When trying to profile some OpenMP code using "Intel Parallel Amplifier 2011 Update 1, (build 127928)", in Studio 2008, Windows XP 64,
I am getting.....
OMP: Error #134: Cannot set thread affinity mask.
OMP: System error #87: The parameter is incorrect.
OMP: Error #134: Cannot set thread affinity mask.
OMP: System error #87: The parameter is incorrect.
And the profile operation stops at that point.
The code runs fine outside of Amplifier.
I am not trying to set affinity flags in my code , it is "vanilla omp"
I do not have any KMP_ variables set.

Hello,
Could you please provide some more info about the problem:
- Is the issue seen when application runs from Amplifier only? Is there a problem if it is started standalone?
- Please set environment variables KMP_SETTINGS=1 and KMP_VERSION=1. Than reproduce the issue. There should be more detailed error output.
- Can you attach a reproducer sample? Well try to reproduce it in our lab.

Two more questions:
What compiler do you use: MSVS of Intel?
And do you use Intel openMP runtime? If Microsoft compiler is used, Intel openMP should be explicitly set.
Regards,
Kirill
