Automatic Support for Data Distribution

Abstract

A bst rac t I n current automatic parallelizlation systems for distributed-memory machines, the user must explicitly specify how the d a t a domain of the :iequential program is t o be partitioned and mapped to the processors. I n this paper, we outline the salient features of a new knowledge-based software tool that provides automatic support f o r this task. The basic guidelines f o r the design of the tool are discussed, and its major components are described.
