Here are some requirements we(Resource Groups aka CKRM) are working towards (Note that this is not limited to CPU alone):
In a enterprise environment: - Ability to group applications into their importance levels and assign appropriate amount of resources to them. - In case of server consolidation, ability to allocate and control resources to a specific group of applications. Ability to account/charge according to their usages. - manage multiple departments in a single OS instance with ability to allocate and control resources department wise (similar to above requirement :) - ability to guarantee "time to complete" for a specific user request (by controlling resource usage starting from the web server to the database server). - In case of ISPs and ASPs, ability to guarantee/limit usages to independent clients (in a single OS instance). - Ability to control runaway processes from bringing down the system response (DoS attacks, fork bombs etc.,)
In a university environment (can be treated as a subset of enterprise requirements above): - Ability to limit resource consumption at individual user level. - Ability to control runaway processes. - Ability for a user to manage resources allocated to them (as explained in the desktop environment below).
In a desktop environment: - Ability to control resource usage of a set of applications (ex: infamous updatedb issue). - Ability to run different loads and get the expected result (like checking emails or browsing Internet while compilation is in progress)
Generic: Provide these resource management capabilities with less overhead on overall system performance.
