MPI is the standard interface for message passing in parallel systems. The standard was defined in an open collaborative forum involving about 60 people from 40 different organisations, and the finished version was completed in May 1994. EPCC and CRI have established a collaboration to develop and support a robust, high performance implementation of MPI for the T3D. The product was released from EPCC in May 1995. In this paper we describe the architecture of MPI for the T3D and present performance measurements of the implementation. It is shown that a significant part of the T3D capability is available through MPI, demonstrating that MPI is capable of delivering both performance and portability to applications. 1 Introduction MPI [5] is the standard interface for message passing in parallel systems. The standard was defined in an open collaborative forum involving about 60 people from 40 different organisations. An initial draft of the standard was released at the Supercomputing '93 ...
