Using Torque in generalFor information on using the PBS/Torque batch system, take a look at our PBS/Torque pages.
Submitting jobs to the Etwin farm (non-GRID)Jobs can be submitted from eprexb or eprexa or most PCs to the "E" twin farm (for example):
qsub4 -j oe -l walltime=24:00:00 myfile.sh
qsub5 -j oe -l walltime=24:00:00 myfile.shdepending on whether you want your job to run under SL4 or SL5. Notice the use of the
-l(lower case L) option to specify limits.
The job output file will be stored in the directory that was the current directory when you submitted the job, as usual. This has to be a writeable directory in /home/. (And not the local /tmp directory, for example). The default walltime is small so do not rely on the default.
This farm can see all files in the /home/ file systems.
