Re: [HTCondor-users] ERROR: Failed to connect to local queue manager

I found back when we first switched to HTCondor, users would loop through condor_submit calls since that's how they used to do it with Grid Engine qsub. It took some time for them to get the hang of how $(Process) and queue worked. Once they did, they were pleased to submit 1,000 Monte Carlo runs in seconds, instead of 20 minutes. And in 8.4, with the queue in/matching/from feature, it's another bit of learning curve and code changes to simplify things even more and make submissions that much more efficient.

Users running a zillion condor_submits will never regret learning how to properly set up a "queue 1 zillion".
