Synopsis

gfperf-parallel-autoreplica [-t, --testdir test directory] [-m, --gfarm2fs gfarm2fs mount point] [-l, --filesize file size] [-f, --number number of files] [-r, --replica number of replica] [-s, --stop wait time] [-n, --name group name] [-w, --wait start time]

DESCRIPTION

This command creates specified number of files of specified size in test directory. The created files will be automatically replicated by gfmd. This command measures creation time of the files.

This command is expected to be called by gfperf.rb in parallel.
