Description. Returns the number of elements of the ultimate
align-target of ARRAY mapped to the each element of
axis PROCESSORS_DIM of the processors arrangement onto which
the ultimate align-target of
ARRAY is distributed.
Class. Mapping inquiry subroutine.
Arguments.
ARRAY may be of any type. It must not be scalar. It must not be sequential. It must not be a pointer that is disassociated or an allocatable array that is not allocated.
PROCESSORS_DIM must be scalar and of type default integer. Its value must be between one and the rank of the processors arrangement onto which the ultimate align-target of ARRAY is distributed.
NUMBER_MAPPED must be of type default integer and of rank one. Its size must be no smaller than the extent of axis PROCESSORS_DIM of the processors arrangement onto which the ultimate align-target of ARRAY is distributed. The ith element of NUMBER_MAPPED is set to the number of elements of an axis of the ultimate align-target of ARRAY that are mapped to the ith processor of axis PROCESSORS_DIM of the processors arrangement onto which the ultimate align-target of ARRAY is distributed. If axis PROCESSORS_DIM of the processors arrangement onto which the ultimate align-target of ARRAY is distributed is associated with a BLOCK distributed axis, then MAP_ARRAY is set to the array of block sizes used to distribute that axis.
Example. Given the declarations
DIMENSION A(2,40) !HPF$ TEMPLATE T(4,8,4,16) !HPF$ ALIGN A(I,*) WITH T(2*I, 5, *, *) !HPF$ PROCESSORS PROCS(2,2,3) !HPF$ DISTRIBUTE T(INDIRECT((/2,2,1,2/)), BLOCK((/3,5/)), *, BLOCK) & !HPF$ ONTO PROCS
assuming that the actual mappings are as the directives specify, after calling HPF_NUMBER_MAPPED(A,PROCESSORS_DIM=1, NUMBER_MAPPED = M) M has the value [1 3]; after calling HPF_NUMBER_MAPPED(A,PROCESSORS_DIM=2, NUMBER_MAPPED = M) M has the value [3 5]; after calling HPF_NUMBER_MAPPED(A,PROCESSORS_DIM=3, NUMBER_MAPPED = M) M has the value [6 6 4].
