Abstract
The objective of this paper is to develop models that characterize the communication performance of a messagepassing multicomputer by taking the IBM SP2 as a case study. The paper evaluates and models the three aspects of the communication performance: scheduling overhead, message-passing time, and synchronization overhead. Performance models are developed for the basic communication patterns, enabling the estimation of the communication times of a message-passing application. Such estimates facilitate activities such as application tuning, selection of the best available implementation technique, and performance comparisons among different multicomputers. 1. Introduction A distributed-memory multicomputer consists of multiple processor nodes interconnected by a message-passing network. Each processor node is an autonomous computer consistingof a central processing unit (CPU), memory, communication adapter, and---for at least some nodes---mass storage and I/O devices. Figure 1 shows a...
