I'm assuming that EM simulations are massively parallel. Depending on your budget you should consider a threadripper or the new Intel HEDT for a budget option.

- mastax 7y agoThere's also regular ryzen with up to 16 cores and 128GB of RAM.
- madengr 7y agoSee my other reply. Ryzen is 30% slower due to Intel compiler optimizations, and I need higher clock speed rather than cores. The new i9 with 5.1 GHz boost should work best.
- madengr 7y agoThat’s the problem. They are not massively parallel. In fact, don’t use more than two cores efficiently. Therefore the i9 will perform better than Xeon due to higher clock speed with lower cores. Also, this software uses Intel MPI libraries. A new i7 runs it 30% faster than a new Ryzen 7 with same clock speed. So Intel is tweaking their compiler for their processors.
