Title: X-SRQ - Improving Scalability and Performance of Multi-Core InfiniBand Clusters
Author(s): Galen M. Shipman, Stephen Poole, Pavel Shamis, and Ishai Rabinovitz
Abstract:
X-SRQ is a new transport protocol in Open MPI based on B-SRQ which
takes advantage of this improvement in connection scalability. This paper
introduces the X-SRQ protocol and details the significantly improved
scalability of the protocol over B-SRQ and its reduction of the memory
footprint of connection state by as much as 2 orders of magnitude on
large scale multi-core systems. In addition to improving scalability, performance
of latency-sensitive collective operations are improved by up to
38% while significantly decreasing the variability of results.
