Mu2e Offsite Simulation Campaign:
Utilizing the Open Science Grid to increase sensitivity to new physics

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.

Introducing OPOS 

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

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% efficiency.

Service updates monitoring: Why are my jobs not running?

Fifemon, the 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.
