Any suggestion is welcome.
More information needed.
Are you talking about sending pending jobs to free cores? Doesn't the
kernel scheduler just do that itself?
What problems have you had with the 'at' tools that you need to address?
I made some progress since my post:
I am not really looking for an alternative to `at',
but rather something similar `Torque':

May be this tools is too powerful for a single computer:
hence my request.
There's a huge difference between managing a cluster and managing
cores/CPUs on one system. The biggest, is that one system runs one
kernel whereas the cluster runs one for each box.
AIUI, the linux kernel will use one core until it gets to 80% used (20%
idle or so) before it powers-up and begins to use a second core. Also,
most apps aren't written to be able to use multiple CPUs.
Single-threaded apps only use one CPU.
What is it about 'Torque' that you find you need on your box?
