Why are there so many people who just have negative things to say. Every hobby does not have to make money or even sense. There is the experience, the learning, and just fun. I mean it's like people who put extra lights on their cars. It's not my thing, and I would not use my money there, but it they are having fun who's place is it to tell them it's wrong. Well as long as it's not hurting anyone. So come people. Be kind. Or at least constructive.

[@magnuswright5572]

@Блядь Россия It's not a waste. There are a huge number of applications that benefit from being run in parallel, such as physics simulations and raytracing. For those specific use cases, that cluster can perform dozens of times better than a thousand dollar desktop PC. And in fact, if you pay attention at all to what he says in the video, that's exactly what he's doing: he's using it to parallelize a physics simulation for his dissertation, and I'm sure the difference in performance saves him days of time.

For anyone out there confused about what this cluster of computers are doing, he's basically simulating a real world problem where you have several computers/devices wirelessly communicating data to the same database at the same time, but in different instances.

Nice work. I stumbled upon your video as I was looking for alternative ways to power a RPi. (Now I know I need to fuse the line if I use the GPIO pins to power it).

He's programmed them to be one computer.

[@diegogarcia4255]

This is a cluster, the computers behave as if they are one PC.This is basically the equivalent of 32ghz and 16gb of RAM.The computer on the top is controlling the cluster, you don't use it's resources in the cluster itself..You can definitely produce a computer of similar power for much cheaper, and MUCH easier to design, but the purpose of this project. I heard some people call it a super computer, but a computer with 1 or 2 (at most) high end processors should top this, and you can put 16gb on practically any new motherboard out there. A supercomputer would be dozens of times more powerful than that. Anyways, looks great man!

I love the power solution! I was trying to imagine all those micro USB power connectors, but applying power to the header and adding your own safety fuse (and programmable LED indicator) was completely clever.

Many people will criticize the fact that it is indeed not worth for the computation power, but it is very interesting in terms of educational value for learning about server clustering, cloud architecture, etc... Of course you could do that with a couple VMs, but it's always more fun working with actual hardware ;)

[@hariranormal5584]

Its exxactly what it is for. many ppl here asked whats the use for this but yeah, its really useful to basically show how a single website can work in multiple servers, a datacenter does basically that but in a larger scale where each servers are usually dense enough, NOT too dense, NOT too light...

Maybe you should read his comments, this was done for dissertation and the requirement was a cluster. Yes, quad core i7 for $300 will blow the shoes off this thing, but this is not the point here.

[@teodoreh]

The problem is that so many facebook pages and stupid portals present this as a "cheap supercomputer" project. It is not. Ok, you can experiment with parallel processing with 30 or 64 nodes, but on the whole video I couldn't find a single piece of information about (i) total power consumption and (ii) total processing power of project (except the ARM processor frequency). So in conclusion, the whole project gets more attention that it should from people who look after something different. I assume that an OpenCL software on a single R9 280X will be x10 times faster than the whole 33 node project - and around 7 times cheaper too!

[@msh1044]

Well, as you said he did say he was going to overclock them to 1ghz each. But to cut the guy some slack, There are some valid scenario's for such as setup. 1) he could be building this as a prototype for an application he wants to run on a real big ass super computer. Which would cost money to rent time on. So having the behavior of your application across multiple nodes well tested will definitely help here. 2) He seeks to replace an existing supermachine program. But it's too risky to just "swap the program" and see if the modified version works. 3) He just wants to educate himself on the behavior of programs across multiple nodes. 4) everything else! Either way there could be many valid reasons for building this stack. And i personally think this stack was well executed.

[@dizzious]

So you're saying he can get more raw flops with a graphics card. Duh? If you had paid attention to the first 35 seconds of the video you would have noticed that he said he needed a cluster. While a graphics card would definitely provide more raw flops, that might not matter at all: remember that the ARM chips in the RasPi's are optimized and designed for different types of computing. If this guy's application is designed specifically to run on 32 individual ARM processors, then he's going to get MUCH higher performance running it on what it was designed for, instead of running it on some shitty consumer-grade graphics card.

[@yumri4]

dizzious i think you mised the part of when he said he is writing a paper on how this works ... never went onto which part of it he is writing about though. In that how would you be able to emulate a 32 node project on a OpenCL software program? it is a project on and about how 32 nodes work together in sync thus if you only have 1 node even acting as 32 nodes you will not be able to get the same result with all the same errors, bugs and gliches that needed to be fixed in it. Why the paper while probably because he is going for his master's and/or Ph.D thus actually haveing a 32-node cluster is needed even though he did go a little overkill with the power supplys and case fans. The power supplys could have been replaced with a custom power adapter made for powering mutliple devices on a 5V power line but not knowing how many amps are actually needed a PC power supply might have been the best solution not only the quickest solution to it.

[@teodoreh]

dizzious Which part of what I wrote was hard to understand?

[@yumri4]

Teodore Hatzikostas i think you missed the point of the project as it is a proof of concept device not an actual computing device there is a major difference thus yeah it has 32 nodes that can work together and all are overclocked to a speed that they could be synced at without noticeable latancy time but it is for a paper not a business nor a consumer application thus after he is done with the paper he will most likely either 1 keep it for future explaining about the how he got the data and/or 2 sell it to the university who sponsered it most likely as $1,000 for a device to just write 1 paper is a pretty steep cost to which is probably only going to be a foot note and/or a small paragraph in the paper while the rest is about how a 32 node system works together and how well. Again he mentioned that using the raspberry Pis was the cheapest way but still $1,000 USD is not that cheap of a price ... probably was that high because of the PC PSUs though to which he could have gotten away with only 1 and used a diffenret PSU with more adapters on to the wires but that is assuming any PSU on the market will have 4 independent 5V outputs with enough amps to power that thing.

Heya.. the answers ur looking for are near the bottom of description. Always good to read that; just like FAQs b4 posting in Forums. Anyhow, a single proper PC would cook the pants off this cluster.

Which could otherwise be used for protein folding or something...!

[@666Pulsar666]

***** Yeah. The answer is not that simple. It depends on the program you are runing. This is not built to run a game. It's built for parallel computation. Where you need to do lots of calculation in a short period of time or even realtime in some cases. It's like you want to compare apples with grapes, each one has pros and cons.

666Pulsar666 like your answer, thanks

[@Ciddyism]

>First, when your dissertation work requires the use of a cluster it is nice to ensure that there is one available all the time. I know what you are talking about. I had access to our "small" cluster some time ago. The task was to get the best way to split a task between all nodes and to compare different cases (1 giant task, long list of "smaller" tasks, ...) and to analyse how many samples should be taken and ... . So I threw my tasks into the queue and went home - every night. And after several runs and optimizations I compared the results and there was something wrong with the data. Sometimes the software was slower after optimizing the code - even after lowering the sample size it occured that the program needed more time. So I made my own small cluster on 4 computers and they messed up too. "Worst part": I found that the code was much faster from 6am to 8pm. So I waited..... and waited.... and I met the problem in the hallway. Big problem, simple solution: the administrator of the cluster gave one of his students direct access to all nodes - direct access was not written to the log normal users had access to. (Our main administrator had no clue about that so he had told me that the queue will log all tasks to the files I had access to.) The student normally waited for everyone to leave so his program would not mess up anyones work (-> time based problems in a program that uses timestamps only for benchmark and timestamps in the logs). And instead of using the >100 HDDs of the cluster he sent all data to his home folder / to our data server - which was the problem on my (4 PC) cluster because my home directory was on that server. So yes, it is nice to have access all the time and to be sure that nobody is messing with your data/work. (My RPi cluster has only two nodes (and one old RPi as control server and update proxy) yet but it's nice to use it - even if it is slow because it's still small. So thumbs up for your cluster.)

[@minecralex4497]

Jett Plays true, but since there are like 30 raspis connected together, I infer that several pi's will have much superior processing power, since 1 raspi can run Minecraft PC at about 10 fps, 30 pis should be able to pull 300 fps, that is, if the processing power is perfectly added up and used.

As a owner of the both boards, I agree with your opinion about the BeagleBone Black with some slight remarks : the cost of the both is not really equal, almost when talking about 32 boards it's non negligible. On the other side, the performances are really different too : while the PI use USB for the ETH the BBb have a true controller + onboard flash +2 PRU to go Real time, without talking about headers and capes which could ease clustering.

In general, this is a clever way to having 32 independent nodes, with independent and instantly available interfacing. A single pc would not provide this capability, nor provide the low latency this cluster delivers no matter how much more cpu power it offers (on a pc the cores are jammed in to one board and lack of independent interface ability and independent unison code execution).

The Pi that was used in this video is less powerful than the current Pi-0w. I imagine this could now be shrunk down quite a bit (though the wireless connectivity would be less desirable). This is still really cool... for the same cost as Josh, now using Pi3, you can get 4x the cores, with about double the speed per core.
