class fill_identity_instruction

Declaration

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

Description

Fills an allocation with the identity value of a reduction. Used as a predecessor to gather_receive_instruction to ensure that peer nodes that do not contribute a partial reduction result leave the identity value in their gather slot.

Inherits from: implement_acceptor

Member Variables

reduction_id m_rid
