normally I would refuse to answer as I'm biased, but as there are no
replies at all: I would suggest to look into SGE: http://
gridengine.sunsource.net/ The requested automatic suspend feature is
supported by implementing a subordinated queue for long running jobs
in the long-queue. To start the short running jobs every day at a
fixed time, you could use a calender for the short-queue, which will
be enabled for a few hours every day and then drain again while the
