Opportunities in HPC and Graphics: Perspectives of a Current Student

SESSION: Graphics and Visualization Technologies

EVENT TYPE: HPC Interconnections, Broader Engagement

TIME: 4:30PM - 5:00PM


Presenter(s):Michael Driscoll


3D computer graphics abounds with problems for high-performance computing research. Many graphics applications strive to provide high-fidelity experiences to artists and audiences, and HPC techniques are one means of achieving that goal. In this talk, Ill focus on two graphics kernels that can be implemented efficiently by reducing them to common patterns found in scientific computing. The first kernel computes the location of surfaces for complex shapes commonly found in animated feature films. Ill show how it can be implemented with sparse matrix-vector multiplication to yield twice the performance of existing approaches. The second kernel computes the location of a characters hair as he or she moves through time, i.e. hair simulation. Ill describe a new, communication-avoiding algorithm for particle systems that promises good performance for hair simulations on distributed-memory machines. Ill conclude with a few more problems in graphics that can benefit greatly from high-performance implementations.
