                    int source_offset,
                    int destination_processor,
                    int destination_offset,
                    int length)

DRMA Put instruction. Copies 'length' elements from input array (elements are added according to the order the iterator returns), excluding the first 'source_offset' elements, and adds them to this array, local to the destination processor, starting at this[distination_offset].
This instruction buffers the to-be copied current elements here; array elements thus are free to change after calling this put operation.

Note that the copied element will be available at the destination only after synchronisation.

Parameters:

source - Source array.

source_offset - Copy length items beginning at source[ source_offset ].

destination_processor - Target processor ID of this put instruction.

destination_offset - Put items into destination starting at destination[ destination_offset ].

length - Put a total of length items.
