IceCube Institutional Memorandum Of Uderstanding (MOU)

LBNL is involved in many aspects of IceCube service. We built the DOM main boards, and many of our service tasks are related to that, including maintenance of DAQ hardware (contributing to firmware and online software updates). PI Klein was on the writing committee for our current NSF analysis grant.

We are also heavily involved in software work National Energy Research Supercomputer Center (NERSC) at LBNL’s National Energy Research Supercomputer Center (NERSC). NERSC is responsible for storing a copy of all of IceCube’s raw data on their HPSS storage system. Currently, NERSC is storing over 3.5 Petabytes of data for IceCube. This is a lot of data, and we have been heavily involved in developing the data transfer procedures.

We also have a FY ‘20 allocation of 2,250,000 CPU hours (equivalent to 205 cores running 24/7/365) on NERSC supercomputer systems. With IceProd working at these systems, most of this time should be used for IceCube production running.

Our analysis efforts are focused in several areas.

Sally Robertson is working on a multi-year measurement of muon-neutrino absorption in the Earth.

Graduate student Yang Lyu is starting to work on a study of high-energy down-going neutrinos. He plans to develop algorithms to select single muon events (developed for the forward muon search) to reject muon bundle background. In parallel track, we are working with a group of computer scientists (using their own funding) to make a similar selection using machine learning methods. So far, this is just using simulation, but early efforts are promising.
