Hardware for Phonix FD

Well, i bought the CPU online as i was not able to build one myself ;).
Fun aside, it’s a E5-2695 v3 ES, that runs a turbo of 3.0 GHz on all cores. And for the RAM, it certainly runs on 2133 as well, my bad. I was confusing it with our “basic” workstations here that are dual 8-core (E5-4650) with 1600 DDR3. The M2 of the dual Xeon is even twice as fast as the one in the i7 build. (~2GB/s write vs. ~1GB/s, iops are roughly equal). So you can compare the systems, and believe me, we did. There seems to be a lot of crosstalk between the cores while simming, also on grid based stuff, what we call the “butterfly effect” here. So at a certain point, diminishing returns from our personal experience. It’s even worse with SPH btw.

I see … Do you have any numbers regarding the speed difference between the two? I am curious to know if the gains are enough to actually consider a separate simulation machine as part of the renderfarm …
