| Here's your answer for GROMACS (and it sucks)... http://www.prace-ri.eu/IMG/pdf/wp120.pdf Even so, right now, little would please me more technologically than a competitive Xeon Phi offering, but while KNL is better than KNC, my inside info says it sucks too (it would have been a lot more interesting, just like Altera's Stratix 10, if it had shipped before GP100 and GP102). Right now, I have more confidence in AMD GPUs right now than I have in Xeon Phi. This 3rd party benchmark is particularly interesting (and it doesn't look like anyone at NVIDIA is paying any attention to it): https://techaltar.com/amd-rx-480-gpu-review/2/ Sure, NVIDIA is still in the lead, but not with the ~10x margins they used to have over AMD. Finally, I figuratively feel like punching the next person who makes the BS scaling argument over raw performance. GPUs scale too if they're coded correctly. And cloud datacenters are the worst place for that given their craptastic ~10 Gb/s interconnect subject to arbitrary network weather effects. Or butchering Seymour Cray: Your life depends on winning a race, would you bet your life on a 1,350 HP Venom GT or on 20 179 HP Scion FRSs? I mean collectively that's almost 3600 HP, right? Except it's even worse because for GPUs vs CPUs, it's like they priced the Scion FRS like a Venom GT and vice versa. I wish you luck finding Xeon Phi winning anything but synthetic tests against yesterday's news: https://www.xcelerit.com/computing-benchmarks/libor/intel-xe... |
