Accelerating Dynamical Density Response Code On Summit And Its Application For Computing The Density Response Function Of Vanadium Sesquioxide, Wileam Y. Phan
Accelerating Dynamical Density Response Code On Summit And Its Application For Computing The Density Response Function Of Vanadium Sesquioxide, Wileam Y. Phan
Masters Theses
This thesis details the process of porting the Eguiluz group dynamical density response computational platform to the hybrid CPU+GPU environment at the Summit supercomputer at Oak Ridge National Laboratory (ORNL) Leadership Computing Center. The baseline CPU-only version is a Gordon Bell-winning platform within the formally-exact time-dependent density functional theory (TD-DFT) framework using the linearly augmented plane wave (LAPW) basis set. The code is accelerated using a combination of the OpenACC programming model and GPU libraries -- namely, the Matrix Algebra for GPU and Multicore Architectures (MAGMA) library -- as well as exploiting the sparsity pattern of the matrices involved in …
Machine Learning Applications For Waveform Analysis, Micah R. Cruz
Machine Learning Applications For Waveform Analysis, Micah R. Cruz
Masters Theses
Since the later 20th century, the search for physics beyond the Standard Model (BSM) has been paramount to many nuclear and particle physicists. Neutron and nuclear beta decay experiments provide one avenue to search for evidence of BSM physics by contributing to the unitarity check of the Cabibbo-Kobayashi-Maskawa matrix. Many of these experiments detect neutron decay products as digitized waveforms. As computing power increases and novel algorithms are developed, it is compelling to investigate machine learning methods as an analytic tool for such waveform data. These methods can allow for very fast data exploration techniques, and if pseudodata is available …

Calculation And Modeling Of The Neutron’S Magnetic Moment, Abhyuday Sharda
Masters Theses
This thesis presents the current state of neutron magnetic moment calcu- lations. It details the development of calculations through history. It also delves into an experiment measuring the neutron magnetic moment. It ex- plores other methods by which calculations can be improved to get a better/ more accurate number. The conclusion is that there are still a lot of areas unexplored in context of the calculation of neutron magnetic moment and areas relevant to be worked upon are detailed.
