Abstract
This paper presents MPFL, an extension to SWFL that provides a message passing flow language for describing parallel scientific applications with message passing composed from Web services. The background to developing the language is discussed. Then the paper focuses on four main message passing issues: communicators, point-to-point communications, collective communications, and application topologies. The semantics of the language and its model for representing message passing are also described.
