University of Bristol postdoctoral researcher Rio Yokota was a member of the team that won the first Gordon Bell prize in the price per performance category of high-performance computing since 2001 at the recent SC09 conference. Rio Yokota carried out the programming remotely, while the actual calculations were run on a cluster of graphics processing units (GPUs) at Nagasaki University. At Bristol, Yokota is developing the fast multipole method for GPUs with a group led by Lorena Barba in the Department of Mathematics. Yokota collaborated with researchers in Japan, and in November the team reached a sustained performance of 57.3 teraflop per second (Tflops) on a cluster of 760 GPUs that cost $428,134.
At 138 megaflops per dollar, the mark is 32 times better than the achievement of the 2001 price per performance winner. The level also is an increase from the 42 Tflops performance Yokota and colleagues recorded in a paper published in August 2009.
