Submit Jobs

Users can submit their jobs to judge* with lsbatch like commands. Using these commands, users can run their jobs without login to hosts preserving environment variables and current working directory.


Command	Usage	Description
jsub	jsub [-m hostname] job	Submit job to a given host. If hostname is not given, it is selected with its load average. The result is reported by e-mail. Stdout and stderr of jobs are written in $HOME/jspool/*.{out,err}. They will be removed after 2 weeks.
jrun	jrun [-m hostname] job	The same as jsub, but the result is not reported by e-mail.
jjobs	jjobs [-h|--help] [-l] [[-u username |-u all] | [JOB_ID...]]	Show status of batch jobs of given users or given JOB_ID.
jtree	jtree [-a] [-c] [-l] [-n] [-p] [-u] JOB_ID...	Show process tree of given jobs. Command line options are the same as those of pstree. See pstree man pages.
jkill	jkill JOB_ID...	Terminate given job(s). You can know JOB_ID of your jobs with jjobs command.
jrenice	jrenice priority JOB_ID...	Change priority( nice value ) of given jobs. Only root can make nice value smaller ( = higher priority ).
jpeek	jpeek JOB_ID...	Display the stdout and stderr output of given jobs.
ipcdistclean	ipcdistclean [-a] [-u user] [-h]	This is mainly for Belle users. The basf sometimes dies without cleaning used resources. This command remove all ipc resources of the user. Only root can specify other user or -a option (all users). Do NOT run this command when your job runs.
