GPU Accelerated Visualization and Analysis in VMD
Speakers:
John Stone
Abstract:
State-of-the-art graphics processing units (GPUs) contain hundreds of processing units and are able to perform trillions of floating point arithmetic operations per second. The newly available computational power brought by GPUs is enabling a new generation of scientific and engineering applications to perform calculations on "personal supercomputers" that previously required HPC clusters or that were otherwise impractical in everyday use. This talk will present recent successes in multi-GPU acceleration in VMD, a molecular dynamics visualization and analysis application in which GPU computing techniques have provided speedups ranging from 10 to over 100 times faster than commodity CPU cores. The talk will describe key challenges and algorithmic strategies involved in achieving high computational performance on GPUs, discuss methods for effectively using multiple GPUs in low-latency calculations that drive interactive visualizations, and will also include some examples of how these performance increases ultimately enable better science.
