Hi, I'm trying to understand how
Condor job scheduling works. I have a condor pool with 18 "Unclaimed"
slots. I submit 30 "sleep 90" jobs. 2 of them start quite promptly,
but the next 16 take 20 seconds before they are matched, then all start
at once: -- Submitter: abitibi.sbgrid.org : <10.0.10.39:52783> : abitibi.sbgrid.org ID OWNER SUBMITTED RUN_TIME ST PRI SIZE CMD 93.0 ijstokes 3/21 12:42 0+00:00:56 R 0 0.0 sleep 90 94.0 ijstokes 3/21 12:42 0+00:00:56 R 0 0.0 sleep 90 95.0 ijstokes 3/21 12:42 0+00:00:35 R 0 0.0 sleep 90 96.0 ijstokes 3/21 12:42 0+00:00:35 R 0 0.0 sleep 90 97.0 ijstokes 3/21 12:42 0+00:00:35 R 0 0.0 sleep 90 98.0 ijstokes 3/21 12:42 0+00:00:35 R 0 0.0 sleep 90 99.0 ijstokes 3/21 12:42 0+00:00:35 R 0 0.0 sleep 90 100.0 ijstokes 3/21 12:42 0+00:00:35 R 0 0.0 sleep 90 101.0 ijstokes 3/21 12:42 0+00:00:35 R 0 0.0 sleep 90 102.0 ijstokes 3/21 12:42 0+00:00:35 R 0 0.0 sleep 90 103.0 ijstokes 3/21 12:42 0+00:00:35 R 0 0.0 sleep 90 104.0 ijstokes 3/21 12:42 0+00:00:35 R 0 0.0 sleep 90 105.0 ijstokes 3/21 12:42 0+00:00:35 R 0 0.0 sleep 90 106.0 ijstokes 3/21 12:42 0+00:00:35 R 0 0.0 sleep 90 107.0 ijstokes 3/21 12:42 0+00:00:35 R 0 0.0 sleep 90 108.0 ijstokes 3/21 12:42 0+00:00:35 R 0 0.0 sleep 90 109.0 ijstokes 3/21 12:42 0+00:00:35 R 0 0.0 sleep 90 110.0 ijstokes 3/21 12:42 0+00:00:35 R 0 0.0 sleep 90 Why does this happen?
