Hi Sowmya
>From what I understand CKRM was not a dedicated task scheduler as in
the case of the old O(1) or the CFS but a project working towards the
grouping and identifying of tasks as classes so that they could be
managed/tracked according to a particular resource 'identity' at a
higher systems management level. I don't think the CKRM project is
active any more, but I could be wrong...

In the current kernel this functionality is now I believe provided for
by cgroups. Read the files in Documentation/cgroups/ for more info on
managing process aggregates this way.
