Dual Opteron for maths?

Orangezorki · July 4, 2014

Hello all,

I'm doing some maths problems with a C program that I've written that uses multiple cores. At the moment I'm using OSX on a i7-2700k system I built about three years ago. It's actually a great system, but not churning through the massive amounts of data that I am getting through. For the current problem I have it set to, it's been run for about 10 days on a single thread and I wouldn't be surprised if it took a couple of years at least to complete.

So, I need multi-core, and I think I have just managed to get a multi threaded version of my app running. But the i7 is just 4 cores with 8 threads, and I think I can do much better. So it might be time to build a new system. OSX is not necessary - linux will be fine. I use no floating point, and I understand that AMD is more competitive on integer processing than overall benchmarks might suggest. So I'm drawn to the possibility of a dual opteron system with 32 cores. The processors just seem so cheap in comparison with Intel - we're talking about three times the number of cores for the money.

However, I can't find much info at all on the 6300 opterons. Am I missing something?

Wish I could help you on this but since I can't I'll send you somewhere where people can.

All the cores eh?

Can I ask what the maths is for?

~~If you can find those new will probably outperform the opterons with less power consumption~~

**EDIT it's for integer not float, maybe the opterons are a good idea. I'll let someone with more knowledge adivse you as I'd hate for you to waste a lot of money But the 6370P looks like good value.
