I'm curious about your next gen plans, given Phi's roadmap.

low level HPC means... lots of things. BUT we are a huge Xeon Phi shop and need low-level programmers ie. avx512, careful cache/memory management (NOT openmp/compiler vectorisation etc).
I played around with avx512 in my rzf code. https://github.com/joelandman/rzf/blob/master/avx2/rzf_avx512.c . Never really spent a great deal of time on it, other than noting that using avx512 seemed to downclock the core a bit on Skylake.
Which dev/toolchain are you using for Phi? I set up the MPSS bit for a customer, and it was pretty bad (2.6.32 kernel, etc.). Flaky control plane, and a painful host->coprocessor interface. Did you develop your own? Definitely curious.

My background is C and now JavaScript, mostly online course work and telnet MUDs. Any suggestions are very much needed. What must a "low level HPC" know on day 1???
