man setrlimit (or ulimit) This is per user though, and only related to user accounting really as you can only set a limit on the number of CPU seconds used.
I would also really like the ability to throttle any processes back to a certain % of CPU, and extending this to throttling users to certain CPU limits which would be useful also.
Obviously you would set it up so that all available CPU is used, for e.g. if you had 2 CPU bound processes running and you allocated 1 to 40% and the other 60%, when either terminates the other should increase to the available CPU (I can't see any reason why you would forceably limit a process' CPU usage if there was free CPU).
Could the current scheduling logic that uses the nice value of a process, do this, and all I would have to do is have a % specifying wrapper around this?
Any other ideas or will I get hacking..
