Abstract
Abstract. Simultaneous use of powerful system components is important for applications to achieve maximum performance on modern clusters. MPI-2 had introduced onesided communication model that enables for better communication and computation overlap. However, studies have shown limitations of this model both in the context of applications and higher-level libraries. As part of MPI-3 effort, the Remote Memory Access group has proposed several extensions to the existing one-sided communication interface to address these limitations. In this paper, we present design, implementation and evaluation of some of the key one-sided semantics proposed for MPI-3 over InfiniBand, using the MVAPICH2 library. 1
