sge_schedule

NAME

sge_schedule - format of the Grid Engine schedule file

DESCRIPTION

The schedule file is written by the qmaster when MONITOR=1 is set in the params item of sched_conf(5).

Note that the file tends to grow rapidly, and should be truncated/rotated, e.g. with logrotate(1). Also it should probably be placed on local disk, not an NFS-mounted filesystem, for instance, because of the large number of small writes it typically gets - e.g. make a symbolic link into the qmaster spool area (assuming that is local).

See qsched(1) for a tool to process the data and produce information on reservations.
