New sites for MicroBooNE

The MicroBooNE collaboration operates a 170 ton Liquid Argon Time Projection Chamber (LAr TPC) located on the Booster neutrino beam line at Fermilab. The experiment first started collecting neutrino data in October 2015. MicroBooNE measures low-energy neutrino cross sections and investigates the low-energy excess observed by the MiniBooNE experiment. The detector also serves as a… More »

Carefully tailoring your resource requests will increase your job throughput With partitionable slots now the norm on GPGrid, it’s important to have a good understanding of resource requirements. The memory, disk, and maximum runtime available in free job slots changes as users submit jobs. As a result, there may be free slots that have less… More »

Wondering why your jobs have been put on hold? Want to better set your resource requests to make more efficient use of the grid (and to get your jobs starting faster)? This information, and more, will be available in the FIFE monitoring application, Fifemon, soon, and is already available for testing in pre-production (https://fifemon.fnal.gov/monitor-pp/). Starting… More »

FIFE has a Wiki page to help match resource requirements and availability at remote sites Previous editions of FIFE notes have shown glimpses of the tremendous computing resources available on the Open Science Grid. These resources come from a large number of remote sites, each of which has its own limitations and policies regarding opportunistic… More »

MINERvA has been using offline production from OPOS for over a year. The following picture shows almost 200,000 jobs from MINERvA between June and December of 2015. (Note: DUNE’s part of the graph only covers December since they started until OPOS on November 30, 2015.) MINERvA started by using just monitoring services from OPOS, but… More »

The Dark Energy Survey (DES) is in its third year of gathering multi-colored digital images of large swaths of deep space with the 4m diameter mirror of the Blanco telescope on a mountaintop in Chile. The team of physicists, astrophysicists, engineers, computer professionals, technicians and managers who operate the survey are participants in a around-the-clock… More »
