Rebooting the box now. It appears on warm reboot, it often hangs or takes an extremely long time for the kernel to boot. With a ipmitool power cycle, it boots normally.

After the machine is back up you're free to test.

Hi Ben,

just talked to Kevin about STREAM - he suggests me to try it as well. The knl.txt says you own it until 5 pm.

Getting the updated jemalloc and memkind libraries would be worth it if we are going to test the flat mode. It might be interesting to get and run the STREAM test in the micperf package to demonstrate the memory bandwidth seems to be incorrect.

The document doesn't really go into what the kernel changes were other than vague statements of fixes or support of additional features.

Intel has a patched RHEL7.2 kernel and a number of other tools that appear to better support KNL. Attached the user guide. Let me know if I should install this on knl00.
