[SCore-users] Gang scheduling details

[Shreenivasa Venkataramaiah]

Hello,

I wanted to know the exact details about the implementation of gang 
scheduling in Score. I am looking for a gang scheduing system which 
works in this fashion:
    - imagine a parallel application to be scheduled on 'n' nodes as 'n' 
processes
    - the scheduling must be such that when this application is run such 
that it has to share the nodes with other jobs, then all the processes 
of this application must be scheduled on all the nodes at the same time. 
Similarly all the processes must be preempted from all the nodes at the 
same time (i.e. if there are still in the running state).
    - I know there are a lot of impelementation issues to be dealt with 
here, but I wanted to know whether something similar is done in SCore 
and if yes, what are the details of the implementation.

thanks,
shreeni.
