I can't use OpenMP! Will it be possible, in the new version of Fortran, to move this calculation into a GPU with, lets say, 5000 cores. This should mean that each core could calculate one matrix element. As I understand it this should require that each core in the GPU has a reserved memory area or am I wrong?&nbsp; The amount of data allocated to each core for the calculations is rather small. Will the memory data transfer to the GPU and/or the MPI overhead to collect the calculated matrix elements kill this use of the GPU?</P> <P>Best regards</P> <P>Anders S</P> Sun, 19 Dec 2021 17:07:45 GMT Anders_S_1 2021-12-19T17:07:45Z https://community.intel.com/t5/Intel-Moderncode-for-Parallel/Can-an-MPI-task-be-moved-from-a-CPU-to-a-GPU-in-oneAPI-Fortran/m-p/1345219#M8179 <P>Hi,</P> <P>I am presently running Fortran with MPI under WIN10 to calculate typically 5000 matrix elements using 60 threads during each iteration step.
