Re: [Condor-users] Synchronizing concurrent jobs in Condor



Matt has also pointed out concurrency limits may also help.

I am trying to start the jobs in a Condor pool in parallel. As the jobs are concurrent to the database, the simultaneous access decreases the parallel jobs' performance significantly.
