| - | * [[/bin|/bin]] | + | Campusrocks uses sungrid for scheduling jobs. The techstaff request that jobs only be run |
| - | * [[/bin/x86_64|/bin/x86_64]] | + | on the compute nodes, not the head node, as jobs run there slow down the entire cluster. |
| - | * [[/bin/scripts|/bin/scripts]] | + | They threaten to kill jobs found running on the head node. |
| - | * [[/data|/data]] | + | |
| - | * [[/programs|/programs]] | + | There is [[http://campusrocks.soe.ucsc.edu/roll-documentation/sge/5.2/|Online documentation]] of how to use sungrid to submit jobs on the cluster. The main commands are |
| - | * [[/libs|/libs]] | + | * qsub: Submits a job (create a shell script, then run "qsub -cwd shellscript") |
| - | * [[/experiments|/experiments]] | + | * qdel: Delete a job |
| + | * qlogin: Interactive login | ||
| + | * qstat: See the status of jobs in the queue | ||

| + | |||
| + | Useful submit-script settings for SGE: | ||
| + | |||
| + | #$ -N some_name_here\\ | ||
| + | apparently, you must have a single word after -N\\ | ||
| + | This gives a nicer name to your script when you run qstat.\\ | ||
| + | |||
| + | #$ -V\\ | ||
| + | Your jobs use **your** environment variables. | ||
