| [perfcatcher](http://www.sgi.com/) | Light-weight application profiler for SGI MPI |
| [PerfReports](http://www.allinea.com/") | helps you address the question of quality of utilization. It provides a one page HTML report - collecting, analyzing and reporting the key metrics that impact performance. It can be used without changing either the source code or the application - removing the barriers and opening access to everyon |
| [PerfSuite](http://perfsuite.ncsa.illinois.edu/") | PerfSuite is a collection of tools, utilities, and libraries for software performance analysis where the primary design goals are ease of use, comprehensibility, interoperability, and simplicity. This software can provide a good "entry point" for more detailed performance analysis and can help point the way towards selecting other tools and/or techniques using more specialized software if necessary (for example, tools/libraries from academic research groups or third-party commercial software |
| [Scalasca](http://www.scalasca.org/) | Scalasca is a software tool that supports the performance optimization of parallel programs by measuring and analyzing their runtime behavior. The analysis identifies potential performance bottlenecks – in particular those concerning communication and synchronization – and offers guidance in exploring their causes. |
| [Score-P](http://www.vi-hps.org/projects/score-p//) | Score-P offers the user a maximum of convenience by supporting a number of analysis tools. Currently, it works with Periscope, Scalasca, Vampir, and Tau and is open for other tools. Score-P comes together with the new Open Trace Format Version 2, the Cube4 profiling format and the Opari2 instrumenter (see below). Score-P is available under the New BSD Open Source license. |
| [Vampir](http://www.vampir.eu) | The Vampir software tool provides an easy-to-use framework that enables developers to quickly display and analyze arbitrary program behavior at any level of detail. The tool suite implements optimized event analysis algorithms and customizable displays that enable fast and interactive rendering of very complex performance monitoring data. |
| [VampirServer](http://www.vampir.eu) | The Vampir software tool provides an easy-to-use framework that enables developers to quickly display and analyze arbitrary program behavior at any level of detail. The tool suite implements optimized event analysis algorithms and customizable displays that enable fast and interactive rendering of very complex performance monitoring data. |
