The Message Passing Interface (MPI) standard supports Remote Memory Access (RMA) operations, where a process can read or write memory of another process without requiring the target process to be involved in the communication. This enables new more e

Efforts to mitigate lock contention from concurrent threaded accesses to MPI have reduced contention through fine-grained locking, avoided locking altogether by offloading communication to dedicated threads, or alleviated negative side effects from c

This paper provides an in-depth analysis of the software overheads in the MPI performance-critical path and exposes mandatory performance overheads that are unavoidable based on the MPI-3.1 specification. We first present a highly optimized implement

MPI allows applications to treat processes as a logical collection of integer ranks for each MPI communicator, while internally translating these logical ranks into actual network addresses. In current MPI implementations the management and lookup of
