SUMMARY:Enabling Neutrino and Antineutrino Appearance Observation Measurem
 ents with HPC Facilities
DESCRIPTION:Poster\nTech Program Reg Pass, Exhibits Reg Pass\n\nEnabling N
 eutrino and Antineutrino Appearance Observation Measurements with HPC Faci
 lities\n\nBuchanan, Calvez, Ding, Doyle, Himmel...\n\nWhen fitting to data
  with low statistics and near physical boundaries, extra measures need to 
 be taken to ensure proper statistical coverage. The method NOvA uses is ca
 lled the Feldman-Cousins procedure, which entails fitting thousands of ind
 ependent pseudoexperiments to generate acceptance intervals that are then 
 used to correct our fits. The scale required by the Feldman-Cousins proced
 ure makes it extremely computationally intensive. In past analyses, it has
  taken up to several weeks to complete, bottlenecking our final results. H
 ere, I present recent work by members of the NOvA experiment and the SciDA
 C4 collaboration to enable the use of the supercomputing facilities at NER
 SC to process our Feldman-Cousins corrections over 50x faster, allowing us
  to perform more studies, increase the precision of our fits, and produce 
 results quickly.
