IMPORTING BY SPLITTING TO SPECIFIED NUMBER OF FRAGMENTS

gfsched -N 8 | gfimport_text -H - -o gfarm:file source_file
IMPORTING BY SPLITTING TO SPECIFIED NUMBER OF FRAGMENTS FOR PARTICULAR PROGRAM
The following is an example using gfimport_text to import a source_file as gfarm:file by splitting to 8 fragments to be processed by gfarm:prog program.
gfsched -N 8 -p gfarm:prog | gfimport_text -H - -o gfarm:file source_file
IMPORTING INTO SAME DISPOSITION WITH AN EXISTING GFARM FILE
