   Cannot be sure - but try to google in direction of "vserver linux".
   Digging into the lkml archives on vserver can give you some pointers.
   At least some posters were hinting that vserver has capability to 
limit CPU usage of given task.

Hi Vda,

IS THERE AN APPLICATION WHICH RUNS UNDER Linux to do this work?


Thanks

This is a bit off-topic for lkml, but...

AFAIK, no. You'll have to code your own.

You can also run a lot of top programs, each for one user (type 'u' 
while in top).

nb. is their a way to get fair 'equal time / proc percentage per user' 
queueing of the CPU(s).

i.e. not limiting the number of processes/user but limiting the total CPU 
'power' in use by a given user, something like the CBQ network 
schedulers... perhaps with some classes (like root) more priveledged 
etc... or is this something for 2.7?

Cheers,

Yes. Rik, IIRC, has a "fair cpu scheduler". I've seen several version of 
this patch to 2.4. Not sure about 2.6, thou...

You may also want to inspect CKRM (Class-based Kernel Resource 
Management) in http://ckrm.sourceforge.net/
