Open Trace Format Version 2 (OTF2)

OTF2 developer community

The Open Trace Format Version 2 (OTF2) is a highly scalable, memory efficient event trace data format plus support library. It is the standard trace format for Scalasca, Vampir, and Tau and is open for other tools.

OTF2 is available under the 3-clause BSD Open Source license.

OTF2 is the common successor format for the Open Trace Format (OTF) and the Epilog trace format. It preserves the essential features as well as most record types of both and introduces new features such as support for multiple read/write substrates, in-place time stamp manipulation, and on-the-fly token translation. In particular, it will avoid copying during unification of parallel event streams.

Version 2.3 comes with the following changes:

  • Update Jinja template engine to 2.11.2 and support Python 3 for the generator. Minimum version is now 2.7.

  • Add paradigms for HIP accelerators and Kokkos.
