Overview
gfgrep is a sample program of parallel applications executed by gfrun(1) as well as an example to create a Gfarm file in the local file view.
gfgrep searches a pattern from input-gfarm-URL, and outputs to output-gfarm-URL.
Every parallel application executed by gfrun(1) should interpret the -I and -N options that show the rank and the size of the parallel program, respectively, and call gfs_pio_set_local().
