In a newly-posted interview, Wen-mei Hwu from the University of Illinois and the co-principal investigator on the Blue Waters project discusses how researchers are moving their HPC code over to GPUs.
We are at the point in the industry where just the computing power grows about two times every two years. But in terms of real application, often you are getting less than 40 percent.
