OMP Warning #205 KMP_AFFINITY: cpuid leaf 11 not supported

I upgraded from v11.1 toXE 2011 Update 4 and the same code that was running fine in v11.1 now gives me this warning:

OMP Warning #205 KMP_AFFINITY: cpuid leaf 11 not supported - decoding legacy APIC ids.

Any idea what this means?

Could you provide a test case of your code that produces this error, and possibly information about your system?

This is not my area of expertise, but my guess is that this is independent of the program. The message would appear to relate to the OpenMP run-time library attempt to determine the CPU configuration so that it can set threa affinity. Are you explicitly setting affinity with the KMP_AFFINITY environment variable? What is your CPU configuration?
