"They need to build libhwloc.so with -static-intel" was the response I got. If you dislike warnings, you can add "-no-intel-extensions" to silence the warning about the Cilk runtime not being statically linkable. Best, Jeff On Tue, Jan 17, 2017 at 10:32 AM, Jef

You need to cross-compile binaries for Knights Corner (KNC) aka Xeon Phi 71xx if you're on a Xeon host. KNC is x86 but the binary format differs, as your analysis indicates. You can either ssh to card and build native, build on host with k1om GCC tool chain, or build on host with Intel

eneck in any application? Are there codes bindings memory frequently? Because most things inside the kernel are limited by single-threaded performance, it is reasonable for them to be slower than on a Xeon processor, but I've not seen slowdowns th

I am inclined to think the issue us that ion Linux uses only 16 cores. When hwloc does n-- for CNK to skip the 17th (OS) core, it gets the wrong answer for Linux. Just check for Linux support and use /proc/cpuinfo and don't adjust manually. I'm not sure hwloc on BGQ ion ion needs and special
