HPC is transforming our everyday lives, as well as our not-so-ordinary ones. From nanomaterials to jet aircrafts, from medical treatments to disaster preparedness, and even the way we wash our clothes; the HPC community has transformed the world in multifaceted ways. For its 27th anniversary, the annual SC Conference will return to Austin, TX, a city that continues to develop new ways of engaging our senses and incubating technology of all types, including supercomputing. SC15 will yet again provide a unique venue for spotlighting HPC and scientific applications, and innovations from around the world. SC15 will bring together the international supercomputing community—an unparalleled ensemble of scientists, engineers, researchers, educators, programmers, system administrators and developers—for an exceptional program of technical papers, informative tutorials, timely research posters and Birds-of-a-Feather (BOF) sessions. The SC15 Exhibition Hall will feature exhibits of the latest and greatest technologies from industry, academia and government research organizations; many of these technologies making their debut in Austin. No conference is better poised to demonstrate how HPC can transform both the everyday and the incredible.
