Open Trace Format API
Open Trace Format API Documentation


This library supports efficient parallel and distributed access to trace data and offers selective reading access regarding arbitrary time intervals, process selection and record types. Optional auxiliary information can assist this selective access.

The Open Trace Format makes use of a portable ASCII encoding. It distributes single traces to multiple so called streams with one or more files each. Merging of records from multiple files is done transparently by the OTF library. The number of possible streams is not limited by the number of available file handles.

OTF is available under the BSD open source license that allows free usage for academic and commercial applications.
