Re: [Condor-users] Heterogeneous Meta scheduling

[Miron Livny <miron@xxxxxxxxxxx>]

All,

Condor-G can be used as a scheduler by leveraging its matchmaking 
capabilities. Jobs can be kept in the Condor-G queue while waiting for the 
"right match". You can use Condor tools like HawkEye to collect information 
from the potential sites and send them to the matchmaker. Several 
sites/projects use Condor-G in this capacity. Recently, with the help of 
our European collaborators, we added to Condor "direct" interfaces to PBS 
and LSF. With our recent work on supporting the delegation of Condor jobs 
from one SchedD to another SchedD (Condor-C), one can construct 
heterogeneous schedulers with several layers of matchmaking.
