Explicit Parallel Programming: System Description

The implementation of the Explicit Parallel Programming (EPP) system is described. EPP is a prototype implementation of a language for writing parallel programs for shared memory multiprocessors. EPP may be viewed as a coordination language, since it is used to define the sequencing or ordering of various tasks, while the tasks themselves are defined in some other compilable language. The two main components of the EPP system---a compiler and an executive---are described in this report. An appendix is included which contains the grammar defining the EPP language as well as templates used by the compiler in code generation.
