Nick,
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.
regards,
chandra
