Multiple Raspberry Pis to Make nicer computer

[TacoMike]

So the new Raspberry Pi 2 just came out and it has all sorts of awesome features like a 900 MHz CPU and 1 GB of RAM, but could I attach two and have a 1.8 GHz CPU and 2 GB of RAM? If so, what would stop me from putting 10 together and making a 9 GHz CPU with 10 GB of RAM?

I hope this is a troll post.......if you put 2 CPUs next to each other what happens? You have 2 CPUs sitting next to each other that's what. They don't just suddenly form Voltron and become one.

What would stop you? Compatible hardware capable of supporting such a setup. Even then if you could somehow have multiple CPUs on the same die.......( yeah they do that already and have since 2006 ) you would have however many cores running at 900Mhz not one super core.

Hey man, I was just asking a question, no need to be a jerk. I was just thinking that you could maybe use some sort of attachment that made it possible, considering the sheer number of kits that people have made for the RP2. I get that it would act as two 900 MHz CPUs and not one big one, I was thinking that it would work with the same "power" as a 1.8 GHz CPU.

OK apologies then. Multiple cores are not additive like that. A multicore CPU with 10 cores at 1Ghz each don't make a 10Ghz CPU it just has 10 cores that distribute the workload.

Yes, you can certainly do this if you are prepared for a little work and learning. Read this link and then Google "Beowolf Cluster": http://www.zdnet.com/article/build-your-own-supercomputer-out-of-raspberry-pi-boards/

Thats awesome!
