NAME¶
vtf2profile - Generate a TAU profile set from a vampir trace file
SYNOPSIS¶
vtf2profile
[ -p profile]
[-i interval_start interval_end] [-c]
[-h] {-f tracefile}
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
