CNF HPC Workshop
Contents
Overview
The Center for Nuclear Femtography (CNF) High Performance Computing (HPC) Mini-Workshop will be held at the National Institute of Aerospace (NIA): 100 Exploration Way Hampton, VA 23666 on Thursday, October 10th, 2019 from 9am-2:15pm. The Workshop is expected to be highly interactive.
Next generation HPC for processing sensor data for Imaging in Nuclear Femtography is entering one of its very early stages. The complexity from seven-dimensional data and many scales and levels of interactions between the colliding particles and what is observed create many challenges. To address these challenges the “Next-generation imaging filters and mesh-based data representation for phase-space calculations in nuclear femtography (CNF19-04)” project proposed to put together an interdisciplinary team to:
- learn lessons from medical image computing community (see Part I of HPC/Imaging mini-workshop ) and
- leverage advanced software systems from Cloud-, Edge- and Exascale-computing, with the long term aim to enable next-generation process simulations, data analyses, and physics model comparisons
Part II of the CNF series of mini-workshops is bringing together HPC leaders on software systems from ANL and VATech and Computational Fluid Dynamics, Nondestructive Evaluation, and Computational Materials from NASA/LaRC to build State- and Nation-wide bridges for leveraging Exascale- Cloud- and Edge- computing for CNF activities.
CRTC group in the Computer Science field at ODU is collaborating with two of the most advanced groups world-wide in high-performance computing: (i) Argonne National Labs, namely Mathematical and Computer Science (MCS) Division, which "provides the numerical tools and technology for solving some of our nation’s most critical scientific problems", (ii) NASA's LaRC which has a long history in high performance computing with its former Institute for Computer Applications in Science and Engineering (ICASE) and its evolution to the current National Institute for Aerospace (NIA), and (iii) many Computer Science Departments across Virginia’s Commonwealth like VATech, W&M and VCU.
The long-term goal for such activities is the development of an HPC infrastructure for efficient simulation and analysis of nuclear femtography experiments, allowing users to implement physics models, generate phase space distributions, constrain model parameters with forthcoming experimental data (fits), and share/communicate results. This mini-workshop is the first step towards achieving this goal by exploring the potential of further interdisciplinary collaborations involving in- and out-of-state experts and new computational methods.

David Richards
Dr. David Richards is Theoretical and Computational Physics at DOE's Jefferson Lab. Richards came to Jefferson Lab as a staff scientist and joint faculty member at Old Dominion University in 1999. He became a full-time staff scientist in 2002 and served as acting Theory Center leader from September 2009 through October 2010. He was appointed deputy director of the Theory Center in mid-October 2010. Richards' current research focus is aimed at garnering a better understanding of so-called "excited states." These are subatomic particles that were once the familiar protons and neutrons, but now have additional energy. The experimental determination of their masses and properties is an important effort at Jefferson Lab. Richards and his colleagues use supercomputers at Oak Ridge National Lab, and the high-performance GPU-enabled (graphics processing unit) clusters at Jefferson Lab, to compute the masses and properties of these excited states from first principles, using lattice QCD. Comparing these calculations with experimental data provides crucial insights into the nature of matter and how the masses of so-called hadronic matter, such as protons and neutrons, arise from QCD. A particularly exciting recent calculation is that of the masses of so-called "exotic mesons," mesons that cannot be constructed from straightforward excitations of a quark and an antiquark, the fundamental building blocks of QCD. The search for such mesons is the aim of the GlueX experiment with CEBAF at 12 GeV. Richards and his colleagues predict that there will be exotic mesons at a mass that will be accessible to GlueX, underpinning the scientific imperative for the experiment. Throughout his career, Richards has received numerous awards, including scholarships at Cambridge and an advanced Fellowship at Edinburgh. He serves on committees such as the Lattice QCD Executive Committee and was the co-organizer of Lattice 2008, the 26th International Symposium on Lattice Field Theory held in Williamsburg, and a panel convener for Forefront Questions in Nuclear Science and the Role of High Performance Computing, held in 2009 in Washington, D.C.
Gagik Gavalian
Dr. Gagik Gavalian is a Staff Scientist at Jefferson Lab and Assistant Professor at Old Dominion University. He attended Yerevan State University and graduated in 1996 with a major in Physics. He obtained his Ph.D. in Nuclear Physics from the University of New Hampshire in May 2004. Gagik then served as a Post Doctoral Research Associate at Old Dominion University until 2008. He then assumed the role of Assistant Professor at Old Dominion until 2014, where he taught introductory physics and conducted research at Jefferson Lab. Gagik played an instrumental role in the Hall B data mining efforts leading to multiple publications on studies of nuclear effects in electron-nucleus scattering. Gagik joined Jefferson Lab as a staff scientist in 2014 and has been working on preparing the CLAS12 data analysis packages towards expedient analysis. He also mentors Doctoral candidates and college students. For past four years Gagik worked on implementing CLAS12 detector reconstruction packages in cloud distributed CLARA framework. CLAS12 detector was successfully commissioned in February 2017 with reconstruction software successfully tested for full data production. For the past (2017-2018) year Gagik was leading effort in development of physics analysis software for CLAS12 experimental data.
