This is the "completely fair scheduler", which is used to distribute tasks over a group of nodes in a fair way (http://en.wikipedia.org/wiki/Completely_Fair_Scheduler).

Thanks William

If you can also know an algorithm work in multiple resources (ex.CPU,Memory,disk storage).

depends on the nature of you problem: Placement or Scheduling?

For scheduling, you already have good infos upward

if placement only: than I advice this work

Hello Mohammad,

It would be better, If the question could be narrowed.

Is your question based on resource allocation in Cloud  Perspective or from the Hypervisor Perspective ?

If it is based on Cloud, from a group of clusters resource is alloted is based on algorithm such as Round Robin, Greedy , Weight based priority scheduling etc.

If it is based on Hypervisor, One of the common algorithm is Credit Scheduling ( Used by Xen Hypervisor)

Thanks Sri,

Its been very helpfull

It is based in cloud perspective.

Here I need a new algorithm to share resource (ex. CPU,RAM and disk storage)
