Optional argument. PROC.
Description.
Returns the highest local index of all blocks of an array dummy argument
in a given dimension on a processor.
Class. Pure function.
Arguments.
ARRAY may be of any type; it must be a dummy array that is associated with a global HPF array actual argument.
DIM must be scalar and of type integer with a value in the range , where is the rank of ARRAY.
PROC (optional) must be scalar and of type integer.
It must be a valid processor number.
Result Type, Type Parameter, and Shape.
The result is a rank-one array of type default integer
and size , where is the value returned by
LOCAL_BLKCNT(ARRAY, DIM [, PROC])
Result Value.
*
(i): The value of LOCAL_UINDEX(ARRAY, DIM, PROC) has a value whose th component is the local index of the last element of the th block in dimension DIM of ARRAY on processor PROC.
(ii): LOCAL_UINDEX(ARRAY, DIM) returns the same value as LOCAL_UINDEX(ARRAY, DIM, PROC=MY_PROCESSOR()).
Examples.
With the same declarations as in the example under LOCAL_BLKCNT,
on the physical processor corresponding to PR(2,4) the value returned by
LOCAL_UINDEX(X, DIM=1) is ,1,2,3,4,, plus 1filll
-1;1,2,3,4,; plus 1filll
-1:1,2,3,4,: plus 1filll
-1.1,2,3,4,. plus 1filll
-11,2,3,4, plus 1filll-1; the value of
LOCAL_UINDEX(X, DIM=2) is ,2,3,4,, plus 1filll
-1;2,3,4,; plus 1filll
-1:2,3,4,: plus 1filll
-1.2,3,4,. plus 1filll
-12,3,4, plus 1filll-1.
