Aftermath: Trace-based Performance Analysis for OpenMP and OpenStream

Aftermath is a graphical tool for the trace-based performance analysis of OpenMP and OpenStream programs. The tool allows programmers to relate performance data from a parallel execution to the programming model, e.g. to loops and tasks in OpenMP. Aftermath supports the interactive exploration of trace files, the generation of detailed statistics for arbitrary subsets of a trace on-the-fly and the inspection of individual events in detail. Aftermath is free software, released under the GNU GPL v2 and its tracing library is licensed under the GNU LGPL v2.1.
