Any idea how they perform on a system running in native mode (I took that to mean "running on Phi alone, like a GPU.")? We are currently looking at some pretty aggressive pricing on some Phi cards and are weighing options.

Hi Ryan,
Perri is in the process of writing a paper to describe the Xeon Phi work and will then put together a webpage on it which will have performance numbers etc. For now you get roughly about a 10 to 15% boost in performance, for >400K atoms, by adding a Xeon Phi to a couple of 8 core CPUs.
All the best
Ross

Thanks for your reply.
The one is basically a snippet of the documentation that I had read,
and the other is the mention of MIC/Phi support, which I knew from the
documentation. Did I miss benchmarks or at least a ballpark of
performance compared to a CPU or GPU?
Thanks!

Has there been any update on Xeon Phi support in Amber? I have
read the section of the manual that explains how it is
configured, and the mention of adding support on the website. But
that same section mentions that benchmarks are forthcoming. I'm
wondering if anyone has a rough idea of how they compare in
performance to the other stuff that is out there (Kepler, CPU,
etc.).
