tau2otf2 — convert TAU tracefiles to OTF2 tracefiles for Vampir/VNG
This program is generated when TAU is configured with the -otf=<otf_dir> option. The tau2otf2 trace converter takes a TAU formatted tracefile (*.trc) and a TAU event description file (*.edf) and produces an output trace file in the Open Trace Format (OTF2). The user may specify the number of output streams for OTF2. The input files and output file must be specified in that order. TAU traces should be merged using tau_merge prior to conversion.
-n streams Specifies the number of output streams (default is 1).
-nomessage Suppresses printing of message information in the trace.
-v Verbose mode sends trace event descriptions to the standard output as they are converted.
The program must be run with the tau trace, tau event and otf2 output files specified in the command line in that order. Any additional arguments follow. The following will produced an OTF2 file, a pp.otf2 and other related event and definition files, from the TAU trace and event files merged.trc and tau.edf trace file:
