Although I'm not sure how that "mounting" of cpus would avoid people hogging resources. I use a HPC system where users submit jobs and there's a whole complicated queuing system going on to make sure that greedy users don't monopolize the system.
- spease 7y agoYou could make the same argument about mounting disks. You revoke the permissions of the people who abuse those resources, and you don’t expose them to the outside world at large completely unprotected.
- gnufx 7y ago"Queuing" is distinct from the resource management component. If you don't have something like cpusets, processes on shared nodes can indeed hog CPU. There are worse issues with shared resources, like flattening the parallel filesystem, which is one of the things which is at least difficult to manage.
