I don't know if this applies her but I seem to recall an issue with CentOS 7 (newer 3.X and on kernels), Broadwell processors and GPFS where GPFS upset SMAP and would eventually get the node expelled. I think this may be fixed in newer GPFS releases but the fix is to boot the kernel with the nosmap parameter. Might be worth a try. I'm not clear on whether SMAP is supported by the Xeon Phi's. -Aaron On Wed, Dec 7, 2016 at 5:34 AM <david_johnson at brown.edu> wrote: > IBM says it should work ok, we are not so sure.
