HI,

We have just bought our first 2 Xeon Phi and I am working on installing them on a SUSE* Linux* Enterprise Server SLES 11 SP2 kernel 3.0.13-0.27-default. I am having a problem find out what my steepings is. THe steppings ID says 3, is that C0?

The coprocessor stepping

The coprocessor stepping field appears just a little further down. It is: Coprocessor Stepping : B1

You have two B1 cards, not C0.

I’m not 100% certain about the Coprocessor Stepping ID mapping to the Coprocessor Stepping, but cards I can access reflect the following:

Coprocessor Stepping : Coprocessor Stepping ID

B0 : 1
B1 : 3
C0 : 2

Thank you, I guess I missed
