One-Sided Communication in RCKMPI for the Single-Chip Cloud Computer

Abstract : One-Sided Communication functions have been defined in the Message Passing Interface standard since version 2. Modern implementations of the interface, such as MPICH2, support One-Sided Communication. This paper presents insights to the MPICH2 architecture and the implementation of One-Sided Communication in its low-level CH3 communication modules. Further, issues for using MPI's One-Sided Communication features on the Single-Chip Cloud Computer are presented and resolved. The paper also presents a comparative scalability study of an example application both on the SCC and on an InfiniBand cluster.
