Abstract

We describe an architecture for the runtime environment for parallel applications as prelude to describing how parallel application might interface to their environment in a portable way. We propose extensions to the Message-Passing Interface (MPI) Standard that provide for dynamic process management, including spawning of new processes by a running application and connection to existing processes to support client/server applications. Such extensions are needed if more of the runtime environment for parallel programs is to be accessible to MPI programs or to be themselves written using MPI.
