I would like to run a hybrid application (CP2K) on the Xeon Phi. The application is MPI + OpenMP and I set up the environment in the following manner: $ export OMP_NUM_THREADS=15 $ export I_MPI_PIN_PROCESSOR_LIST=$(seq -s "," 1 $OMP_NUM_THREADS 240) $ echo $I_MPI_PIN_PROCESSOR_LIST 1,16,31,46,61,76,91,106,121,136,151,166,181,196,211,226 $ mpirun -n $(expr 240 / $OMP_NUM_THREADS) However, the application is running awfully slowly. When I run the "top" command only shows the 16 MPI processes and not any of the threads and says the Phi system is 6.2% user busy (16 / 240 * 100). It seems like the threads are not running. Any help will be greatly appreciated. Thanks in advance
