Yes; I tried a Xeon Phi. And I reported my experience as:<p>I wanted to treat the Xeon Phi like a regular Xeon with just many more cores. So I ran my benchmark mostly unchanged. I was surprised however that the single threaded performance was roughly 20x lower than a normal Xeon.
Using all 240 threads I was still doing no better than with 12 cores on a normal Xeon. It seems that the Xeon Phi memory subsystem is not really optimized for multithreaded random access.<p>The provider of that system suggested that I ought to perform computation and memory access (including prefetching) on the SIMD units (VPUs), but
I haven&#x27;t gotten around to studying the use of VPUs yet...
