The Real-Time Message Passing Interface Standard (MPI/RT-1.1)

The MPI/RT standard is the product of the work of many people working in an open community standards group over a period of six plus years. The purpose of this archival publication is to preserve the significant knowledge and experience that was developed in real-time message passing systems as a consequence of the R&D effort as well as in the specification of the standard. Interestingly, several implementations of MPI/RT (as well as comprehensive test suites) have been created in industry and academia over the period during which the standard was created. MPI/RT is likely to gain adoption interest over time, and this adoption may be driven by the promulgation of the standard including this publication. We expect that, when people are interested in understanding options for reliable, QoS-oriented parallel computing with message passing, MPI/RT will serve as a foundation for such a study, whether or not its complete formalism is accepted into other systems or standards. MPI/RT is an offshoot of MPI-1, and retains many of the communication patterns of MPI1. However, MPI/RT has investigated issues of fine-grain concurrency and highest achievable ∗Corresponding author: [email protected]. †Presently with D. E.
