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.
