How to get a whole bunch of jobs going while everyone else is sipping eggnog
While everyone enjoys a break from work this time of year, one thing that won’t be taking a break is grid computing. GPGrid will run at full capacity at all times, as will many of the usual offsite computing clusters. We encourage users to continue to submit jobs so that they can run over the holidays.
High-energy physics experiments have an ever-growing need for computing, but all the experiments don't need all the cycles all the time. The need is driven by machine performance, experiment and conference schedules, and even new physics ideas. Computing facilities are purchased with the intention to meet peak workload rather than the average, which impacts the overall computing cost for the facility and the experiment.
The HEP computing model is constantly evolving, and one change that is currently taking place is increased use of High Performance Computing (HPC) resources. Some of these HPC resources include supercomputing sites such as NERSC, as well as the EXtreme Science and Engineering Discovery Environment (XSEDE). XSEDE is actually a collection of several HPC resources, including the Stampede cluster at the Texas Advanced Computing Center.Since the first article appeared in the August 2016 edition of FIFE Notes, the Continuous Integration (CI) project has been implementing new features and on-boarding new experiments and collaborations. DUNE, GlideinWMS, MINERvA and GENIE are ready to try it out. NOvA is using CI extensively for their production releases. Alex Himmel, the NOvA production coordinator, discussed their experience at the October CS liaison meeting. "Continuous integration has been a major benefit to NOvA -- it allows us to catch issues one-by-one as they happen instead of all at once during an official production campaign. In just the last few months it has already saved us from many headaches," Himmel said. Read moreRead more
FIFE provides collaborative scientific-data processing solutions for Frontier Experiments.
FIFE takes the collective experience from current and past experiments to provide options for designing offline computing for experiments. It is not a mandate from Scientific Computing Division about how an experiment should or should not design their offline computing. FIFE is modular so experiments can take what they need, and new tools from outside communities can be incorporated as they develop.
