Abstract

In this paper, we study the exchange of messages among a set of processors linked through an interconnection network. We focus on general, non-unimiform versions of all-to-all (or complete) exchange problems in asynchronous systems with a linear cost model and messages of arbitrary sizes. We extend previous complexity results to show that the general asynchronous problems are NP-complete. We present several approximation algorithms and determine which heuristics are best suited to several parallel systems. We conclude with experimental results that show that our algorithms outperform the native all-to-all exchange algorithm on an IBM SP2 when the number of processors is odd.
