What's the proper way to use shmem_int_fadd() in OpenMPI's SHMEM? A minimal example seems to seg fault:
#include <cstdlib> #include <cstdio> #include <mpp/shmem.h> int main(int argc, char **argv) { shmem_init(); const size_t shared_segment_size = 1024; void *shared_segment = shmem_malloc(shared_segment_size); int *arr = (int *) shared_segment; int *local_arr = (int *) malloc(sizeof(int) * 10); if (shmem_my_pe() == 1) { shmem_int_fadd((int *) shared_segment, 1, 0); } shmem_barrier_all(); return 0; } Where am I going wrong here? This sort of thing works in Cray SHMEM. Ben Bock
