OpenSHMEM is an open standard that brings together several long-standing, vendor-specific SHMEM implementations that allows applications to use SHMEM in a platform-independent fashion. Several implementations of OpenSHMEM have become available on clusters interconnected by InfiniBand networks, which has gradually become the de facto high performance network interconnect standard. In this paper, we present a detailed comparison and analysis of the performance of different OpenSHMEM implementations, using micro-benchmarks and application kernels. This study, done on TACC Stampede system using up to 4,096 cores, provides a useful guide for application developers to understand and contrast various implementations and to select the one that works best for their applications.
