First of all your videos are amazing. So simple and to the point. Cluster computing is something I have been curious about for a while. Also a episode on x86 clustering would be awesome. Can't wait to see Part 2
since this is supposed to be a tutorial, it would be nice if the commands you typed were on the screen for more than a split second. That being said, I used this tutorial and got it to work, so thanks for posting!
Oh my god, you sir have just made my day! If I had a credit card and a source of income, I would patreon you so hard right now. Keep up the fantastic work! Can't wait for the next one!
My second Pi just came in and I cannot wait to try this tutorial! Fingers crossed. I am using my two VERY 100 FT Long Ethernet cables plugged into the same router for this experiment, my 24 port ethernet switch comes in, in about 4 days so I am definitely excited! I want to make this project for my school - just to represent the fact that I love computer related stuff for no reason. Of course I will find a way to utilize this cluster once I have made it on a bigger scale :) Thanks tinker!
I'm also interested in a method to combine 2 or more computer towers 2 like brands and maybe a 3rd an 4th of different low budget brand computers towers
Around @2:00 mark, or you could simply use Berryboot to get the operating system installed on the Raspberry Pi. Pretty easy and you don't have to subject yourself to Microsoft Windows during the process. I grabbed the Berryboot loader from the internet using my favorite GNU/Linux distro and then put that on the SD card. After that was done, I ran the Berryboot loader on the Raspberry Pi it's self and then did the remainder of the operating system installation process on the Raspberry Pi. It's completely a Microsoft-less experience for me and very simple and was completely graphical every step of the way..
Thank you for the video. But honestly, it's no wonder why these pi's are not popular. The code learning curve is WAY over the top even for most PC enthusiasts.
Hi, actually I really like the style of your videos and over the past weeks I've enjoyed many of your projects and most of the jokes too. :P Especially this video helped me a lot regarding to a problem I've had in my very own little project starting a view weeks ago. So please keep on doing that helpful and interesting content. Best regards, JMS
+WeakEnough I literally was having the same thought process when I read your comment, except it was only 11:26 p.m. and I had to get up at 4:00 the next morning.
maybe... it would possible but it would take a little soldering (possibly bricking both) and some coding. i don't think it would be that bad... especially if its x86 (uses an AMD FX, Ryzen, etc. or almost any intel core CPU like an i3,i5,i7,i9
Why am I watching this when I don't even have a Pi? *sigh* off to the nearest Walmart and getting me some Pi Which Pi should I get? There's apple Pi, lemon Pi...
I can't imagine this would be cost effective when stacked against a normal computer for processing power and efficiency. Sure you have more cores, but are those cores going to outpace something with one forth the number but several times the power?
I know this is pretty old, but I wanted to post this, because I immediately thought of this video. This is a project I've thought of doing many times, after all, a RaspberryPI cluster computer is a nice and - relatively - cheap expandable computing system for small scale projects. When I saw something on the RaspberryPI's website, however, that made me really exited. I'm talking about the RaspberryPI compute module. They are tiny little cards ( they fit into a "standard DDR2 SODIMM connector" according to the website ) that are fully RaspberryPIs meant for industry use. However, I think they'd be freaking awesome for cluster computers. The idea, is create some sort of casing system. Just buy a bunch of DDR2 SODIMM female connectors, since they seem pretty cheap, a single RaspberryPI, wiring tools tools, and some material to make the case out of. You'll also need the "Compute Module IO Board" to flash the OS of the chip. Once you build and wire up your case, you'd have a very easily expandable cluster computer. Here's how. The OS you'd flash onto each chip is merely a network boot system. I haven't looked much into the specs ( so all of what I'm saying is mostly speculative ) but I'd assume there are pins for what would usually be a female ethernet adapter. Essentially, wire them all of ( splicing them into ethernet cables if you want ) into a switch system to create a LAN for all of the female DDR2 connectors, and the single master PI. This way, once a card is slid in, it would be given power, network boot, and thus be given an image already setup for cluster computing, with all of the various certificates, keys, softwares, etc. already on the system. Then, it boots up and connects to the cluster. To me, this seems like a very nice method of creating a cluster system. Easily expandable, and are slightly cheaper ( $25 per card ) then a regular RaspberryPI. They're also much slimmer, and to me, this sounds really aesthetically pleasing. Basically, you've created a server rack, only instead of the thousand dollar computers big data companies would insert, you insert delicious PIs. Since this is meant to be imbedded and soldered right onto a project, it also seems like it would be great for a project like this. It also says you get every more GPIO pins. If you really wanted to use pins, I'd image you could create ports in the back of the case ( using either a parallel cable with enough pins, or a serial encoder/decoder to use something more modern, like a USB-C cable ). Adding and removing cards seems really easy, and in fact, they even have a Lite model, which doesn't have build in SD-equivalent, instead giving you access to the what-would-be SD card pins. Meaning no need to even flash a OS before hand. Simply connect all of them directly to a SINGLE SD card, with the network boot already there, or even Raspbian with the cluster firmware already installed. I don't know about anyone else, but this makes me pretty existed. Seems like a really compact, easy, and frankly pleasing, way of creating an expandable cluster computer. Start with a single PI, then another, and another, until you've filled your entire rack. Again, I'm not entirely sure about the plausibility of all of this, but I think that if possible, it would be a cool video. Plus, because of these cards size, they are also great for more compact projects you may do, such as you Smart Car project, using a card as small as this could be very good, especially when you know you won't be opening the casing, just to use a USB/ethernet port ( and thus, those ports are waisting valuable real-estate ).
Correct me if I'm wrong, but once you factor in the drops in connection speeds from the Ethernet cables and wireless connections, this is really only worth it if your program literally requires cluster computing.
alright, I am interested in making a handheld console with 2 raspberry pi's (rpi3 +rpi2) i keep looking for a tutorial on how to make a 2 node system with no luck, also i keep hearing online: no, clustering your pi's will not make the system run faster. then what does it do? if someone could help me, that would be great,
Hi! I am an indie filmmaker and tech enthusiast and I've been reading a lot about raspberry PI clusters. I was wondering if you'd be able to help me. I'd like to use it for large file processing, such as rendering 3D vídeo on blendr and generating dcp files. Is that possible? Also, I have a couple of secondary questions that I hope you'd be able to help me with: 1- Can I use it also as a "regular PC"? I'd like to run Ubuntu on it 2- How would I plug it to a monitor? If there's multiple boards, can I control all of them from a single screen? And combine their forces for a single activity? 3- Do I have to use identical boards or can I get different PI models? Thank you!
I have two theories that could possibly make processes like this faster a lot faster. The first one would be I don't know if its product even exists but a keyboard and mouse duplicator. Say for example you had to do 20 of the same 3 hour long coding sessions to 20 different pies. Then all you have to do is send all of them to be to set up 20 different monitors if you wanted to view all 20 the same time. You might actually want to if 1 out of 20 of the pies run into an error. Or you could just find every single hdmi-compatible monitor in your house save her example 5, then all you have to do is in between each section where there's most likely to be an error if there is going to be an error it would be here and stop coding and check each pie if that is even an issue. II time-saving measure would be. Setting up a flash drive with a button like a slideshow on a projector button. And set up one of those USB hacking devices that can hack advice and set it to download or have remote control over something or whatever you want to do with keyboard and mouse instantly. But whenever you had to stop and check that's what the button would be for. I'm just curious and would love an opinion from anyone who read this.
1. Does it increases speed? 2. How to connect more than onr pls show. I have 20 old dual core PCs in my lab , how can I parallely use these processor. Thank you
Video is awesome. I already knew the circa. procedure^^ Thinking about a virtual cpu emulated over multiple pi's right now. I really like your homour :D
I noticed something that might not be good if you like to stay organized with your Pi! When you created that master img to flash on all the other SD cards, they will all be named Pi01! I guess you can rename it but that might take a while depending on how many of those computers your tying to cluster.
DD is pretty flawed. So I had to install Kali (amd64), Kpartx, and mount a Kali RPi image to it, then use GNOME Partition Manager, create a FAT16 and EXT4 (boot and root, respectively), and then copy the boot files, then clone the root filesystem. It took awhile, but it works.
+Joe Federico look it up, so yes you could make this with pi zeros, oh and if you hack together old junk cables instead of buying new ones +1 to you, you resourceful person.
When can we expect part two? im caught up and keen to keep going!, do you have a list of the commands i need to enter to finish off the worker pi? or other node/nodes
I know this video is old, and this probably is more recent, but instead of changing the inittab file, you could just choose auto login in one of the raspi-config menus
Installing and using Python for a 'super computer' is almost an insult. If you used higher-end language you wouldn't need a super computer. Anyway great video, cant wait to see it running.
I don't know if you are still answering questions on this video, but I might as well try. Can you run programs with GUIs using the cluster, or only python/C++ files?
Question. I keep reading there is no other use for a cluster other than to calculate large equations. Can the cluster be used as a very fast desktop???
Well I was interested in this and thought I may give it a go, but it is on a much higher level of geekieness than I though, still it does look interesting, but I'll stick to building a PC in the usual way.
first of all....great video...really insightful...thank you...want to run Weather Research and Forecasting model based on Fortran , C and Unix she'll commands, is it possible to control raspberry pi's as slave nodes via an Ubuntu desktop??
I am stuck with the following error "configure : error : The Fortran compiler gfortran will not compile files that call the same routine with arguments of different types. ". Can someone help me out ?
He sets GPU memory to 16 because in a cluster like this, you use the cpu for tasks (You won't be playing games or whatever), so the GPU doesnt need the memory. Just always leave it at 16 for clusters basically
