If you renice the job to a prority of 19 it won't get any cpu time
unless the cpu is free. It is also possible to autonice them to a
specified priority after a specified time. You can do this using
dxkerneltuner on the proc system and setting:
autonice 1
autonice-time 600 (for 600 seconds or whatever you want)
autonice-penalty 19

If you are running V5.1A or later (and later isn't available yet),
then the ARMTech active resource management software might help.
To get it to really do what you want, you'd need the enhanced "plus"
level of functionality, I suspect, which is separately licensed from
the base OS by Aurema (www.aurema.com).
Or you can define processor sets (especially useful if you have a
multiprocessor system) and put the "restricted" processes into a
pset that has only one or even no CPUs to service it, and leave
the rest of the CPUs to run the rest of the workload.
By the way, if "nice" isn't doing what you think you need, then it
isn't just about CPU cycles, there are other factors involved in
not prioritizing the "front end" work, but you haven't really said
anything useful about why you think there is a problem or why you
are not getting the results you expected, so it's really hard for
anyone to give you any really useful hints.

I really like this "brainstorming" and wonder, how efficiently admins did their work in times of no conferences like this one.
Thanks to everybody
