I'm actually curious about how you implemented that. Do you have NUMA
hardware? Do you use a resources manager, and is the cpusets creation
process integrated with it? How do you manage concurrent jobs running
on the same machine: do you pin them on specific CPUs and keep track of
what CPU is busy and which is not, or do you have a way to just limit
the number of CPUs they're using?
As you can guess, I'd be interested in some technical details. :)
