All, 

just sending along a scale test - 30k jobs submitted.   (We probably need to add the rcc.uchicago.edu pool to cycle server.)

Current snapshot,

[rwg@login ~]$ condor_q | grep R | wc

   2462   29540  201882

[rwg@login ~]$ 

which seems to be the current “reach” of Atlas Connect, given our priority settings presently.   I can’t wait until we get stampede connected.

The only snag I hit was the number of log files written to my home directory (I was asking for 90k files in a single directory).  Once I reduced it to 30k, all proceeded smoothly.

Some plots with the distribution:

This show’s we’re getting about 280 jobs going on AGLT2 at the moment, not bad.

Both UC3 and Fresno have topped out:

So - I’m obviously writing too many files to my home directory.   I changed my submit file

to have the jobs share err and log files.

Resubmitting 30k jobs.

Hopefully not making too much a mess.

Ah, I have broken it:

[rwg@login connect-quickstart]$ condor_q 

-- Failed to fetch ads from: <192.170.227.199:55997> : login.atlas.ci-connect.net

Lincoln,

I might have broken AC.  I was testing my luck - submitted 30k jobs, attempted to see what I might get.

At some point, during the submission, I got a bunch of error messages - could not write to the home directory err, out, and log files.

I removed all the jobs.

Re-submitted 20k jobs, this time without errors.
