[Omp] [OMP] Can I mix OMP with pthread in a code?

[Meadows, Lawrence F]

Mixing OpenMP and pthreads depends on your vendor. The Intel compiler
supports it.
 
The performance problem is probably not related to mixing pthreads and
OpenMP, it sounds like -mp may be disabling some optimizations; but
you'd have to check with your compiler vendor.

Dear All,

Can I mix OMP with pthread in a code? 
Well the answer might be yes, but with PathScale EKOpath V.2.5, I see
the performance on my pthread code drop to near serial when OMP flag
(-mp) is on, but the OMP code still run fine.  Any recommendation on
OMP/pthread mixing, or should I stay with pure OMP or pure thread.

Thank you very much.
