Installing MPSS

Karan_S_ · ‎04-17-2014

All,

I Recently obtained a xeon-phi and I have been trying to install it. I have centos 6.5. I followed the instruction and installed the mpss service using yum install MPSS. After installing, i do lsmod | grep mic and I can see the mic. Furthermore, I can see xeon phi in lspci -vv

Can someone help me out. Am i doing something wrong ?

Hi Karan,

You are using a non-supported OS. This just means that we don't validate against it. Plenty of people use Centos without issue.

Have you recompiled the kernel module for use with Centos?

The pre-built MPSS for RHEL 6.5 should work on CentOS 6.5 x86_64 if the BIOS is compatible with the right settings.

Tim,

You took the wind right out of my sails. If the BIOS doesn't support memory mapped I/O >4G, you need to update your BIOS.

You can find a lot more information about what type of BIOS upgrades you need by searching software.intel.com.
