Declaration

class gather_receive_instruction : public implement_acceptor { /* full declaration omitted */ };

Description

A special type of receive instruction used for global reductions: Instructs the receive arbiter to wait for incoming transfers of the same region from every peer node and place the chunks side-by-side in a contiguous allocation. The offset in the output allocation are equal to the sender node id.

Inherits from: implement_acceptor
