Abstract

Introduction In [PP93] we described a transformational approach to realizing architecture independent parallel execution of a high-level parallel language. Detailed in that document is a series of steps that when applied to highlevel, data-parallel programs written in the Proteus programming language yield parallel execution on a variety of different parallel architectures. The Data Parallel Library (DPL) directly supports Proteus by supplying a vital link in the transformational execution system. 1. DPL - Description and Requirements The Data Parallel Library is a collection of C-callable routines that provide the capability to treat nested sequences as a primitive type. DPL supports data-parallelism by allowing each operation to be applied in parallel to a sequence of inputs yielding a sequence of results. The library contains a wide variety of functions, from the simple display of nested sequence characteristics to complex multi-level indexing of nested seque
