
| 15:21 | that unfortunate about this incomparable power. no. So is that enough for |
|
| 15:30 | ? Opposition? Yeah. Um, put that one. What is the |
|
| 15:37 | access inside coming off screenshot produced design . The song. Great computer company |
|
| 15:49 | is our speak require says to Um and I think I will talk |
|
| 15:57 | that a little bit today. But . So, so everybody. So |
|
| 16:10 | relationship of economics is so what happens etcetera, put it on the car |
|
| 16:16 | a second friend words. Yeah, been about 32 soldiers. Uh, |
|
| 16:24 | the, you know, the two points. That's the reason why it |
|
| 16:33 | , these technologies exist and systems where communication is important for the moments. |
|
| 16:44 | . So Yes, a question or . Yeah. So from the biggest |
|
| 16:53 | we have a different types of media to help pay for he's gonna |
|
| 17:00 | So opening the neck, those we'd there for you. I can |
|
| 17:07 | All right. Oh, how to it away. Yeah. Economic disputes |
|
| 17:14 | these wireless technology. Oh yeah. , uh, okay. The number |
|
| 17:26 | white pine and make the standard, fun. A couple of 100 megabits |
|
| 17:30 | second. A Big Boy 5, brakes, one number of minutes under |
|
| 17:43 | . I'm nine Point says become pick this person, you know me. |
|
| 17:50 | , for my question. Okay. it's still over and then in order |
|
| 17:58 | thousands onion soup and it's the, say I'm sure is cold outside. |
|
| 18:16 | , and also so weird to think having, I don't know, were |
|
| 18:26 | still hold experience your entire, you know, it's going to have |
|
| 18:34 | little radio in your back pocket, device you have and it's also an |
|
| 18:39 | point and the access point usually cannot . All right, more than ever |
|
| 18:47 | started yet. I'm just, so this case The northern clusters here than |
|
| 18:56 | are 10,000 or or out. It about 10,000 people working to elect a |
|
| 19:02 | access point that would it doesn't have take the willing to dealing with each |
|
| 19:09 | because it's the taxes come from what doesn't help to dozens connection at the |
|
| 19:19 | time. Got it. Traffic Yeah. Yes, yes. So |
|
| 19:38 | also say seven at books also growth you have lots of people and they |
|
| 19:45 | for the area part of the Yeah. Our oh so led by |
|
| 19:56 | of us are used to in terms customs. Uh Yes. Uh yeah |
|
| 20:10 | so on. Oh some are a bit okay dr months old. The |
|
| 20:19 | on the strength of nine communicating with other sometimes or Yeah, that's a |
|
| 20:31 | processor and so on. Pretty much proprietary technologies can use. So, |
|
| 20:39 | know, foreign policy figures should not anybody else. Oh, in with |
|
| 20:47 | . Uh huh. If you don't too many force on the ring. |
|
| 20:55 | . No it's not Okay. But from my report, you know, |
|
| 21:05 | or avoid congestion by uh this piece so that's the National forest. No |
|
| 21:13 | . Right? Their craft just so that's what this car they got the |
|
| 21:20 | into connect awesome example. Uh huh then one between office first report, |
|
| 21:35 | also a dominant prior to connect. processors uh huh acknowledges it's the family |
|
| 21:49 | of mask into the Yeah, our protocol. Not respectable as onto effort |
|
| 22:01 | Okay. So I love that. , it's press button, are you |
|
| 22:07 | it? Yeah, that's on it possible systems to books implement so. |
|
| 22:21 | hmm. And then when it comes you as compensation knows no system just |
|
| 22:29 | from the net for you. Did . Uh huh. Citizens desire for |
|
| 22:38 | efficient computation. Our technologies and All right. Also because it's the |
|
| 22:52 | and they tend to use the diese or sometimes they will send a special |
|
| 23:00 | , african or question the faces from processors. So it's again the processors |
|
| 23:08 | about the particularly taking into them and their support. He said express |
|
| 23:16 | internet protocols and uh, also some protocols must follow uh, intercity traffic |
|
| 23:26 | management and other things. So we find a bunch of wires and go |
|
| 23:30 | and look at the sky lake. will see the collection of they said |
|
| 23:35 | transport and nuclear courts 45 to communicate different ways. Either with other sockets |
|
| 23:46 | but other notes. So, this kind of the picture again, that |
|
| 23:55 | a bunch of notes that are independent effective their own memories and processes and |
|
| 24:03 | they put into some networks typically the it's quite simple basis. So any |
|
| 24:13 | questions on that. Okay. All . So the new thing in terms |
|
| 24:22 | technology that we have talked about was works At that .6 but functionally there |
|
| 24:32 | now also data communication. What does system memory or access to accelerator sentinel |
|
| 24:41 | . So what I'll talk a little about one's characteristics that from performance point |
|
| 24:48 | view. So um, so this of vacancy and that comes back memories |
|
| 24:59 | that. It's also expected no conversation system. Uh, someone is still |
|
| 25:11 | put together some message some way or information to the receiver. Yeah, |
|
| 25:20 | difficult required some work. Yeah. the time different parts of the desiccated |
|
| 25:29 | are the consequence two put together heather said something about sending the there's a |
|
| 25:39 | that requires sometimes transporting similarly anywhere that want to do and that's sort of |
|
| 25:51 | message. So there's a big confusion being used there system stops off the |
|
| 26:03 | being effect ability over huh. So we start and they stop and |
|
| 26:12 | these were delayed for the whole transaction the fact that the table yeah actions |
|
| 26:23 | change the whole time or delay for communication transactions is the different areas to |
|
| 26:33 | the latency as opposed the reason for rest of trust mission. So as |
|
| 26:41 | said sometimes when you read papers or a treat pregnancy as the whole time |
|
| 26:49 | supposed to Thanks related to overhead. this is just kind of find them |
|
| 26:58 | show. Mm hmm. The fact all different basis is uh, to |
|
| 27:06 | around with the numbers and the So what uh the vacancy is something |
|
| 27:17 | an independent of the table sites of bike uh detective agency. Large |
|
| 27:26 | It was like a city uh huh of science for the payload size pieces |
|
| 27:36 | are kept. Yes. Crichton illustrates trainers. Yeah separate so difficult and |
|
| 27:50 | fact that made our first arrival vacancy save us. Oh uh and I |
|
| 28:01 | to see the doctor the cradle needs be to get ready comfortable to the |
|
| 28:08 | data. Okay station so the assignment has to do then for NPR should |
|
| 28:19 | be asked positive fight identified agency and again communication so this um so uh |
|
| 28:37 | is uh what when you're trying to of like you have an understanding of |
|
| 28:44 | goes on one also to mention a times in terms of the congestion that's |
|
| 28:53 | . And that defense clearly are what computation task is and that's what busses |
|
| 29:02 | are no longer used generally because you , perhaps things get congested very quickly |
|
| 29:11 | . That's true. Did announce very for instance. Mhm The reason is |
|
| 29:19 | it's kind of also limited uh in of what handle so that when the |
|
| 29:27 | count today what is being used on silicon processor is the best technology connectivity |
|
| 29:37 | it comes to clusters that even The d. mash is not used very |
|
| 29:44 | anymore because the number of those are high Even a two d mass to |
|
| 29:49 | this enough conversation capability to and the from all the notes sold, you |
|
| 29:57 | , higher dimensional Manchester's for what snow wrapped around him to connect them out |
|
| 30:03 | door. A tourist or a little And they have five or 6 |
|
| 30:10 | You're right. We become in order have something that has enough communication technical |
|
| 30:18 | many applications um and then it's all or is a driving protocol. So |
|
| 30:29 | and for sandals this course also or effort and opportunity for holidays protocols for |
|
| 30:38 | to be with the rising this effort the modern networks also message priority. |
|
| 30:51 | uh huh other features that yes, retaliation but after rioting and many different |
|
| 31:07 | are happening and today's networks so they by normal central So any questions on |
|
| 31:19 | general aspects. So I want your . I have a few slides here |
|
| 31:28 | fix it very quickly and it's uh or less just for you too. |
|
| 31:37 | attention when you read papers as opposed um I took the tracks but the |
|
| 31:45 | not what to read. So I these were kind of became uh so |
|
| 31:54 | the competition after it. So And what is the number one center |
|
| 32:01 | the liver type of to connect That's absurd. I'm trying to make |
|
| 32:09 | that he by their own the fact connect or a bunch of papers showing |
|
| 32:20 | . All right. No presentations of Avengers inside visual. They're always the |
|
| 32:26 | . And compared to the other guys is a little bit of the difference |
|
| 32:33 | aggressiveness of position themselves. Uh huh Compared to the competition. So |
|
| 32:42 | So in this case uh in terms mental notes when they compare themselves to |
|
| 32:50 | internet to connect knowledge always win uh or less and uh on the other |
|
| 32:59 | uh intel waters on the right hand but then the events Parks admitted that |
|
| 33:06 | were not always the best. Uh and then is so there's a bunch |
|
| 33:13 | size writing. Okay. You curious more than anything you need to |
|
| 33:20 | far class but you can see how different ones and they are. They |
|
| 33:26 | themselves and in this case I was impressed by into making, you |
|
| 33:33 | we don't always win something this configuration but and they are not sent to |
|
| 33:39 | we're all this best buy significant This is a little bit here. |
|
| 33:45 | of this somewhere is lining the blue is the this is us and a |
|
| 33:51 | and look at what the guy So I know, I know, |
|
| 33:57 | maybe his sister cautionary tale fun how interpret what to see that And a |
|
| 34:05 | of comments on this slingshot technology that is as you see the amount of |
|
| 34:14 | and it's being used the largest the latest and largest acquisitions department of |
|
| 34:23 | for the higher systems that this interconnect . Yeah. Um here's a comparison |
|
| 34:32 | with this being compared to Uh So they specifically for that. |
|
| 34:43 | and it's not me. It's the if I'd be correspondent. It's about |
|
| 34:51 | quality. Yeah. It's already shows comparable rather than as much but it's |
|
| 35:01 | some technology positive. Just control the . So seven has been the |
|
| 35:10 | Yeah. This big that position. uh I guess so. I showed |
|
| 35:18 | effect of this congestion control that and , I'm not going to care |
|
| 35:25 | So you basically about whenever the country's with something that is also an |
|
| 35:34 | uh until we're done. So it's johnson. Mhm. All right. |
|
| 35:47 | their questions on that. I'm not to talk more about network today. |
|
| 35:57 | . So now I talked about NPR , so what is behind this message |
|
| 36:09 | interface? So yeah, it's conversation library thing and the underlying things |
|
| 36:18 | definitely like the open and see it done well put together based on the |
|
| 36:25 | hardware characteristics. It was open. to see whether it's american spaces, |
|
| 36:32 | instruction sets and trying to figure out to manage all of that for us |
|
| 36:37 | succeed. Uh, notion of independent hooked together over a network. The |
|
| 36:47 | for africa. So, but what means is that it's about the independent |
|
| 36:56 | . General, there is no notion global address space. So each computer |
|
| 37:05 | its own uh that's it and that stuck. It was all in the |
|
| 37:14 | losing a bunch of pills and buster maybe that is it's up to the |
|
| 37:22 | to figure out. And it's a our power to yeah, variable updates |
|
| 37:31 | sharing data between the notes in any . And you're absolutely right right. |
|
| 37:40 | language of the compartments and so the main difference compared to for instance open |
|
| 37:49 | Yes. Mentioned this in the program also on this place every now getting |
|
| 37:54 | program quick say uh probably uh There's something you're welcome to write |
|
| 38:02 | Unique culture installed problems, particularly people 50. Okay, excuse the single |
|
| 38:10 | and replicated across the notes in order get some time. It's very much |
|
| 38:28 | . So then sent to the bottom this I say yes. People they're |
|
| 38:32 | to But in the case of all the genesis program. And we talked |
|
| 38:40 | even if my memory. So in to simplify programming from trying to create |
|
| 38:46 | illusion of it single address space uh then provide mechanisms for it that the |
|
| 38:53 | of what you need to and what in fact, so you can comment |
|
| 38:59 | that from somewhere exercise right? I to Vietnam or later. And that's |
|
| 39:07 | because of the frameworks that's mentioned here the slide of figures. Yeah. |
|
| 39:15 | it as part of life. All . We're basically trying to collect baker |
|
| 39:23 | . Uh huh. On the programmer so that we can use our |
|
| 39:29 | But as knowledge the responsible one. . And then you don't have to |
|
| 39:36 | about it does the anti battles even the internal Biggest movements but presents the |
|
| 39:44 | after space. Is just one verify was based on the ground. |
|
| 39:51 | The product mainly involved simplifying the programming coming from almost without losing too much |
|
| 40:04 | . Yeah. Because if you try make things abstract performances Compare it to |
|
| 40:12 | using five numbers of seats. I give you program and believe it or |
|
| 40:17 | the money back. Too much performance the similarities. Yeah. So in |
|
| 40:24 | case, well this part this can as further. Just the basic notion |
|
| 40:34 | the programmer has this seeing what uh the work for their financials in order |
|
| 40:40 | get told job to. So The independent. And this takes a |
|
| 40:52 | level. Program is nose and accept process. Not this president doesn't tattoos |
|
| 41:03 | FBI. But just keep it simple the moment. Uh processes by whatever |
|
| 41:11 | a. I'm sort of fit the that is between processes the apartment |
|
| 41:23 | It notes the processes can be on same note that it's not impossible or |
|
| 41:32 | run an FBI probe the fact that proper speed. Yeah. If we |
|
| 41:43 | hadn't using communication. Right. Interaction the wow, right. And this |
|
| 41:59 | just a reminder of the difference in of processes versus thread and that is |
|
| 42:05 | . I think processes. I dismissed state associated. Um And this is |
|
| 42:13 | one of the side that it's up the program and to figure out and |
|
| 42:19 | for the district notes. So it's , in terms of open empty it's |
|
| 42:26 | global address pesos later is a fun . Open. H you see, |
|
| 42:31 | was a little bit more work because are two different memory spaces and the |
|
| 42:36 | . What sort of device? Um us an FBI that there is now |
|
| 42:45 | no on family space at least you know, if you have an |
|
| 42:51 | processor in front of the nose and are additional complications the member spaces of |
|
| 42:57 | touch processor and almost no medications. a lot of the things I'll talk |
|
| 43:05 | more in detail next time as the went the communication part. Yes. |
|
| 43:12 | example for within the cluster between notes we'll join the examples next time. |
|
| 43:23 | that's like uh huh. The most example there was this a good |
|
| 43:32 | So you're stuck with last time was . To do you think you can |
|
| 43:38 | of is really dark? Uh something needs couple then they would do all |
|
| 43:47 | us suffer spread. But at the I wish this former example of the |
|
| 43:54 | you can have a time and he's of the notes and under the city |
|
| 43:59 | department times. I don't know. haven't created in different notes. I |
|
| 44:06 | give you a concrete examples. so conserve it's very flexible. So |
|
| 44:18 | also thinks the holidays or something known the clock ticks operating system that we're |
|
| 44:24 | in essence passing operating system where different sends messages to coordinate the work between |
|
| 44:31 | other. So it's incredibly flexible model it's also not jbl to implement this |
|
| 44:40 | here so that's fine. Libraries exist yeah, Up to six awhile to |
|
| 44:50 | , this offer to be efficient because complicated and it also depends on the |
|
| 44:56 | hardware hardly implement this. Uh And here is just a very simple principle |
|
| 45:06 | message passing that I want to sure doesn't happen. Another note, the |
|
| 45:14 | are and uh the basic thing is order for the things up to get |
|
| 45:21 | . So I kind of got to out if they're ready to receive |
|
| 45:26 | Sorry, dissipates and something and then get all the expenses TCP protocol, |
|
| 45:34 | kind of a handshake to request to something. Actually just okay. Search |
|
| 45:44 | actually between receiver in order for So that's it on the night and |
|
| 45:53 | see that next time. What about fact. Right. And other forms |
|
| 46:02 | communication. And so kind of the someone's IT uh business FBI certainly system |
|
| 46:22 | model versions have seen porter uh help I think I think there are there |
|
| 46:33 | I have not built into something because not something that you see because uh |
|
| 46:44 | . The version four. Mm. yes yes. Just like with open |
|
| 46:58 | be, can open it to see point of M. P. |
|
| 47:03 | Is for the program and to be to write you affordable codes, |
|
| 47:11 | You know you can use CUda accelerator that's not filled with people do that |
|
| 47:23 | they have their own one level of or progress specific stuff and the purpose |
|
| 47:32 | small you have to in this case only do you not currently in the |
|
| 47:39 | important but they're not about technology. to figure out the scent energy |
|
| 47:46 | Mhm. Um uh second. So tried to get a bunch of |
|
| 47:58 | Uh the same communication. Sure. . Uh A place it shouldn't |
|
| 48:09 | Uh huh. They're not. And this notion of collective communication so that |
|
| 48:20 | . Okay there's a bunch of processes engaged. The action one centre that |
|
| 48:27 | and I'm up for the receivers so connected complication. Is that the one |
|
| 48:34 | talks about different shapes and forms this . So if they have there's been |
|
| 48:42 | things up across from results from additional . That's another type of bullet |
|
| 48:50 | NPR's support. Yeah. Um And also certain you can define data |
|
| 49:01 | . Uh I think concern open and define your own data. There is |
|
| 49:13 | . Okay. Change to different types more against complex applications. Various Sudan |
|
| 49:19 | so defining it on data types. so here's superintendents references to where they |
|
| 49:28 | there's tons of things. There were uh editorials decision papers from. So |
|
| 49:39 | the basement. So there's no shortage of information about about the FBI. |
|
| 49:47 | there is another forum the clients often so they they support performance. What |
|
| 50:00 | goes on five. Right? Yes am. Yeah. So well conscious |
|
| 50:14 | of the time that it cooks for external programs accept information. But uh |
|
| 50:28 | I think that I don't remember any . Change the communities themselves. Certain |
|
| 50:39 | . Mhm. But normally they would some of this on a towel. |
|
| 50:47 | that is linked to NPR numbers. step. So I get to |
|
| 50:56 | Oh, so or in except for for instance you may. Yes. |
|
| 51:08 | data from some FBI uh in terms analyzed the problem however, take a |
|
| 51:18 | of enough. Whereas the town and are the tools waste of extracting useful |
|
| 51:25 | from several months. So that's the why we are that you use the |
|
| 51:35 | because of animals that once a Yeah. Itself it was broken up |
|
| 51:52 | it's like, you know, something on the doctor about party party to |
|
| 51:55 | to that counters. It doesn't mean can't trying to get the content information |
|
| 52:02 | . It comes in the form. is not a comprehensive. Yeah. |
|
| 52:18 | . All right. So this is little bit you know what address this |
|
| 52:27 | on the point and nancy. If sequential program, it's good enough for |
|
| 52:36 | that you want. There's no point to make it complicated. Classical |
|
| 52:43 | saying things you can do the And I think I know there's no |
|
| 52:49 | scientific african notes recently. And that's there's and we also have an open |
|
| 52:59 | this example that just because of the creating regions in that taste and |
|
| 53:05 | well, there's a number of situations . Next. Just two singles that |
|
| 53:10 | talk to Carlos. It was And if this case yes, generate |
|
| 53:16 | friend's father was stopped. It's the thing. Always conscientious of how much |
|
| 53:22 | there is. And it's always better try to optimize its internal code and |
|
| 53:26 | to paralyze. It's pretty much the home message and this is the |
|
| 53:35 | This is still alive and well in of new Russians understanding the pretty much |
|
| 53:43 | the time and then part of it to increase functionality. Um, and |
|
| 53:51 | fact it is to adapt things to evolving hardware on this is being used |
|
| 53:58 | running. But it also said that the basic ends up in violence. |
|
| 54:07 | burning any form of suffering these three fire under this after. Right. |
|
| 54:18 | . You can do go little bit . 16 that area on stage of |
|
| 54:28 | so a little bit more about mm . Control. But essentially what the |
|
| 54:41 | Okay. Region in the past. ? So I was just closing |
|
| 54:52 | All right. Uh, they You're welcome. No problem. Oh |
|
| 55:04 | our ball. Uh huh. I think that frank is uh trade |
|
| 55:18 | open empty so whether Yeah and then obvious but how they work is not |
|
| 55:31 | mm Any comments from the international service . Okay. So this is a |
|
| 55:43 | time. So uh and the other to do so again not to use |
|
| 55:54 | level. This is fun a communication for the chief and have in the |
|
| 56:02 | of the paris protocol. Uh For science Posturings, anything for |
|
| 56:12 | No population. Yeah. Mm and you get it off of there. |
|
| 56:20 | right. So also different all the is hidden in the library. The |
|
| 56:30 | needs to worry about the sand routine sort of our in terms of the |
|
| 56:40 | called whether the underlying thing you can the door Tennessee. So That's why |
|
| 56:49 | of these 15 and the F. . i. Patient library that's the |
|
| 56:55 | person when they recognize what the hardware that too used to accept of. |
|
| 57:01 | huh. Called to actually make the complication. Um so then there is |
|
| 57:12 | I'm trying to put NPR library God. Uh huh First one and |
|
| 57:21 | some of it in the finalized asbestos things up. Uh vision. Uh |
|
| 57:28 | category any time. Third one is communication communication between processes. Uh huh |
|
| 57:48 | as correspondent things. So it's important keep in mind that is between processes |
|
| 57:56 | process source. Mhm There is nothing on the processes and process source. |
|
| 58:04 | there was nothing that's of course open . So I want to talk |
|
| 58:11 | Uh huh. The so called collective works so. Mhm. Um |
|
| 58:23 | I think this is best to be what I just said and some sort |
|
| 58:27 | different kind of boys. Mhm. these collective communications are and uh interesting |
|
| 58:42 | and good strength uh because you know so early on some implementations to well |
|
| 58:58 | libraries for this collective communication. So I think about uh confusing on the |
|
| 59:07 | . Princess the fools have lots of long as there's no lines coming into |
|
| 59:19 | so that means you kind of get equivalent of denial of service attack because |
|
| 59:25 | and any messages coming into the So that made some of the really |
|
| 59:33 | um very badly in place of someone collected communication. So it's very important |
|
| 59:40 | figure out how to scale things again terms of someone who's communications. |
|
| 59:50 | there is some over Oh and your . Uh huh dolphins or what types |
|
| 60:06 | africa? The 17 member. So let me uh let the product |
|
| 60:29 | about that Roxanne. Uh Well, are FBI works on palpatine prvs. |
|
| 60:37 | what involvement. Yeah. There there some toxicity ideas again, have the |
|
| 60:45 | pass is just not what I want do but there's a principle but the |
|
| 60:56 | problem uh these these incredible women. . But so you can you |
|
| 61:13 | implement you know the FBI is that want to do it across several network |
|
| 61:19 | is with your mobile what you're thinking they think it was best. It |
|
| 61:27 | uh this is our servers and have talk over if I see you. |
|
| 61:35 | protocol. But you wouldn't do that you want to do. But technically |
|
| 61:42 | make it work. Yes. So I need a product yet. So |
|
| 61:47 | we are just the right there for but we're going in the right to |
|
| 61:53 | programs for messages to the different Yes. Yeah. So I'm so |
|
| 62:10 | said, you know in terms of , you have an authenticity I implemented |
|
| 62:17 | europe for long network that will be to bacteria. But I don't think |
|
| 62:30 | any interpretation that natively supports one fire at all. No tv or some |
|
| 62:39 | the other seven for the falls that's traded what they send them to form |
|
| 62:44 | it doesn't because people don't just kind a set up to the spc or |
|
| 62:52 | computing. So I was mm uh name of it. But there was |
|
| 63:09 | am trying to the island use it you know, and you can |
|
| 63:23 | you know FBI across the network, know, land type services or |
|
| 63:34 | I already won right. You might able to do it. Uh I |
|
| 63:46 | think there's any FBI conversations that supported all right. Try protocol but participate |
|
| 63:54 | protocol on your right side. Nothing. Yeah. Oh, so |
|
| 64:06 | implementation of support of Cinnabon support is that uh huh supportive therapy. Uh |
|
| 64:17 | You know, it's stopping implemented on of the internet so there's a layer |
|
| 64:24 | for these protocols but some specific All right. Some FBI implementation support |
|
| 64:40 | . That's what you want to do ecstasy because it's too high overhead um |
|
| 65:00 | , call myself this my God. oh as you will see their example |
|
| 65:11 | concerts remember, wow, correct processes that they want to be different processes |
|
| 65:25 | a group. So when the box time that Saddam. Mm thank |
|
| 65:36 | Operations Operations Director, you may want things for those and columns or so |
|
| 65:42 | can create groups or processes represent the of the infrastructure or a roll or |
|
| 65:54 | block of That's a waste of creating of processes. NPR Yeah. And |
|
| 66:03 | as the subject of context because that's way you sure that among other things |
|
| 66:12 | communication state, I don't know the memorable patients. Your answer. |
|
| 66:20 | me too. So these two notions again, the example of today but |
|
| 66:26 | about that how the school to conflicts are combined into what's known as. |
|
| 66:35 | that means processes that are in the communicator having the same context that they |
|
| 66:44 | send information with each other. But right, there's a different process to |
|
| 66:48 | to communicate or change information between different huh the branch is the equivalent of |
|
| 66:59 | red eyed in open empty. And this is something more or less |
|
| 67:06 | same. So talk a little bit safe. Me tell someone it |
|
| 67:11 | So the because they were written something a simple model for that's a handshake |
|
| 67:19 | terms of sender and receiver agreement to that since our sending and receiving |
|
| 67:28 | But there's also nowadays are they on of the standard is started communications in |
|
| 67:40 | to reduce the overhead so and says sender and receiver to uh some degree |
|
| 67:49 | at least. Um I think so a process right? The song memory |
|
| 67:59 | or receive their uh other process agree what's supposed to happen and are some |
|
| 68:08 | the things that so yes also experimented during the summer in terms of the |
|
| 68:14 | sided communication, we can talk about in this next time at some |
|
| 68:20 | Next one probably do with demos of FBI works and the tools. Um |
|
| 68:29 | this is best they wanted a massive so it is uh what this does |
|
| 68:40 | for me that was all uh otherwise called the heather that has information about |
|
| 68:48 | receiver something else that is relevant for On the 2nd 1 to deal |
|
| 68:56 | So uh uh is payroll partners of data that you want. Uh Mhm |
|
| 69:11 | if. Uh huh And it's the idea is in the country to |
|
| 69:18 | Oh remember for the memory location for dog that they want transfer and specify |
|
| 69:29 | documented by income type. So the I'm into bikes or works that is |
|
| 69:39 | on the numbers. The fact. what is this character is you know |
|
| 69:46 | characters that X. Number of bytes are certain Double position that may be |
|
| 69:52 | for advice for 20. So it it out based on what type of |
|
| 69:59 | is the sound. The other thing this example chose that distance. The |
|
| 70:09 | says you know 7 13 elements of characters. Uh zero basically allocate space |
|
| 70:18 | 20. So they don't need to in terms of the company international types |
|
| 70:25 | attacks. Now talk and talk about too. So uh an envelope. |
|
| 70:40 | are and they just got to find this indicator. The best and name |
|
| 70:50 | are prostitutes. And this communication transaction the context something some sausages In the |
|
| 70:59 | out of this one. Yeah. . Book is community. It's all |
|
| 71:04 | houses. Uh huh. It is for the application religion. Right? |
|
| 71:15 | they didn't find out. Right. first community as a nation. So |
|
| 71:26 | center respect from the destination uh Good. Thank you. So it's |
|
| 71:38 | coming council Another five cases for what receiver. Uh Hard to treat this |
|
| 71:54 | message. And we'll be the example . Uh Yes. Mhm. It's |
|
| 72:10 | the intensity you. Right so a of bytes and what device me. |
|
| 72:19 | huh market in this attack to kind what type of information is that this |
|
| 72:27 | give it a summer receiver wants to one of his counsel's questions. But |
|
| 72:35 | I mean uh reflect you remember us some and something like the picture are |
|
| 72:43 | . It doesn't know its memory Wait, I don't think that I'm |
|
| 72:53 | to tell me that this is the . Yeah it sounds so you know |
|
| 72:57 | the memory So uh again data format doesn't know about it. Mm It |
|
| 73:11 | about the memory space and standard language tax. So I know it's about |
|
| 73:16 | from important single and other positions logic variables, everything all programs that |
|
| 73:24 | cars important by the FBI as data based on those you can do your |
|
| 73:30 | complex. They attack so you can the language construct I think that you |
|
| 73:36 | to do you want to you want format and then yes come in and |
|
| 73:46 | . Mm And we'll get fights another Syrian and you need to identify what's |
|
| 74:01 | size of each word inside nationally. in the asian markets them to basically |
|
| 74:11 | point or lift anything you say. we're gonna say to you fast there |
|
| 74:24 | to the other knows uh the No access yet current. No. |
|
| 74:33 | and there is the different notes. no idea on each other. |
|
| 74:40 | So it just gets goodbye to fight and then it's up to the receiver |
|
| 74:49 | where it wants to put this no relation to where they were member |
|
| 74:56 | picture on this, but it just out to be that couple months, |
|
| 75:04 | . If it's a sandwich, you go from one note to another. |
|
| 75:08 | it's broadcast them, it's just There are other constructs to them do |
|
| 75:17 | . So each receiving as a fraction a second. So the corresponding pixels |
|
| 75:26 | gathering have one source each of the our get the peace or war. |
|
| 75:36 | senators sets up the doctor stratification. is the broadcast, but it's gathered |
|
| 75:43 | device it up abusive the charm and . I have another person. I |
|
| 75:54 | that's okay. What about the So unlike mike open and the computations |
|
| 76:04 | china. Right. So I will for that fascinating in this. |
|
| 76:14 | so it's important to remember again that independent processes that hopefully about each other's |
|
| 76:22 | . So the university principle as you , it's right. Uh, you |
|
| 76:29 | another source and destination of any other . So for that record. So |
|
| 76:35 | to do this, take it from and there and then it just try |
|
| 76:42 | this identifiable command very by So I'm to dress and then instead of just |
|
| 76:47 | by explicit e allows you to specify count and type in order to figure |
|
| 76:56 | well and on the ending addresses. transfer is and then the time was |
|
| 77:02 | to them, uh, sort out to do with they overcome. Let's |
|
| 77:12 | . Yes, this is sponsor. um Yes. So I think this |
|
| 77:19 | also what I already said. So this this is a good month. |
|
| 77:28 | . So this I think so. is basically how you invoke an NPR |
|
| 77:36 | demo dot and this is now coming your question. Just take a |
|
| 77:43 | So in this case it's because the But one difference not better open and |
|
| 77:52 | all this said the first thing that from that this is the co |
|
| 77:59 | but he still has a song paul spending that what I'm saying, they're |
|
| 78:05 | 1080. You can donald you need tell this to find but that's not |
|
| 78:11 | most hold something done for that clusters the same called deceptive. So that |
|
| 78:19 | lightning open. MPI uh evening used coast. It's he's no doubt the |
|
| 78:29 | thing. So things get replicated like current region. Unless you have some |
|
| 78:34 | qualifying the exact case, it's that the same call to have its own |
|
| 78:40 | and his own program counter. So may not, it's about the |
|
| 78:46 | It's construction uh, cycle because all of things. But there's one copy |
|
| 78:53 | the code that offense feeds and then have their own program FBI scenario faster |
|
| 79:01 | . Each note has separate copy of company but it's a copy of the |
|
| 79:07 | . So unless thing, unless something done, just get it replicated that |
|
| 79:14 | are the ones for processes. You , the four copies of the things |
|
| 79:19 | it's not. That's exactly the same in this case. Except the difference |
|
| 79:25 | is code gets replicated. So I to stop measuring every note instead of |
|
| 79:30 | single. So what else did not ? Yes. Our area Hamptons. |
|
| 79:38 | so I guess I have another but it's up. But it's so |
|
| 79:43 | you don't want this to happen, have to do some way of valiant |
|
| 79:51 | they want this process to do. . And with open empty. We |
|
| 79:55 | the idea that this uh do this that's actually that depending. NPR is |
|
| 80:03 | the rank. That is the process . That's called rank in this case |
|
| 80:09 | opposed to bread. And so then can condition with this process, does |
|
| 80:15 | on it, Right? That's what do to Typical, that's what to |
|
| 80:21 | . That. You don't want every to do the same thing. You |
|
| 80:26 | them to do different things. And use conditional. Is And the rank |
|
| 80:30 | the identify other process to decide what want. It. Can you last |
|
| 80:38 | and guards and get specified captain inside . Yeah. Yeah. So I |
|
| 80:48 | . So, so I guess that's . Well, first the process just |
|
| 80:56 | piece of code. So they can any level of understanding, you |
|
| 81:00 | uh groups or whatever you want to . Processes and processes for other |
|
| 81:08 | Um Now it works okay then you also have several processes back to the |
|
| 81:17 | physical note. It helps answerable My dog is back So I have |
|
| 81:25 | piece of course. I tell that did a particular law to be run |
|
| 81:31 | one single. Well, that's not . Yeah, huh They can create |
|
| 81:43 | of processes uh initially when you launch NPR program uh so one of the |
|
| 81:51 | was called on board, what what is this? Initially you have |
|
| 81:59 | 30%. It processes we have a is in that world. Once you |
|
