mike165 wrote:also, if there are more threads than cores, does OpenMP use the primary threads on each core first? or is that up to the OS to determine which threads of which cores are executed by diff. applications at the same? in general, i would assume that the primary threads on each core are used up first, then if another user tries to run their application, they might get mostly secondary threads? Or are they redistributed?
