NOvA success for first results
The NOvA experiment, the largest running experiment
at Fermilab, studies the oscillation parameters that define
neutrino transformation. During the preparation for DPF, dCache was delivering
files at a rate of approximately one terabyte per hour for analysis jobs.
The utilization of FTS, SAM, and dCache allowed for complete integration
into essentially all workflows without customization by analyzers.
While data-heavy processing was focused on workers
nodes near (but not exclusively at) Fermilab, processing, such as Monte
Carlo generation, was transitioned to offsite resources. All off-site opportunistic processing
combined resulted in over 5 million CPU hours and
increased the average number of cores utilized by NOvA from 2,200 cores
on site to 3,250 cores total. More information

GENIE using OSG to improve neutrino interaction modeling
One of the goals of the Fermilab GENIE group has been to move its
validation processing to the Open Science Grid.

Preparing a GENIE
physics release involves intensive computation that is not practical in a
desktop environment. The work is largely "embarassingly parallel," making it easy to spread
out over the Grid and finish in a matter of hours what might otherwise
take weeks. More information

dCache: scaling out to new heights
The dCache data storage system was first adopted by the CDF Tevatron experiment
and then became a backbone of regional CMS Tier-1 data center storage. dCache plays a very important role in helping to deliver major scientific results such as traces of the Higgs boson particle in digitized form.

The world map above shows distribution of dCache clients that have transferred at least one terabyte of data in the last three months. More information

OPOS: the importance of collaboration and cooperation
The
OPOS group facilitates the transfer of tools and know-how among
experiments by helping with the adoption of common tools, such as FIFE's Jobsub, SAMweb, IFDH, etc. As Tingjun Yang said, “I think the
OPOS group is doing a fantastic job, and their contribution is very
much appreciated by the DUNE collaboration.”
