Re: [Condor-users] Delay on submit, and other newbie issues

It's not that kind of workload, we'll be running 8-12 parallel jobs at
the most on our 16 current slots, we just want them to always run on the
most available and non-disruptive slot.

I've shorten it to 3 sec, and it still seems like it's 10-15 seconds
until a job starts. I'll clock it more closely and see what I find.

ahh.. nice..  however I see that I can only see jobs I submitted on the
same machine by default...
wait, found it... condor_q -global. Can I make it the default somehow to
do I need to wrap that in an alias?

also, I see jobs submitted from other hosts are not in the same
"cluster"? I thought all my queue entries are submitted to the same
pool!

I can't seem to use condor_rm to manage the queue if I'm not logged on
to the same machine (unless I missed something again). It's very
confusing that job monitoring and management is not symetric like that.
I'm not sure why this is, but more importantly, how do I fix this?

ahh, yes, time to figure out those universe notions :) I'll look into
it.

Thanks for all your help so far!
