Hi Jerome! Hi Nick!
Thank you very much for sharing your thoughts on our mutual interest. Jerome reasonably asked if I'd looked at Intel's latest drivers. "neo". I had not. But he inspired me to. I'm glad it seems stable. To be fair, though, I don't recall seeing any computer benchmarks from Intel as dramatic as AMD's Radeon VII. The Radeon VII is evidently rated at a theoretical max of 3 trillion 64 bit floating point operations. Per second! The other info I have that may be of interest is for IBM's POWER9 CPUs. I think they may sometimes be fast enough to replace GPUs. My understanding is an 8 core POWER9 CPU has been bench marked at half the speed of a GeForce 980 running cuda. 50 (vs. 100) Gigaflops. The bench mark was a lightly optimized nbody. The author seemed to think gcc supports the POWER9's vectorization pretty well. Up to 44 POWER9 cores are available on mother boards from Raptor Computing Systems. Wouldn't it be nice if POWER9 CPUs were fast enough to run regular python, without rewriting applications to conform to (py)opencl, or a GPU? But, all the above info is hear say. I can't vouch for it personally. Nor do I have any specific reason to doubt it. So, Kingsley On 10/01/2019 11:53, Jerome Kieffer wrote: > On Mon, 30 Sep 2019 21:47:15 -0700 > "Kingsley G.
