[gpfsug-discuss] Any experience running native GPFS 4.2.1 on Xeon Phi node booted with Centos 7.3?

[Aaron Knister]

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.
