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 is also on the writing committee for the new joint IceCube U. S. NSF proposal.

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 2 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 ‘18 allocation of 1,250,000 CPU hours (equivalent to 114 cores running 24/7/365) this year on NERSC supercomputer systems. Unfortunately, IceProd does not run easily on NERSC systems, so NERSC could not contribute to standard IceCube Monte Caro production. There have been some recent changes which are leading us see if IceProd can be made to work here. If this is possible, there are also some encouraging indications that we could get a significant increase in CPU allocation.

Our analysis efforts are focused in several areas.

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

New graduate student Yang Lyu will most likely 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.
