A variety of projects worldwide are developing what we call "heterogeneous MPI". These MPI implementations are designed to operate on multiple computers, perhaps of different types, ranging in complexity from a set of desktop workstations to several supercomputers connected via a wide area network. These considerations led us to investigate the feasibility of defining a common API that could be used within MPI implementations to access process startup, initialization, monitoring, and control functions provided by an underlying process management system. If various MPI implementations coded to that API, one could then develop multiple "process management" modules that could be reused within different MPI implementations, thus allowing partitioning of effort between different development groups. In pursuit of this goal, we have designed such an API, which we call BNR. The major goals of the BNR interface are outlined
