Specifying an output file, option -o

With

  poe /usr/local/packages/actc/hpmtk/pwr4/bin/hpmcount -o outfile parallel_prog.x

HPMCOUNT will write the counter results to a set of files starting with the string specified as argument for the -o option, which is outfile in the above example. Without the option -o the results are written to the standard output. For parallel jobs, if -o is specified, there will be separate file for each processor.

Even with the -o option HPMCOUNT will write some information to stdout. This can be changed with the -n option.
