Matt Larsen Presents Research Results at SC16
CDUX Ph.D. student Matt Larsen presented his recent research results at the SC16 conference in Salt Lake City, UT. His paper, a Best Paper Finalist, was titled Performance Modeling of In Situ Rendering.

Matt Larsen's SC16 Submission Selected as Best Paper Finalist
Matt Larsen's submission to the SC16 conference was selected as a Best Paper Finalist. The title of his paper is "Performance Modeling for In Situ Rendering." His study looked at three rendering techniques (rasterization, ray-tracing, and volume rendering), and multiple architectures (GPU and CPU) and built a performance model over diverse rendering workloads. The results are useful, since visualization algorithms frequently need to fit within in situ constraints, and this model will allow researchers to predict whether they can. Co-authors on the work include James Kress and Hank Childs of CDUX, as well as Cyrus Harrison of LLNL and Jeremy Meredith and David Pugmire of ORNL. Congratulations everyone!!
