Bug#391931: linux-image-2.6.18-1-686: CPUSET support for smp images?
Package: linux-image-2.6.18-1-686
Version: 2.6.18-2
Severity: wishlist
Is there a plan to enable the cpuset feature in the kernel?
(This is the CONFIG_CPUSETS tag in the configuration file.)
We are using this feature on each nodes of our clusters (~5000 cpus).
It permits :
- to restrict processes on a subset of cpus,
- to restrict processes on a certain amount of memory (and physical
addresses),
- to keep the list of all children of a process (even if a process
forks and is detached from its father).
So this is very usefull in our cluster context to give a part of a
computer to a user and another one to another user (we can do that with
xen or another VM but it is too slow for a HPC usage).
