I have Xeon Phi 7210 processor in the node that I am using. I am running Ubuntu 14.04 and followed the guide:
But even after following the steps, miccheck doesn't detect the Phi.

Can someone help me fix the issue.
that guide is for the first Xeon Phi generation, code named Knight's Corner (KNC); yours is the second gen, Knight's Landing (KNL) which does not need any special drivers - it is just a many-core CPU. No special software needs to be installed.
