WebAnswer (1 of 2): No. OpenMP was not developed with SIMD in mind. OpenMP did not include SIMD support until V4.0. Both OpenMP and pthread do parallelism within the process. (MPI works between processes on the same or different machines.) Why or when to use one over the other. * pthread: Use it...
