NAME

       tau2vtf - convert TAU tracefiles to vampir tracefiles

SYNOPSIS

       tau2vtf [-nomessage] [-v] [[-a] [-fa]] {tau_tracefile} {tau_eventfile} {vtf_tracefile}

DESCRIPTION

       This program is generated when TAU is configured with the -vtf=<vtf_dir> option.

       The tau2vtf trace converter takes a single tau_tracefile (*.trc) and tau_eventfile (*.edf)
       and produces a corresponding vtf_tracefile (*.vtf). The input files and output file must
       be specified in that order. Multi-file TAU traces must be merged before conversion.

       The default output file format is VTF3 binary. If the output filename is given as the
       .vpt.gz type, rather than .vpt, the output file will be gzipped. There are two additional
       output format options. The command line argument '-a' produces the vtf file output in
       ASCII VTF3 format. The command line argument '-fa' produces the vtf file output in the
       FAST ASCII VTF3 format. Note that these arguments are mutually exclusive.

OPTIONS

       -nomessage Suppresses printing of message information in the trace.

       -v Verbose mode sends trace event descriptions to the standard output as they are
       converted.

       -a Print the vtf file output in the human-readable VTF3 ASCII format

       -fa Print the vtf file in the simplified human-readable FAST ASCII VTF3 format

EXAMPLES

       The program must be run with the tau trace, tau event and vtf output files specified in
       the command line in that order. Any additional arguments follow. The following will
       produce a VTF, app.vpt, from the TAU trace and event files merged.trc and tau.edf trace
       file:

       tau2vtf merged.trc tau.edf app.vpt

       The following will convert merged.trc and tau.edf to a gzipped FAST ASCII vampir tracefile
       app.vpt.gz, with message events omitted:

       tau2vtf merged.trc tau.edf app.vpt.gz -nomessage -fa
