Mapping to Processor Subsets

H806 extended-dist-target

is processors-name [ ( section-subscript-list ) ] or * processors-name [ ( section-subscript-list ) ] or *

• The section-subscripts in the section-subscript-list may not be vector-subscripts and are restricted to be either subscripts or subscript-triplets.
• In the section-subscript-list, the number of section-subscripts must equal the rank of the processor-name.
• Within a DISTRIBUTE directive, each section-subscript must be a specification-expr.
• Within a DISTRIBUTE or a REDISTRIBUTE directive, if both a dist-format-list and a dist-target appear, the number of elements of the dist-format-list that are not ``*'' must equal the number of subscript-triplets in the named processor arrangement.
• Within a DISTRIBUTE or a REDISTRIBUTE directive, if a dist-target appears but not a dist-format-list, the rank of each distributee must equal the number of subscript-triplets in the named processor arrangement.

• If either the dist-format-clause or the dist-target in a DISTRIBUTE directive begins with ``*'' then every distributee must be a dummy argument, except if the distributee has the POINTER attribute.

• If the align-spec in an ALIGN directive begins with ``*'' then every alignee must be a dummy argument, except if the alignee has the POINTER attribute.

• An inheritee must be a dummy argument, except if the alignee has the POINTER attribute.
