(I am very new with my RPi. It just showed up yesterday! :D As such, sorry if this sounds kind of simple or misinformed)

I have seen many creations online that use 2 or more RPis to make parallel computing platforms.

The first question which needs to be answered is simply:

Is this even possible?

Now, my actual question might be a little vague, but I'll try to make it possible to give a single, solid answer:

What do I need to make two RPis function as a single computer?

Now, I suppose I could split that up into two different questions:

What hardware will I need to buy in order to make two RPis function as a single computer? (connectors, maybe a router if I make them into a sort of server farm? I'm not sure.)


What kind of software am I going to need? Will I need to use a custom OS, or will Raspbian help me with this?

I have a fair amount of programming and computer experience, but have never done anything like this before. Plus, my Google results have been rather ambiguous.


Great to hear you have just recieved your Raspberry Pi! Instructions to set up the Pi's in the format you desire is documented incredibly well at http://www.southampton.ac.uk/~sjc/raspberrypi/pi_supercomputer_southampton.htm by Professor Simon Cox, the man who originally set up the idea.

I hope this helped you and I cannot wait to see what you make with your new equipment.

  • That is perfect! As for my intended projects, I'm going to start with making a Minecraft server. It's simple and easy to set up, and I'm already pretty familiar with it. Eventually I want to turn an array of Pis into a sort of server farm; running a webserver, the aforementioned Minecraftserver, an FTP server, etc. This will be complete with fancy LED displays and stuff. I'm very excited.
