Openmp vs pthread performance comparison
Webstd::thread vs OpenMP A performance comparison of a threadpool built from C++11's std::thread library and the shared-memory parallel programming API OpenMP. Matrix … WebAfter that, we used MPI, OpenMP, Pthread, and OpenCL runtime libraries. Among them, MPI is a parallel program interface based on multiple processes with good performance, which is used in this paper for point-to-point communication between nodes. Both OpenMP and Pthread are thread-parallel interfaces.
