SYNOPSIS
call co_broadcast(a, source_image [,stat] [,errmsg] )
CHARACTERISTICS
DESCRIPTION
CO_BROADCAST(3) copies the value of argument A on the image with image index source_image to all images in the current team. A becomes defined as if by intrinsic assignment. If the execution was successful and STAT is present, it is assigned the value zero. If the execution failed, STAT gets assigned a nonzero value and, if present, ERRMSG gets assigned a value describing the occurred error.
OPTIONS
o A : INTENT(INOUT) argument; shall have the same dynamic type and type parameters on all images of the current team. If it is an array, it shall have the same shape on all images. o SOURCE_IMAGE : a scalar integer expression. It shall have the same the same value on all images and refer to an image of the current team. o STAT : (optional) a scalar integer variable o ERRMSG : (optional) a scalar character variable
EXAMPLES
Sample program:
program demo_co_broadcast implicit none integer :: val(3) if (this_image() == 1) then val = [1, 5, 3] endif call co_broadcast (val, source_image=1) print *, this_image(), ":", val end program demo_co_broadcast
