Brent Lessley Presents Two Papers at LDAV 2017
CDUX Ph.D. student Brent Lessley presented two recent research results at the IEEE Large Data Analysis and Visualization (LDAV) Symposium today in Phoenix, AZ. His first paper, titled Maximal Clique Enumeration with Data-Parallel Primitives, demonstrated a new algorithm for maximal clique enumeration with an emphasis on portable performance across architectures. This paper also provides some initial encouraging evidence that data-parallel primitives are a viable technique for graph algorithms, whereas most recent research has focused on scientific visualization algorithms. Co-authors on the work include Talita Perciano and Wes Bethel of Lawrence Berkeley, as well as Manish Mathai and Hank Childs. Brent's second paper, titled Techniques for Data-Parallel Searching for Duplicate Elements, built on Brent's EGPGV paper in 2016 which looked at the external facelist calculation problem. As that work was extended to more architectures and more hashing techniques, limits to performance portability were uncovered. His LDAV paper explained these limits and demonstrated best practices. Co-authors on this work included Ken Moreland of Sandia Labs, CDUX alum Matt Larsen (now of LLNL), and Hank Childs.

Best Paper at LDAV
LDAV in Paris. The work, titled Improved Post Hoc Flow Analysis Via Lagrangian Representations, came out of the research from Hank's Early Career Award. The work compares the traditional paradigm for exploring unsteady state flow --- saving time slices and interpolating velocity fields between these time slices --- with a new one. The new paradigm employs Lagrangian tracers in situ during simulation execution and then interpolates positions between these tracers. The paper's experiments showed that the Lagrangian approach is faster, more accurate, and takes less storage than the traditional approach.Hank Childs was part of the team that received Best Paper at
