This article describes the profiling of Message Passing Interface (MPI) applications with the Sun Studio Performance Tools. It starts with an overview of MPI performance data, explains how to profile MPI applications, shows examples from the analysis of performance data, and finishes with a discussion of supported MPI implementations.
The Sun Studio Performance Tools require a supported version of Solaris or Linux and a supported version of Java. You can verify that all the appropriate components and patches are installed by running the collect command with no arguments. A description of the general use of the tools can be found in an earlier article.
