The development of Paraver was co-funded by the HBP Ramp-up Phase. This page is kept for reference but will no longer be updated.

Paraver is a very flexible data browser. The metrics used are not hardwired on the tool but can be programmed. To compute them, the tool offers a large set of time functions, a filter module, and a mechanism to combine two timelines. This approach allows displaying a huge number of metrics with the available data. The analysis display allows computing statistics over any timeline and selected region, what allows correlating the information of up to three different time functions. To capture the expert’s knowledge, any view or set of views can be saved as a Paraver configuration file. Therefore, re-computing the same view with new data is as simple as loading the saved file. The tool has been demonstrated to be very useful for performance analysis studies, giving much more details about the applications behaviour than most performance tools available.

The new version 4.6.0 (3rd February 2016) provides the following new features (externally funded) as compared to version 4.5.6 (February 2015) that was part of the HBP-internal Platform Release in M18:

• Automatic workspaces on trace loading
• Scalability improvements for traces with more than 64K rows
• Support for wxWidgets 3
• Traces with same hierarchy can be combined to analyze
• External tools integration

The new version 4.6.3 (16th November 2016) provides the following new features:

• Added punctual information view to timelines
• Added external tool Run->Spectral from timelines
• Trace load time reduced by 25%
• Histogram new features: show only totals and short/long column labels
• Run app dialog usability improvements
