Abstract

This paper addresses functionality and implementation of a HPJava version of the Adlib collective communication library for data parallel programming. We begin by illustrating typical use of the library, through an example multigrid application. Then we describe implementation issues for the high‐level library. At a software engineering level, we illustrate how the primitives of the HPJava language assist in writing library methods whose implementation can be largely independent of the distribution format of the argument arrays. We also describe a low‐level API called mpjdev, which handles basic communication underlying the Adlib implementation. Finally we present some benchmark results, and some conclusions.
