Openmp mpi pthread对比

WebThe NSLOTS variable which is required to set the total number of slots/cores for the parallel environment -pe mpi is usually the number of MPI tasks multiplied by the number of OpenMP threads per task. In this example the number of MPI tasks is 11 and number of OpenMP threads per task is 16, so 176 slots are required. Job array example ¶ http://www.diva-portal.org/smash/get/diva2:944063/FULLTEXT02
