Im looking at creating a cluster out of 3 raspberry pi's with the idea to upgrade the system. Im looking at using the system to run simulations and possibly graphics design software.

 

1) How do I connect 3 raspberry pi's together to create a cluster computer.

   - Im 18 and fairly tech savvy but never tried to create a networking system before. I know whats going on with hardware    but by no means am I a Supernerd with networks.

 

2) Will I be able to add extra raspberries after I've run software on it etc.

It's been done over ethernet before, and that would probably be the best option, considering the relatively low computational power of these.

yeah the power kind of sucks on them but its a little challenge to see how I can build a bigger one over time. money constraints etc.

 

Will I bottleneck my network btw? Ive already got 5 -6 home computers connected to a wifi. Id be buying a new router to do this so id have two routers in the house. I assume because the raspberry pi's are only using the local network they won't slow down computers that are trying to connect to the internet?

You're going to want a switch, not a router. It shouldn't cause any problems. All information should transfer through the switch and not leak over to your internet.

oh ok. Told you I wasn't the best with networking lol. I assume that keeps all the data passing between the raspberry's from being sent over the full network and acts kind of like the old lan gaming (flight sim ftw) connecting 2 computers together?

Pretty much.

 

You might want to practice some networking before you go this path though.

yeah ill defo look at networking before I try doing this. Ill have to get used to linux too. Not my favourite os by far but better for this sort of thing from what I can gather.

I'm thinking everything on RaspberryPi is in linux anyways. Start off with some basics. Run it in a VM and toy with network settings.
