AFAIK it use pthread to work but it create all necessary pthread at startup to avoid creating them at each loop parallelization. It should work properly with pthreads, it wouldn't be packaged with gcc if it wasn't the case. However I didn't test this combination. openmp is really simple to use, easier than programming the same thing with pthreads. You can see examples on wikipedia : http://en.wikipedia.org/wiki/OpenMP The purpose is to do simple parallelization. If you want to write an algorithm which needs modification to support multi-cores, you have to do it yourself with pthreads.
