A toolset, PACE (PerforAnCE analysis environment) for predicting and analysing performance issues in parallel systems is presented here. In this toolset expert knowledge about performance evaluation techniques is not required as a prerequisite for its use. Instead, an intuitive approach is taken by describing the application under study in way that is accessible to the user. A modular approach is taken which permits separate descriptions of sub-tasks, parallelisation strategies, and platform descriptions to take place. PACE has been used to predict performance for number of applications on a number of different parallel platforms. Results to date have indicated that the predictions typically within 5-7% of actual measurements. 1. Introduction A number of performance tools have been developed to assist the system developer, the application programmer, and the tuning expert to select the most efficient use of hardware, and parallelisation strategy [1-5]. However, many of the performanc...
