Most opportunistic cycles for a site was Syracuse University OrangeGrid (SU-OG), which provided over 5.4 million hours.
Most efficient experiment on FermiGrid that used more than 500,000 hours since August 1st was SeaQuest : 82.22% efficiency.
Most efficient big non-production user on FermiGrid since August 1st was Laura Fields from DUNE with 98% efficiency.
Experiment with the most opportunistic hours on OSG was Mu2e with 11,183,034 hours.

Mu2e was able to utilize more than 20 million
CPU hours in only 5 months, averaging more than 4000 concurrent jobs
with peak usage as high as 20,000 simultaneous jobs. This was without
any direct capital expenditures from Mu2e.

Offline Production Operations Service (OPOS) helps
transform the raw data collected by detectors into a format that
scientists can interpret.

The OPOS team contains skilled computing scientists and physicists from
different regions of the world. Their combined expertise
assists Fermilab experiments in running their large-scale production
data. Click here for more information.

Helpful hints -- A SeaQuest tale: the Quest for Open Science Grid
SeaQuest was in a difficult situation this summer: a looming deadline for two fall conferences, a big crunch for data processing in preparation for them, the need for final tweaks to the tracker code with pressure on the few experts that could make it all happen. It became apparent that FermiGrid would not have enough opportunistic cycles to finish this computation. SeaQuest was running out of time and resources to deliver on key physics results. FIFE helped SeaQuest use resources available on the OSG.
With FIFE support, SeaQuest was successful
in running on OSG. Overall, the experiment ran 1,100,000 CPU hours for 185,000
jobs, transferring 7.5 TB of input data and 9.5 TB of output. About 10% of the
computing was executed at 10 OSG sites, running for the last 3 days of the
campaign at the level of 500-1,000 CPU slots continuously, with an overall 90%

Service updates monitoring: Why are my jobs not running?
near-real-time monitoring system for Fifebatch, enables users to see at a
glance the status of their jobs, their experiment’s jobs and the
status of the Fifebatch system to answer
the question of why their job isn't running.
