--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
That just means they don't provide really helpful information on what they
expand threads to. Can you try:
#include <omp.h>
#include <stdlib.h>
#include <stdio.h>
int
main ()
{
int num_places = omp_get_num_places (), i, j;
printf ("num_places %d\n", num_places);
for (i = 0; i < num_places; i++)
{
int num_procs = omp_get_place_num_procs (i);
int *procs = malloc (num_procs * sizeof (int));
omp_get_place_proc_ids (i, procs);
for (j = 0; j < num_procs; j++)
printf ("%d ", procs[j]);
printf ("\n");
free (procs);
}
return 0;
}
with all the 3 compilers+runtimes and get what it prints for
OMP_PLACES=threads,
OMP_PLACES=cores and OMP_PLACES=sockets on your machine?
