| 00:00 | Thank you. Yeah. So So any more questions on we can't |
|
| 00:10 | have some of you. I've been an extended deadline for the assignment, |
|
| 00:15 | that things are not working properly yet make any sense. But the new |
|
| 00:21 | before you have access, once you access to figure out increasing the number |
|
| 00:27 | days to so they you're not in access. Neither am I. |
|
| 00:37 | you should not make accountable. I that that's not true. one thing |
|
| 00:42 | would say is just The show is crossed 100. Oh, but energy |
|
| 00:58 | and one of us when you're if you have something, you |
|
| 01:04 | you can check on. Yeah. . And the other question. |
|
| 01:19 | Yes. Yes. That's what I . So once you have access and |
|
| 01:23 | reasonable turnaround time terminals at a number days finish it. But I can't |
|
| 01:30 | the deadline if you have no access meaning. So, so once it's |
|
| 01:37 | and you have access, then we'll up with please people. Okay. |
|
| 01:49 | instance, today I will continue and about FBI next programming paradigm first. |
|
| 01:59 | hmm. 20 times. Yeah. . That's quickly These things. |
|
| 02:06 | Very much talk about that very Once I talked about last time and |
|
| 02:12 | I'm talking about the rest of the on this side. No, not |
|
| 02:17 | of that joy. And that will in this one more lecture than today |
|
| 02:21 | the members of the FBI is programming that is typically labeled as clusters basically |
|
| 02:30 | collection of independent computers book together over form of the network at it kind |
|
| 02:39 | asked one more week, relatively the contrast into connection network that is |
|
| 02:45 | to have a great uh the notion a common system or the cluster. |
|
| 02:53 | the difference compared to what we talked before is that in this case the |
|
| 02:56 | gets replicated. Typically the spending So the program in this society typically |
|
| 03:04 | in each one of the processors sold this uh, memory for the cold |
|
| 03:11 | consumed in every process and not just . So the cold, I think |
|
| 03:16 | executed is just getting and uh so is that's a certain evidence seemed a |
|
| 03:27 | and that means to get them to what you do is what people call |
|
| 03:32 | the paramount. So basically you just the collection of jobs and there's nothing |
|
| 03:40 | going on between the difference notes in cluster that's typically out what NPR is |
|
| 03:48 | . You can use it for The interesting part when it comes using |
|
| 03:54 | is typically that you divide up the for getting a job done among the |
|
| 03:59 | notes in the question and since they're independent, that means the only way |
|
| 04:05 | you can exchange information between the notes by sending messages and that's when |
|
| 04:10 | I can't seem to place. And that means typically had a network class |
|
| 04:17 | I haven't, it's like, you , you're thank you have experienced. |
|
| 04:25 | . Is may basically uh heather to envelope put an address and all kinds |
|
| 04:32 | stuff and then you have the message could see inside. So TCP iP |
|
| 04:39 | communication protocols worked with that, which ahead of that have some information that |
|
| 04:44 | something about source, destination priorities, kinds of other features. And then |
|
| 04:51 | what I tend to call a lot of the time. That is something |
|
| 04:54 | goes into the um we talked about . Um and then there's this notion |
|
| 05:03 | communicators that we'll talk more about And then there was a little bit |
|
| 05:12 | just how you get around these programs NPR and the different languages. So |
|
| 05:18 | has bindings for and then to the older versions to see a few versions |
|
| 05:23 | fortune and even fighting that doesn't show here. So there's it's they are |
|
| 05:30 | used for programming and clusters And the show. So in principle because the |
|
| 05:37 | is replicated for Eastern on each of notes. And when you run NPR |
|
| 05:44 | that makes all the different notes execute same problem. Uh huh. So |
|
| 05:52 | got similar to they talked about in open empty regions that every thread executes |
|
| 05:59 | same cold and you can customize what threats do by using the threat. |
|
| 06:05 | The Target two different kinds of things they do similar things that I'll show |
|
| 06:10 | example about today. But the principal is replicated. So everything process. |
|
| 06:15 | does execute the same code so that you get us money. It's a |
|
| 06:21 | little Hello World program then, you , to get everyone to print out |
|
| 06:26 | same thing and that's fine I think fine. So and then there is |
|
| 06:39 | have been suffered. Well not you use a wanting to, he ran |
|
| 06:44 | something crashes down the hole. Program some things things get supported across |
|
| 06:52 | Uh huh. Yeah. Culture on dock. Unless you have ways for |
|
| 07:02 | responding to the miracles that is given Westchester compartment Germany remember. Oh, |
|
| 07:12 | was so alright. Any questions so ? Yes. So if we have |
|
| 07:24 | , let's yeah, That's 50 Republicans . I think that for me and |
|
| 07:31 | this stuff, it always does copy code to every note that you ask |
|
| 07:36 | . So in the beginning has served ? Simply ask for anything else you |
|
| 07:42 | . And they called this cockpits on old sucker of the UCC. The |
|
| 07:48 | doesn't it never of course. It doesn't matter. So like for |
|
| 07:56 | NPR is either the problem at the , the FBI distributes please. |
|
| 08:04 | so mascot, the count is And so whether it just excluded on |
|
| 08:17 | the notes, depends on you may the early part of the code have |
|
| 08:21 | positions uh, that executed by the distributed into all. No. So |
|
| 08:32 | is for NPR it doesn't do It's all in the program. It |
|
| 08:42 | to figure out everything. So I that that is my last time that |
|
| 08:49 | only notion of some global aspects is the programmers have. So I think |
|
| 08:58 | program I need to distribute the data it's given data. So you have |
|
| 09:05 | data sensitivity, you haven't done this somewhere and it's downloaded and they went |
|
| 09:13 | the hole there. So every note is kind of wasteful otherwise they need |
|
| 09:18 | partition the note the benefits among the for a test data that you |
|
| 09:25 | generate part of the data and it's of the nose. And so sorry |
|
| 09:34 | so but and towards the end of course, I will talk to you |
|
| 09:38 | the way so partitioning data sets so can distribute it so that well, |
|
| 09:50 | . So the other way of summit a little bit about the open sea |
|
| 10:02 | I was sort of the first such and basically in that case in the |
|
| 10:08 | member assistant, where does the data up? And it depends on where |
|
| 10:13 | first being used. The kind of or Mental Model one has NPR is |
|
| 10:23 | of owner confused less than you try get the computation associated with data for |
|
| 10:31 | of the data. It's so that computation happens, spending needs to have |
|
| 10:39 | between uh different elements and the So I will give examples of that |
|
| 10:48 | . Mhm. Not today. My soul. Think of it as the |
|
| 10:52 | compute rules. So you assign certain set to note. You try to |
|
| 10:57 | that data sets and most of the to the datasets. Um It's kind |
|
| 11:03 | local on the processor references. The is not on that processor is relative |
|
| 11:10 | treatment. So yeah I guess that's comment. So some distance that one |
|
| 11:21 | to correspondent today the barrel construct an empty. You have to start a |
|
| 11:29 | . Uh reason I don't for the and the state but there are empty |
|
| 11:35 | . It sets up everything parallel as captain. So I really really but |
|
| 11:45 | know like all the talks about his . You know sometimes uh what was |
|
| 11:50 | and there was parallel but then they or was interested in the pharaoh |
|
| 11:58 | So and then there was some clothes movements in sort of on the library |
|
| 12:04 | necessary. So now the first of example here is how to customize what's |
|
| 12:09 | difference processes do and the process is be more precise um as he said |
|
| 12:19 | some smoke mistake, things that And the ideas with process is not |
|
| 12:27 | the sorts we're going to step that's mapping processes to process source. So |
|
| 12:37 | Alright, so here is one thing you're wrong the process mm compute different |
|
| 12:43 | of arrest. Cool. Mhm. that's that's what I mentioned already. |
|
| 12:51 | you can use that the process ID a trend I. D. |
|
| 12:57 | So and the process. I didn't that. Right? The concept. |
|
| 13:05 | it's a name. What about that on this case? This is just |
|
| 13:11 | I. V. The restaurant This essay I fundamentally I rank that |
|
| 13:24 | of that France. The idea that but also the fact. What's your |
|
| 13:32 | is here in boston. Are you the other thing I was gonna or |
|
| 13:40 | there is also the emotional the communicator groups of processes that can't talk to |
|
| 13:50 | other. There is one that is defined. What is this humble? |
|
| 13:57 | all the same. So I developed and other processes and then they talk |
|
| 14:07 | them. I construct your own uh for particular application. And then there |
|
| 14:18 | just so there's something and I think was just a more compact when you're |
|
| 14:24 | the same thing but it's has shown to customize what the processes are |
|
| 14:30 | So they don't necessarily straight on the . Same thing. Um All |
|
| 14:39 | Something. So any questions on this . Right. Oh all right. |
|
| 14:51 | So something you know uh Very very my plan was fine but that's |
|
| 14:59 | In a smaller versions of these also times the use of that's the point |
|
| 15:11 | . Not something we'll decide. Yeah different the problem thing first everything starts |
|
| 15:17 | the FBI on this court about this Common to all the different. That |
|
| 15:24 | fine. And then it's a difference the rest uh si depending on what |
|
| 15:33 | once it starts with a capital letter , it's your case forcing on everything |
|
| 15:42 | . So they're not so a little about data types and there's all the |
|
| 15:56 | language, you know, types are . Um and from there it doesn't |
|
| 16:04 | much but funding that one may not about so much is that machine representations |
|
| 16:14 | numbers are not necessarily, it used be the uh and was well I've |
|
| 16:27 | for instance in terms of number representation been these notions a little endian and |
|
| 16:34 | big idea and I think, So it's a question of which it |
|
| 16:44 | huh work is the most significant, know. Right, most big that |
|
| 16:51 | significant or is it the most so you send and that's something that is |
|
| 17:02 | dependence is one down there and I'm to the harbor numbers are represented and |
|
| 17:09 | don't necessarily want the user to have figure out if this underground one of |
|
| 17:14 | noses, you know, by Another one is my idea then that |
|
| 17:19 | number of citations different you have to action. So all of that is |
|
| 17:26 | by FBI converted. So whatever data to have in the language son interest |
|
| 17:33 | between machines with different representations. NPR you can figure out you get the |
|
| 17:40 | thing. So there are a number a lot of the stuff that takes |
|
| 17:47 | of. That's more difficult. We so um, so this is pretty |
|
| 17:58 | saying that um, its advantages to to use the standard data types that |
|
| 18:06 | from the languages. So I think next few slides there's nothing particularly remarkable |
|
| 18:13 | it is just and it gives example what uh huh. Standard data but |
|
| 18:18 | is no standard data up in the that is not supported by NPR's. |
|
| 18:24 | is just subset of C and C and four chan again, whatever language |
|
| 18:31 | touch is available is supported in So and then there's some more of |
|
| 18:42 | predefined functions or functions that we talked . Oh, so okay. So |
|
| 18:55 | anti communist resort communicator communicators define processes. Yeah. Yeah the center |
|
| 19:09 | and this time common once officials and the numbers on your contribution because we |
|
| 19:21 | hang too communicators on uh find on court. Common is the name of |
|
| 19:29 | that lets us this is the first use the empire on this cool |
|
| 19:35 | You know that that particular variable and the first community. Okay. |
|
| 19:50 | questions on that. And I'll talk little bit about read your data. |
|
| 19:58 | . But to something that is it continues and expect it allows you |
|
| 20:06 | customize and all that. That means future. It's a deal again. |
|
| 20:13 | matrix objects or then you can define types in those roles or columns of |
|
| 20:20 | natures or sub matrix So so and whatever assignment two or three or something |
|
| 20:37 | we got some spots of light single standard engine Spotify algorithms. The |
|
| 20:48 | common one is just getting in the both columns. So the marijuana column |
|
| 20:53 | nice objects. That's when they want treat abstract instead of just enumerating the |
|
| 21:02 | . Oh and so to use So the deal is the simplest or |
|
| 21:20 | these to counteract the known facts. processing this constructive example the next few |
|
| 21:30 | . But then when all sort of the you know advocates today that process |
|
| 21:34 | growth practices that the arctic are false you. Yeah so there are some |
|
| 21:47 | the thanks. I'll get example about they use the radio data base that |
|
| 22:04 | . So basically in the way of instructors from the acceptance. The one |
|
| 22:10 | is so there is a few of space And then the director and the |
|
| 22:19 | one space sector and discounts. Uh release okay you are certain attributes of |
|
| 22:33 | function is divine vice. Otherwise it's terms of what element reduced. Uh |
|
| 22:45 | And this is just a way of education come in. Yeah remarkable |
|
| 22:58 | So now just examples I promised the types of after this the instances oh |
|
| 23:09 | is oh that you want sorry. this example the council stand so the |
|
| 23:20 | type. It will and you can on cities. Well they will cut |
|
| 23:35 | structure isn't too much so there again depends on what the old type is |
|
| 23:42 | a floating point integration structures you can the same thing and there was this |
|
| 23:53 | I think now. So what's basically i structural system thing. So this |
|
| 23:59 | uh in addition to the account Yeah planes that tells you how many instances |
|
| 24:06 | one all all types and then we also science right. A division between |
|
| 24:19 | instances of that song created. So you play so that that's it |
|
| 24:32 | For example, for that comes to international arrest warrants and then this is |
|
| 24:44 | showing the same pretty much total and all these structures that are just simple |
|
| 24:53 | data types and this is the age just chose the only good things and |
|
| 25:01 | . This case started taking lots of . Oh yeah, I remember. |
|
| 25:10 | . It is more flexibility in terms uh huh Credit Simon doctor song and |
|
| 25:23 | fact in its space at this. friends of his army the same |
|
| 25:31 | Whoa. Associated displacement from the start decent source zero A for instance a |
|
| 25:47 | and then I was outside too totally bill having general structures using his tonight |
|
| 25:57 | the types. Mm hmm. Here is kind of one way thinking about |
|
| 26:08 | Remember three dimensional arrays are find the come into London national structures in the |
|
| 26:19 | making orders but it seems important. I'm really certain access is The straight |
|
| 26:32 | accident within a column. Not that line. So for instance they wanted |
|
| 26:39 | send the column to another. No can't access. My friend was just |
|
| 26:44 | to find it's also uh and said that's classifiable deal with after this now |
|
| 26:52 | up it is C. And you column then successive elements of the |
|
| 27:04 | And that is the question for what do. Well the battle of So |
|
| 27:10 | the elements and one element at a uh this conference is done does sending |
|
| 27:20 | into the start uh there anymore I would be long. Yeah. Yeah |
|
| 27:30 | is the stuff from the start and one sees them in concerns. There's |
|
| 27:37 | wrong with it. It should work it's not what you would like to |
|
| 27:45 | . Thank itself. Yes. And does it make itself? Yeah. |
|
| 27:55 | huh. So there is the overhead have to construct. Uh huh. |
|
| 28:03 | the fact that the deceptive or not and uh from America every time not |
|
| 28:12 | go never element there's also over the and then the communication forget itself just |
|
| 28:20 | one. And for all the overhead that uh they have the 100 science |
|
| 28:29 | processing network. Yes. That's very . So what you would like to |
|
| 28:36 | is best exactly how did it happen that's where again this directive notion um |
|
| 28:48 | put solid, this is by forming specter. Uh huh. Then there's |
|
| 28:54 | talent there. NPR and are too . The fact you could have done |
|
| 28:59 | yourself by first minute temporary rent, the columnist somewhere else in memory and |
|
| 29:06 | go and get this. That's a block of memory and put this, |
|
| 29:11 | it to another process. But this the FBI to figure out and potentially |
|
| 29:18 | here memory cards because the memory read from memory right back to memory and |
|
| 29:27 | communication software needs to go and grab out of ever again you and that's |
|
| 29:32 | I think the best card and put out on the network. So to |
|
| 29:38 | oh that the implementer of the FBI from sending stuff. And I figured |
|
| 29:45 | how to avoid that some memory copies order to to the column by using |
|
| 29:51 | the fact in this case. Any and that. So that's what I'm |
|
| 30:03 | them many times. In particular scientific complications in many cases. Yeah. |
|
| 30:12 | , well structured data not necessarily raised race and by no means uncommon and |
|
| 30:18 | this case they want to have different of access parents to multi dimensional race |
|
| 30:24 | then extract example. Uh by defining data types of just crabs, four |
|
| 30:32 | to certain elements of the common All right. And then you can |
|
| 30:43 | the same possibly some matrices. so many different. The loss of |
|
| 30:50 | is essentially to .2 subsets of data then the NPR libraries can figure out |
|
| 30:59 | to effectively combine it. You bigger on this side essentially. I said |
|
| 31:09 | depending upon its is constructed and used uh here more work to figure out |
|
| 31:18 | to disassemble it the previous simplest so it's a little bit more involved. |
|
| 31:29 | better. More work in order to the factories. Okay. So no |
|
| 31:41 | there is any questions on this data , but it's something that is it |
|
| 31:47 | useful. Okay, okay, so very many uh these communicators. |
|
| 32:07 | ? Electricity. The structures has some information about the processes that particular |
|
| 32:16 | correspondent car. Seriously. So thank for it the right. And these |
|
| 32:41 | are local to communicator. Most similar what was the key? Whatever |
|
| 32:56 | Red eyed was going up to the . So one has x dependents. |
|
| 33:05 | , numbering started again. The minister some Uh huh This kid back off |
|
| 33:15 | remains yourself other rights are for this of picture. I've been in this |
|
| 33:23 | of the work again at all. process is absolutely process. Mhm. |
|
| 33:31 | and uh solo communities construct uh huh constructive financial too. Mhm And but |
|
| 33:46 | the uh oh, a few hours . Right, okay. It's very |
|
| 33:58 | . The sauce still are you doing the communicator? So once this |
|
| 34:07 | what is it? That's the most both? Hey, playfully. And |
|
| 34:18 | exactly some messages within the different There is also a way of sending |
|
| 34:25 | between communities and most Oh right. are uh yeah the list of the |
|
| 34:41 | that useful communicators or just information. ? Uh huh. Cool acceptable to |
|
| 34:55 | it for I will fight conclusion from intended us to have established order, |
|
| 35:06 | Okay. Yeah. I don't see of the war. You know how |
|
| 35:14 | processes you have been? Yeah. . That's an example of this career |
|
| 35:28 | . Sign that to the point or a picture of communicators. Yeah. |
|
| 35:36 | the back of the process. It not. Is there a phone? |
|
| 35:52 | . I mean questions and comments from stage so far. Colonel, number |
|
| 35:59 | things to keep track of but hopefully not. That's difficult Fernandez an |
|
| 36:07 | Uh well the state is dividing up homework processes group. The ones that |
|
| 36:20 | even uh oh yeah. First thing politics in a rack. So let's |
|
| 36:32 | . Yeah. Yeah. Iron. , back to Harrison. Local conflicts |
|
| 36:42 | this time. Go work on. right. How many they probably even |
|
| 36:54 | that are. This is a Mm uh report. Mm hmm options |
|
| 37:09 | then I want to do uh exclusion schools. Hundreds. Show us an |
|
| 37:19 | of a house but effectively are for U. S. Number Processes and |
|
| 37:28 | work with the one room from the . Donald trump. Okay, hard |
|
| 37:35 | . The world's fast started. And this is strong. That's one |
|
| 37:43 | the process is accomplished. Oh So like on the side uh and |
|
| 37:56 | the different processes right down they are . Uh huh. Right now here's |
|
| 38:04 | advice. Uh What the Yeah one ranking buck install There are four officers |
|
| 38:20 | And three our bloodlines. Yeah. . Yeah. Well this is just |
|
| 38:34 | way of showing that they can use of this NPR functions to give zero |
|
| 38:42 | , subsets of processes. Any All right. So next is the |
|
| 39:01 | codes. Let's see. So this a bit uh I don't know. |
|
| 39:11 | would say oh uh send and receive in the number of the checkpoints Serious |
|
| 39:27 | different ways. And uh Another form is of 12. Um No, |
|
| 39:38 | gone through a lot first this or a senate and stuff in this evening |
|
| 39:46 | then talk about the um Right so a question what happens once you |
|
| 40:02 | Yes sir. There's some culture something . It's fresh. Um So one |
|
| 40:14 | this is the seven commanders other process process me that also had a correspondent |
|
| 40:25 | scene craft you see. Well uh sir. Mhm No, but things |
|
| 40:37 | since I remember oh the effort in cars on a lot that's questionable. |
|
| 40:48 | is it safe? But actually override you want. Percent dun part |
|
| 41:00 | Yeah senator. Uh Resistance. Uh . So it's not until there is |
|
| 41:16 | fact. Yeah. There has been problem. All right. Uh |
|
| 41:23 | Uh huh I don't know. So completion of the sun is stop there |
|
| 41:34 | but and then the synchronous son. Yes. Uh I don't think so |
|
| 41:49 | think they have to think that book the so the transit sinfulness I guess |
|
| 41:58 | should thanks clear to be given after independence computers basically communicating they don't necessarily |
|
| 42:08 | on the same clock speed or anything though they have the same code they |
|
| 42:13 | not be anywhere close to the same in their coats to give it |
|
| 42:19 | So it's totally I think that's what . And the messages are sometimes used |
|
| 42:25 | synchronize them and sometimes not. So one thing where some of it is |
|
| 42:32 | completion and somewhere it depends on what other processes and right the bumper boats |
|
| 42:47 | um so that's six. Yeah because still cooperating at once. So it |
|
| 43:02 | some of the applications responsible to make that things are probably stop the week |
|
| 43:12 | the code event always point for local because it uh for the most stringent |
|
| 43:31 | matching and the sender and receiver of that tell ready at both sides to |
|
| 43:37 | exchanged information so course analysts. The Virtus so I don't think so all |
|
| 43:54 | ones are sense of it or at level they are the codex stop events |
|
| 44:05 | uh and I think according to the different most done where is a non |
|
| 44:13 | son uh the the program complement. accent something uh just moves on but |
|
| 44:28 | problem and to make sure that to results have examples here on what the |
|
| 44:40 | are different since commands and questions on sample. So the sand molds we |
|
| 44:48 | , it certainly can affect performance a because whether you'll wait for now, |
|
| 44:55 | it also is in many cases criteria for the correctness of the code. |
|
| 45:02 | don't get over overwritten before it's safe do. So Okay. So this |
|
| 45:15 | a non blocking in Egypt I Uh huh Well, uh huh |
|
| 45:26 | Radio spectrum that's fine. The vocal that needs to The transfer to five |
|
| 45:38 | starting application. The number of them of the United States rights that this |
|
| 45:44 | to transfer on the destination personal Uh No, no. To be |
|
| 45:52 | the context of the communicator. So know, saw the started, |
|
| 45:59 | Didn't sound that part part of Mm All right. What a correspondent |
|
| 46:17 | in terms of open, empty open sec. And that they can |
|
| 46:23 | a little bit called progress. two little girls from here and |
|
| 46:34 | saga sounds just anymore. And so the number of performance, but sure |
|
| 46:52 | parents salts and and there's for some talking first. Yeah. Oh, |
|
| 47:12 | of this. Yeah, It's all it. And that's saying off from |
|
| 47:30 | huh And yes, it's not just me so that we don't have a |
|
| 47:50 | , more concrete example. Uh huh Oh, something. So, |
|
| 48:03 | so it's just process there are send to pass the buck remarkable. |
|
| 48:13 | But for innovation and under like a this process. The center for |
|
| 48:21 | Uh specifically? Uh huh. Yeah. Local farmers. Oh |
|
| 48:35 | His blood bar here here there is process. Uh huh, slightly larger |
|
| 48:43 | . Right. Send it because they're young. Maybe a design about |
|
| 48:50 | But this does not necessarily have. now it's, I'm not sure FBI |
|
| 49:05 | in case you specify a smaller at space. I don't know if it |
|
| 49:11 | checking and the course things or just a professional comments. I think it's |
|
| 49:21 | responsible. Right? How long? , okay, likely as possible. |
|
| 49:35 | , so aside from that, I there are lots of flexibility. So |
|
| 49:41 | as the footprint on this, what call the practice, the volume of |
|
| 49:48 | best table size. It's and receiving . You can also take sensational, |
|
| 49:59 | the continuance and receive it as a . As long as memory spaces there |
|
| 50:06 | lots of flexibility in tax on How to interpret the data that does |
|
| 50:14 | need to be the same home sender receiver. Mm hmm It's the same |
|
| 50:25 | . I'm just pointing it out. think of this central figure. |
|
| 50:31 | So yeah, so anyone maybe. , so we're going over this |
|
| 50:48 | Not so what else is there to out why this is not difficult. |
|
| 50:55 | adult. Good explain what both but Oh yeah, not sick. |
|
| 51:28 | Yes. These are not the Oh. Mhm. Oh my. |
|
| 51:41 | huh. Uh huh. Okay. think so. Not cool. |
|
| 51:52 | What the non expired What's on the of this 1? Um Probably fun |
|
| 52:01 | the road. Uh huh. From General. Yeah. As far as |
|
| 52:18 | order of 15 is the ceiling. . Uh huh. Here borders. |
|
| 52:32 | it's really the final sentence of America okay for registration center. Yeah. |
|
| 52:47 | and the I'll do the purpose of call. You may not happen in |
|
| 52:52 | council of sanctuary, the council So in this simple example probably I |
|
| 53:04 | you to get hurt. The data discovered form more comfortable in program sends |
|
| 53:12 | receives straight up and enough piece of . So there's no I shouldn't expect |
|
| 53:20 | a couple men off fine in the process. So you can probably use |
|
| 53:35 | and figure out that spends for every and that before it crashes all we |
|
| 53:40 | to given classified. So. most likely would. I'm telling you |
|
| 53:49 | start kicks it up. Oh But you can put a check. |
|
| 53:57 | ? So so this is based on this is certainly a simply flip. |
|
| 54:06 | . That's something but it's against something the conscientious although ordering is important in |
|
| 54:13 | country receives. So this is all trying to explain. Uh. |
|
| 54:24 | Right. In this case it's a who could work depends on water. |
|
| 54:38 | . Thanks for being from trying to it out and it gets to the |
|
| 54:42 | side standing on the bus which inside this is one way or time um |
|
| 54:51 | also combined Senator see Oh Korea or our conversation and if you start and |
|
| 55:00 | so help and get the water Oh so if you want to swap |
|
| 55:06 | between two processes using Senator Z have in both processes, we're going to |
|
| 55:13 | me out will fix it. Service something example. So the reason |
|
| 55:33 | simple. Uh Oh yeah and the of some cream sent there actually the |
|
| 55:52 | . I so yes it means these blocking uh the cold I decide will |
|
| 56:10 | progress until uh enough of this exchange thing place but I'm not sure um |
|
| 56:24 | depending on offer sizes that absolutely One before the other one. It's |
|
| 56:38 | It's a good question. You have space um one sense and has allocated |
|
| 56:53 | receive and then even may not from received over but there is not a |
|
| 57:06 | . Thanks go back. Yes it's one way to avoid that that |
|
| 57:15 | Right, so that's concerned. So sequencing is done right. Uh huh |
|
| 57:21 | huh. Someone sends and receive and it certainly can also send stuff to |
|
| 57:35 | next the seeds. So as long a buffer on the processor there, |
|
| 57:45 | first one but that's not sense in light phone I don't think the buffer |
|
| 57:52 | of it's principal. Uh huh Depending how the engine that implements it can |
|
| 58:03 | center guard can move on and potentially that buffer and then because the receive |
|
| 58:09 | and I'm not farms, it's write them down percent before that's |
|
| 58:20 | Business and you know it is for , you see. But the bucket |
|
| 58:26 | there someone in terms the can receive ? So All right. You |
|
| 58:37 | All the same that you're not just , well, no, it department |
|
| 58:45 | find a solution and then we have plans that some people say that office |
|
| 58:53 | in. I didn't no, I'm having this but it's a rocky bob |
|
| 59:03 | you can be sure that was the to execution finishes from this uh called |
|
| 59:11 | the next line, whatever you Oh guys, The other two expectant |
|
| 59:19 | received from Yeah. That obviously we from the another record faster. Yeah |
|
| 59:28 | . Inside this call the order may be that definitely something like that. |
|
| 59:35 | was personally wants to send the Are you want to play for receiving |
|
| 59:43 | soon as it comes out of? very well, wow, I don't |
|
| 59:55 | the exact 30 months please thank Things have to be posted. Both |
|
| 60:04 | right now that the actual execution is something so once it's posted on both |
|
| 60:14 | and so then it serves the correct things can see the different rates of |
|
| 60:19 | two sides will be my interpretation. . Generally the implementations of NPR as |
|
| 60:31 | something happened one or some set of can put the data that you present |
|
| 60:38 | locally as well and but they can all that difficult. Yeah, nice |
|
| 60:45 | see that the second but first thing the senators involved what might be uh |
|
| 60:58 | one of the spy service must guarantee the receiver yes, absolutely. Corners |
|
| 61:09 | huh restrictions. Mhm Right, so Extra piece of information. Mhm Experience |
|
| 61:33 | is a there are some and behind that can differentiate whether you're communication because |
|
| 61:41 | going across the nose or within the so you can have several processes inside |
|
| 61:47 | people inside Yeah, 48 course one everyone else is huge. There can |
|
| 61:53 | for the box that and the lever was Crosby not electricity idea. And |
|
| 62:02 | nowadays there are several frameworks that can upload your local manifest for a lot |
|
| 62:11 | thinking back and to the member can published with them share uh huh environments |
|
| 62:18 | doesn't have people going to adult. , right, active. So I'm |
|
| 62:28 | that going about processes and processes across source is the circus stage. Many |
|
| 62:37 | in the same process. So that that the of practice, you need |
|
| 62:51 | assemble to some things across an effort i overhead compared to memory reflects but |
|
| 62:57 | the end it processes jumps in the note, it's all about just the |
|
| 63:02 | of Russians, all these creating messages all centers and all of them. |
|
| 63:09 | , very high over. Oh really behind in conversation but realize that these |
|
| 63:15 | now running on the same process or his memory references and moments. |
|
| 63:21 | Different recognizable doing what I want but not implemented. Are you one of |
|
| 63:29 | ? Mhm. Such a personality Right. Yeah, that's a global |
|
| 63:43 | be there for them. Right. FBI is a standard. Yes. |
|
| 63:50 | there are different implementations. It's on of the national lifestyle. Yes. |
|
| 63:58 | there's in this open mp that is source and dial developed by the community |
|
| 64:05 | then the vendors tend to have their implementations trying to optimize things for their |
|
| 64:13 | . But again, the network is necessarily the offender's point. I can |
|
| 64:19 | into servers and when I go on network from somebody else and there's lots |
|
| 64:25 | effort for the calling is an art on the network interface, cards and |
|
| 64:31 | and all of that. It's something the wonders don't come. No, |
|
| 64:36 | really is. What's that? Right. So the arms are |
|
| 64:49 | Can you repeat that a question? the same question. So mhm. |
|
| 65:05 | we have the servers and they have are you busted as you should use |
|
| 65:13 | for connections and cost then how do need to cut service? There is |
|
| 65:24 | have a small buster human. This connection between a conservatory switch and this |
|
| 65:32 | of one half thing with is to a larger network and several layers of |
|
| 65:41 | that uh huh the structures or rashes collections of switches and uh, switches |
|
| 66:00 | . So you can have the best that I mentioned before and uh it's |
|
| 66:06 | to be about protocol and also support a property that uh, the mail |
|
| 66:16 | you can get whatever flavor long 10 or whatever about the switches starts. |
|
| 66:23 | protocol. And depending upon the switch has different amount of buffers. So |
|
| 66:31 | you optimize things for the next Depends on the particular speeches. Uh |
|
| 66:43 | And then also some of yeah software me. I may run on top |
|
| 66:59 | support removed uh direct memory access so several practice in the processor and expects |
|
| 67:08 | and so on that. He just the minimum number of cycles for the |
|
| 67:13 | for access other processes that they think the memory director senate basis and the |
|
| 67:23 | memory person Oh, I found out answer the question. That's what the |
|
| 67:32 | hearing stage with the positive, you , next time and lots of |
|
| 67:44 | I am not. Yeah, different are how uh yeah, probability of |
|
| 68:02 | NPR that's kind of more or less of the er itself joint as far |
|
| 68:09 | annoying. It was all in conversations the discovery americans figure out well switch |
|
| 68:17 | that are I think in that case opportunity and you figure what knowledge want |
|
| 68:27 | hurt. I don't uh that's a question because that what you're asking and |
|
| 68:38 | students trying to figure out and so now state of the art, |
|
| 68:48 | immigrants, which is, um, fits the vendors of big networks for |
|
| 68:58 | performance, these customs, they have own software for congestion control during that |
|
| 69:16 | to be some people for reactive because is that something has gone back and |
|
| 69:24 | can try to prove it and others trying to be proactive. four things |
|
| 69:32 | congested, charge balance ability, network , airports. Yeah. Traditionally, |
|
| 69:41 | of them they need to use the table, but they're there if you |
|
| 69:45 | to go to that destination, it's wants to know that small, attractive |
|
| 69:50 | track of the traffic patterns before or . And I'll talk about that. |
|
| 70:00 | that sort of if there's time I talk, but it was the head |
|
| 70:09 | the party for some time because, . No, it's a lot. |
|
| 70:19 | , uh, let me just make few more comments and then I'll talk |
|
| 70:24 | about the next step that it was communication Set up the context 1st. |
|
| 70:30 | so what it is, Yes. like, uh, broadcast reduction. |
|
| 70:40 | the opposite of broadcasting sometimes and got scatter operations for you distribute things |
|
| 70:49 | So let's try to, I think next month conduct together standard operation |
|
| 70:55 | So the broadcasting station, Yes, in some stuff for you enforcement reduction |
|
| 71:09 | , it's something different. Okay, going to do the opposite. |
|
| 71:18 | Foreign conference data. You want to the data and on Tuesday let's work |
|
| 71:25 | . Conflict is old different parts of work. So that's something Yeah. |
|
| 71:32 | their spreading into abusive. Yeah, both. So these are known as |
|
| 71:40 | computation in the sense that it is . Yeah. Other ones that send |
|
| 71:47 | disappointed .1 step to the receiver. those numbers of the form communication, |
|
| 71:53 | is kind of a little competition. . All right. Uh, so |
|
| 72:03 | are um, a barrier notion of that you need sometimes to synchronize and |
|
| 72:14 | that day comes people so talk about or sometimes who for incremental investments, |
|
| 72:27 | . It's a dedicated effort in some they don't use it all on |
|
| 72:32 | So sometimes in the past that's at three efforts. There's one for system |
|
| 72:38 | doesn't appear with data communication. There's important communication will step out and then |
|
| 72:47 | another one for synchronization Many times three efforts. So it's like I think |
|
| 73:02 | goes on there are your best Pizza . That tends to be the thing |
|
| 73:06 | goes the data communication. That is , high landed management is typically just |
|
| 73:13 | infinite communication of very high speed and synchronization. That doesn't take many |
|
| 73:23 | That's various sort of the network, it's important that is turn it all |
|
| 73:31 | and see. So that's why the types of networking. Uh no justice |
|
| 73:38 | serious high performance computers. The next slides is just illustrate thing again, |
|
| 73:46 | we already saw the other cartoon slides what it is in terms of |
|
| 73:51 | And we have the example of what broadcast is. There's so much remarkable |
|
| 73:59 | to say about that. Several things reduction where they have a notion more |
|
| 74:05 | examples and then the cartoonists frontline and such as what they uh huh. |
|
| 74:13 | are not for the reduction. And an example of that. And |
|
| 74:19 | we have had this same example for empty in terms of computing device and |
|
| 74:24 | it how you do the same thing work on an empty and then we |
|
| 74:29 | a couple of examples together scanner but not different from the other side a |
|
| 74:33 | bit. Just details the wanted and think that's pretty much it for |
|
| 74:44 | Uh stop there any more questions. saw that main concept in the numbers |
|
| 74:54 | governments, other cities. Uh huh to memory references is very expensive |
|
| 75:05 | Yes. Yeah. Fact that veterans the bus, it's all part of |
|
| 75:12 | with the information that how I implement fact that company. Mm Yeah, |
|
| 75:24 | through there about the cut. So former health something more more and more |
|
| 75:32 | what's been produced with annual his But the first time of course. |
|
| 75:44 | yes, all kinds of ways. efforts. Thanks disseminate. Tell you |
|
| 75:52 | you wanted to do. My sources priorities. Sign something and stuff. |
|
| 76:01 | are things you don't need to worry it because the social members, all |
|
| 76:06 | that's local and it's just memory Yeah, They have an everything. |
|
| 76:12 | next move. Okay. Thank you today. Oh, that's the |
|
| 76:30 | Probably right. |
|
