Openmp and pthread

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. WebPthread is low level implementation and OpenMp is higher level implementation. For example we assembly language and C language. OpenMp do all the stuff by just writing …
