Implementation of Converse InteroperableParallel Programming Environment on ParsytecCC

Asynchronous message handling is an approach to reduce communication delays in message passing parallel architectures. Converse is an interoperable parallel programming environment which combines asynchronous message handling and user level scheduler. It supports message-driven style of programming where messages trigger computations as opposed to explicit receive of messages in traditional message-passing programming. In this paper, we discuss an eecient implementation of Converse environment on Parsytec CC distributed memory machines and present performance results of a few collective communication operations implemented in message-driven (using Converse) and in message passing styles.
