PEMPI-from MPI standard to programming environment

The Message Passing Interface (MPI), as an effort to unify message passing systems to achieve portability, defines a widely used standard for writing message passing programs. But MPI alone operates on a rather system-oriented level and does not provide higher abstractions that are mandatory when developing large scale message passing applications. As a result, a programming environment is necessary that not only addresses MPI but also provides programmer oriented abstractions for the core problems of parallel programs, i.e. the management of process, data and communication. We present our on-going approach-PEMPI, an integrated programming environment based on MPI, in which a programmer can obtain portability by employing the MPI standard; achieve performance through machine best-fit implementation; and increase programmability by exploiting higher abstractions based on the Basel Algorithm Classification Scheme (BACS).<
