One-sided Communication on the Myrinet-based SMP Clusters using the GM Message-Passing Library

Introduction In the past five years, the Myrinet network has received much attention in the literature on high-performance communication. Multiple projects have focused on developing efficient messaging middleware (e.g., AM[1], PM[2], BIP[3], and HPVM FM [4]) by exploiting the programmable network interface card (NIC) of Myrinet. The most common use of these interfaces has been support of MPI and other internal research projects. The HPVM project used its FM system to implement MPI and other programming interfaces including two one-sided: the Cray SHMEM and Global Arrays. In the last few years, because of the good scalability and rather moderate cost, Myrinet has become the primary network for building medium and large-scale clusters based on commodity processing nodes (e.g., Intel or Alpha Linux systems). To our best knowledge, with the exception of the NCSA Windows NT SuperCluster that operates in the HPVM environment, the majority of medium and large Myrinet-based clusters used i
