This paper presents McMPI, an entirely new MPI library written in C# using only safe managed-code, and performance results from low-level benchmarks demonstrating ping-pong latency and bandwidth comparable with MS-MPI and MPICH2.McMPI enables all .Net languages to use MPI messaging without introducing a dependency on unsafe non-managed code, e.g. an existing MPI library. It also takes advantage of .Net thread support to improve intra-node latency.This paper also discusses support for multiple threads in McMPI and proposes an extension to the MPI Standard that resolves current ambiguities relating to hosting multiple MPI processes in a single operating system process.
