$ /usr/share/pvm3/bin/LINUXI386/trcsort -h

usage:  trcsort [ <trace_infile> ] [ -o <trace_outfile> ] [ -O <output_file> ] [
-v ] 

where:
------
<trace_infile>    =    trace file to be sorted (default is stdin)
<trace_outfile>   =    file to store sorted trace (default is stdout)
<output_file>     =    file to store separate copy of any task output
-v                =    display dynamic open file usage

Comment 2 Doug Ledford 2008-06-19 18:16:29 UTC

This program isn't intended to be run by hand, and when run by pvm/xpvm, the
options are controlled so this isn't an issue.
