num_images(3f) - [FORTRAN:INTRINSIC:COLLECTIVE] Number of images
result = num_images(distance, failed)
Returns the number of images.
DISTANCE (optional, intent(in)) Nonnegative scalar integer FAILED (optional, intent(in)) Scalar logical expression
Scalar default-kind integer. If DISTANCE is not present or has value 0, the number of images in the current team is returned. For values smaller or equal distance to the initial team, it returns the number of images index on the ancestor team which has a distance of DISTANCE from the invoking team. If DISTANCE is larger than the distance to the initial team, the number of images of the initial team is returned. If FAILED is not present the total number of images is returned; if it has the value .true., the number of failed images is returned, otherwise, the number of images which do have not the failed status.
Sample program:
program demo_num_images implicit none integer :: value[*] integer :: i value = this_image() sync all if (this_image() == 1) then do i = 1, num_images() write(*,(2(a,i0))) value[, i, ] is , value[i] end do endif end program demo_num_images
