Hello, I need to build a computer which will specifically be for running physics simulations. It needs to have a lot of processors / cores and RAM (cores are more important however).
Apart from a large hard drive, it doesn't need anything else, no graphics card or anything like that. It just has to be fast and parallel since the codes used can exploit this fully. I can't seem to find many dual or quad processor motherboards.
As an aside, nearly every computer system I've used for such a task has generally been an intel system (usually Xeons, but I'm running the code on my laptop, which is an i5 2520m as well). Is there any reason to ignore the hex core and octa core AMD processors? Are they not as fast when it comes to IFORT compiled software? There's quite a lot of flags in the IFORT compiler which specifically target intel hardware so it would make sense (gcc is too slow compared to IFORT).
Thank you
