478件の閲覧回数 I've come across a situation that I need to perform a equivalent of mpi_allreduce (mpi_allgather would suffice) in Coarray application. At first, i trying co_sum() collective, but I was suspecting that it was very slow (VTune pointed ou...

the full performance benefit from these improvements in processor technology, applications need to take advantage of both forms of parallelism. This article will focus on SIMD parallelism; multi-core parallelism is addressed elsewhere, with both OpenMP* and MPI being widely used in Fortran applications...
