MPI: A Message-Passing Interface Standard第三版

This document describes the Message-Passing Interface (MPI) standard, version 3.1. The MPI standard includes point-to-point message-passing, collective communications, group and communicator concepts, process topologies, environmental management, process creation and management, one-sided communicat

Overlappingcomputationwithcommunicationisakeytechniquetoconceal the effect of communication latency on the performance of parallel applications. Message Passing Interface (MPI) is a widely used message passing standard for high performance computing. One of the most important factors in achieving a good level of overlap is the MPI ability to make progress on outstanding communication operations. In this paper, we propose a novel speculative MPI Rendezvous protocol that uses RDMA Read and RDMA Write to effectively improve communication progress and consequently the overlap ability. Performance results based on a modiﬁed MPICH2 implementation over 10-Gigabit iWARP Ethernet reveal a significant (80–100%) improvement in receiver side overlap and progress ability. We have also observedupto30%improvementinapplicationwaittimeforsomeNPBapplications as well as the RADIX application. For applications that do not beneﬁt from this protocol, an adaptation mechanism is used to stop the speculation to effectively reduce the protocol overhead.
