Metacomputing infrastructures couple multiple clusters (or MPPs) via wide-area networks. A major problem in programming parallel applications for such platforms is their hierarchi...
This paper examines the explicit communication characteristics of several sophisticated scientific applications, which, by themselves, constitute a representative suite of publicl...
One of the most important collective communication patterns used in scientiļ¬c applications is the complete exchange, also called All-to-All. Although efļ¬cient algorithms have b...
