Summary: The 5.0 spec states, "The omp_get_max_threads routine returns an upper bound on the number of threads that could be used to form a new team if a parallel construct without a num_threads clause were encountered after execution returns from this routine." The attached test shows Max Threads: 96, Num Threads: 128 without the proposed change. The number of threads should not exceed the (max) nthreads ICV, hence we should return the higher SPMD thread number even when omp_get_max_threads() is called in a generic kernel. This change does fail the api test, max_threads.c, because now it would return 64 instead of 32.
