Turning on Performance in LAMMPS Molecular Dynamics

Presenter(s): Kent Milfeld (TACC)

Principal Investigator(s): Peter Koenig (Procter & Gamble)

Presentation Slides

LAMMPS is a large-package atomistic and molecular dynamics simulator. Through the Industrial Challenge Program TACC supported Peter Koenig (PI) in using LAMMPS on the Stampede system. The object of the program was to create atomistic and particle simulations that could be used to determine micellar properties to confirm and replace experiments that develop rheology models for mixing, filling, and product performance predictions. The presentation will focus on the support work: LAMMPS optimizations, which included a few code changes, a description on adding new Classes (styles) for modifying interactions, and other efforts supporting efficient use of the Stampede system

Curation en masse: Exploration of the Quality of Video Collections

Presenter(s): Anne Bowen (TACC)

Principal Investigator(s): Alan Bovik (UT)

Presentation Slides

TACC provided support for Alan Bovik (Laboratory for Image and Video Engineering at UT Austin) to assess the use of automatic quality assessment algorithms at a large scale for museum digital video collections. This project involved developing a visual analysis tool and workflow for massive video quality assessment on TACC systems using the BRISQUE algorithm. The presentation will present an overview of the Quality Assessment workflow, and specifically focus on the challenges we encountered with using BRISQUE (and non-referential quality assessment algorithms in general) on museum collections. These challenges prompted the development of the visual analysis tool to assist with interpretation of the results.
