Or use cron on the headnode to submit jobs to the clusterscheduler if that does not support recurring timed jobs...

at work (more clusters, all Veritas though) we use autosys, which is
a program scheduler to start programs on other machines.
cron jobs are for jobs which are for each node (e.g. sending a health status
to a central server once a day), thus bound to a physical machine.
autosys is for everything which can move (cluster service groups, e.g.
a DB cleanup job on the node which runs the DB). Since each
service group has its own IP address and DNS entry, autosys simply connect
to that IP address and executes a script (and does more like checking the
status, handling timeouts, sending out alarms if anything went wrong etc.).
Since autosys is commercial software and required quite some infrastructure,
a simpler approach is to set up one machine (maybe cluster it ;-)
which starts jobs on other machines according to a list it maintains.
