摘要

The latest version of the Portals interconnect programming interface contains several improvements intended for MPI point-to-point and one-sided communication operations, including new functionality defined in MPI-3. This paper discusses the rationale for these improvements to Portals and describes how they can be used in an MPI implementation. We provide preliminary micro-benchmark performance results using a reference implementation of Portals over InfiniBand Verbs and the Open MPI implementation.
