Description
vtf2profile is created when TAU is configured with the -vtf=<vtf_dir> option. This tool converts a VTF trace file (*.vpt) to a tau profile set (profile.A.B.C where A, B and C are the node, context and thread numbers respectively).
The vtf file to be read is specified in the command line by the -f flag followed by the file's location. The VTF tracefile specified may be in gzipped form, eg app.vpt.gz. -p is similarly used to specify the relative path to the directory where the profile files should be stored. If no output directory is specified the current directory will be used. A contiguous interval within the vtf file may be selected for conversion by using the -i flag followed by two integers, representing the timestamp of the start and end of the desired interval respectively. The entire vtf file is converted if no interval is given.
Options
-f tracefile
-Specify the Vampir tracefile to be converted.
-p profile
-Specify the location where the profile file(s) should be written.
-i interval_start interval_end
-Limit the profile produced to the specified interval within the vampir trace file.
-c -Opens a command line interface for the program.
-h -Displays a help message.
Examples
To convert a vampir tracefile, trace.vpt, to an equivalent TAU profile, use the following:
vtf2profile -f trace.vpt
To produce a TAU profile in the ./profiles directory representing only the events from the start of the tracefile to timestamp 6000, use:
vtf2profile -f trace.vpt -p ./profiles -i 0 6000
