Performance Regression with TAU

Performance Regression analysis is the study of how an application's performance varies with time. In many cases an application that is actively being developed might benefit from running a test each night to closely monitor changes in the application parallel performance.

This page provides some information about how TAU can provide performance regressions. The basic strategy is to construct a set of scripts that can build and run your application with TAU on a particular machine and also use TAU to gather the resulting performance data for easy analysis.
