[Condor-users] Mixed 6.8.6 and 6.9.5 installation

["Robert E. Parrott" <parrott@xxxxxxxxxxxxxxxx>]

Hi folks,

We have a cluster of 240 processors, managed by condor v6.8.6, and  
have some users who would like to schedule 1000 jobs at once. At full  
throttle I can imagine seeing 5000 jobs in under condor_q if we let  
the users run free.

I understand that schedd and other daemons are single threaded, and  
with that many jobs can show significantly reduced performance, but  
that in v6.9.5 this has been refactored, which is a significant  
attraction to the development series.

My question is how one might make use of the updated condor daemons  
on the frontend and submit machine, without having to upgrade all the  
compute nodes. Would this be possible?  What would be needed to do so  
in a graceful manner?

thanks,
rob
