IIRC we added built-in OpenMP support in 10.4; it was available from 3rd
parties prior to 10.4. See:

This really depends on the problem you are trying to solve... FYI: OpenMP is
built on pthreads so I don't think you'll see better thread performance but
you might see better IPC and/or signaling. Overall I think that it's there
for compatibility more than anything else (YOMV ;-).
