Abstract

We describe the use of MPI for writing system software and tools, an area where it has not been previously applied. By “system software” we mean collections of tools used for system management and operations. We describe the common methodologies used for system software development, together with our experiences in implementing three items of system software with MPI. We demonstrate that MPI can bring significant performance and other benefits to system software.
