Abstract

In this paper we present ALDIMS, a language that combines the expressibility of general functional (MIMD) parallelism with compact expressibility of data (SPMD) parallelism. It uses distributed data structures for specifying data partitions and single assignment variables as abstract means of inter-process communication. Constructs for unstructured parallelism and process placement specifications make general MIMD parallelism expressible. We describe the issues of implementing process invocation and communication primitive generation. We also discuss source level parallelization and optimization issues and strategies.

本文提出了一种将通用函数并行性(MIMD)的可表达性与数据并行性(SPMD)的紧凑可表达性相结合的语言ALDIMS。它使用分布式数据结构来指定数据分区,并使用单个赋值变量作为进程间通信的抽象手段。非结构化并行性的构造和进程放置规范使一般的MIMD并行性可表达。我们描述了实现流程调用和通信原语生成的问题。我们还讨论了源级并行化和优化问题和策略。
