The US DOE-sponsored workshop on Libraries and Autotuning for Petascale Systems, held from Aug. 10–12 in Tahoe City, California, just completed. Jack Dongarra, Keith Cooper, Kathy Yelick, and Rich co-organize this annual research meeting. Perhaps not surprisingly, the most contentious discussion took place on the definition of autotuning!
