A SERIAL subprogram may contain references to any HPF_LIBRARY procedure or HPF intrinsic function, except HPF_ALIGNMENT, HPF_DISTRIBUTION or HPF_TEMPLATE. Within a SERIAL scope the HPF_LOCAL_LIBRARY module must not be used.
References to the intrinsic functions NUMBER_OF_PROCESSORS and PROCESSORS_SHAPE will return the same value as if the function reference appeared in global HPF.
