Using the Parsec environment to implement a high-performance processor farm

Parsec is a parallel programming environment whose goal is to simplify the development of multicomputer programs without, as is often the case, sacraficing performance. We have reconciled these objectives by “compiling” the structure of parallel applications into information to configure each of a small set of communication primitives on a context sensitive basis. In this paper we show how Parsec can be used to implement a high-performance processor farm and compare Parsec and hand-optimized implementations to demonstrate that Parsec can achieve a similar level of pegormance. Extensive static analysis and optimization is necessary to achieve these results. We discuss both the tools which perform these tasks as well as the user integace that provides the necessary declarative structural information. Using the processor farm, we show how Parsec simplifies the task of specifying the structure of a parallel application and improves the result by supporting abstraction, reuse, ana’ scalability.
