Assuming the DAP CentOS install is using the normal CentOS repos you should be able todo a normal "yum update" to get to 7.3. 7.3 kernel is around 3.10.0-514.6.1.el7.x86_64 currently. Ensure the kernel isn't excluded in /etc/yum.conf. Grab XPPSL 1.5 from Intel and install it per its instructions. Ben

Mike,

I am free from now until 11 am, and then after lunch 1 pm.

Jeff,

Good question. I have two Linux kernels on the DAP box. For some of the QMCPACK benchmarks, I seem to get a lot of Vtune over head with the MPSP kernel. When I used the default CentOS kernel, I don’t see this problem. I have managed by rebooted between kernels, but its kind of a nuisance.

Hi Nick,

Let me know when you want to get this done. Except for a few meetings, I will be in 240 all day.

Stupid question: Why do you want to do this?

There are probably many things you want to watch out for. Mike D'mello should be able to get you details in any case.

I would like to update my DAP box with the latest kernel. (DAP box is running CentOS 7.2). https://software.intel.com/en-us/articles/xeon-phi-software

I am assuming this is relatively straight forward install? Or is there something that I should watch out for?

The free list sort patch for Linux is really important. Please test it like crazy and let us know if there any major regressions.

Intel's XPPSL (MPSP) has been updated to 1.4.1. The KNL nodes will get the updates on their next reboot.

Intel included a new kernel module to help deal with the cached memory mode performance degradation over time issue named zonesort_module. See page 21 in the attached doc.

Note, I plan on loading this module and running "echo 0 > /sys/kernel/zone_sort_free_pages/nodeid" on job start where the node is not rebooted, and the mode is cached. If someone is interested in testing this out before I get to implementing it, let me know.

Interesting known issues:

- The hbmalloc library does not guarantee to allocate memory from the closest MCDRAM node when SNC-2 or SNC-4 Memory Mode is used.
