If you do a lot of computational work, you're probably familiar with PBS, the Portable Batch System. PBS is a specification for software that allows you to submit jobs to a computer cluster and have them executed. While it's usually used on large, highly parallel cluster computers (with hundreds or thousands of processors), sometimes you might want a copy on a home computer for testing or just to queue up your own personal tasks.
Some time ago I installed TORQUE, an open-source PBS implementation, on my main desktop which runs Gentoo. Here are some tips on the basic procedure I followed.
server USE flag and emerge the package:
echo "sys-cluster/torque server" >> /etc/portage/package.use emerge sys-cluster/torque emerge --config sys-cluster/torque
Check the contents of
/var/spool/torque/server_name to make sure it matches your hostname (output of
/var/spool/torque/server_priv/nodes to make sure that your computer is listed.
np is the number of processors on your system.
Then start it up!
/etc/init.d/pbs_server start /etc/init.d/pbs_mom start /etc/init.d/pbs_sched start
At this point you're good to go. You can test the system by running
echo sleep 30 | qsub, then
qstat should show you that the job is running.
