The Annai/PMA Performance Monitor and Analyzer

The Annai integrated tool environment helps exploit the inherent power of distributed-memory parallel computers with standardized languages and convenient programming support. Portable application development is supported in High Performance Fortran and/or with explicit messagepassing, using MPI as the machine interface. Integration within a unified tool environment allows the performance monitor and analyzer (PMA) component to interact with source code browsers and the loaded executable on the same terms as when using the parallel debugger. Data distribution and other program information furnished by the parallelization support and compilation systems is also exploited for additional insight. Powerful, directed analysis and interactive graphical summaries address scalability, while detailed charts of the time-varying behavior of individual processes and communication events can also be browsed when desired, always retaining essential reference to the original program source code.
