Hello,
I would like to know if the linux kernel has a
mechanism to control computing resources at a uid
level, which I will call "resource provisioning". For
example, I would like to define on a multi cpu machine
that a list of uid's can not consume more than 1 cpu
and no more than 1G RAM, irregardless or how many jobs
they launch on or to the system.
So I guess, is this the correct term and is there a
posibilitity to do this now?
I would like to avoid the virtual servers method as I
do not want to carve the machines in question into
more machines.
Thanks for the help!
Phy

You can already do this in some pretty crude fashion via rlimits and
sched_setaffinity (although the later doesn't have direct pam support
that I know of, so you'd have to manage that on your own).

Otherwise, you must look at out of tree patches. Linux-vserver does
this, CKRM will allow you resource control, and PAGG + other module
(perhaps job?) will give you this as well.

Note: the vserver method above doesn't create actual virtual machines,
more like a software construct that you could consider a resource domain.

Thanks for the information Chris. This is a good
starting point.
