HPCToolkit is an open-source suite of multi-platform tools for profile-based performance analysis of applications. The figure provides an overview of the toolkit components and their relationships.
The toolkit components include:
- hpcrun: a tool for profiling executions of unmodified application binaries using statistical sampling of hardware performance counters.
- csprof: a tool for collecting call path profiles of optimized application binaries.
- bloop: a tool for analyzing application binaries to recover program structure; namely, to identify where loops are present and what program source lines they contain.
- hpcprof: a tool for interpeting sample-based execution profiles and relating them back to program source lines.
- hpcview: a tool for correlating program structure information, multiple sample-based performance profiles, and program source code to produce a performance database.
- hpcviewer: a java-based GUI for exploring databases consisting of performance information correlated with program source.
