NAME
gfsched - create a host file using file-affinity scheduling
SYNOPSIS
gfsched [ -U ] [ -I fragment-index ] [ -p gfarm-program-URL ] gfarm-URL
[ output-hostfile ]
gfsched [ -U ] -N number [ -p gfarm-program-URL ] [ host ... ]
DESCRIPTION
gfsched creates a host file using the file-affinity scheduling of
gfarm-URL. In other words, gfsched chooses and displays hostnames,
matching the number with the fragments of the gfarm-URL, giving
priority, as far as possible to the host which has the fragment. When
output-hostfile is omitted, gfsched displays to the standard output.
If -N is specified instead of gfarm-URL, gfsched chooses and displays a
specified number of hosts from the hosts in the arguments. If no hosts
are specified in the argument, gfsched chooses hosts from all
registered hosts.
OPTIONS
-I fragment-index
Specifies the fragment index to be scheduled.
-U Suppresses authentication check. Without this option, the
scheduler checks whether the user will be successfully
authenticated with the hosts or not. This option omits the
check to make scheduling faster, but that creates a risk that
hosts which fail authentication with the user may be scheduled.
-p program-URL
Creates a host file with a program name which will be used to
process the gfarm-URL. In other words, only hosts which can run
the program-URL will be selected, if this option is specified.
-? Displays a list of command options.
