DescriptionReconfigurable Supercomputing (RSC) is characterized by hardware that adapts to match the needs of each application, offering unique advantages in performance per unit energy for high-end computing. 2017 continues breakout for RSC. Last year’s highlights included datacenter deployment by Microsoft, acquisition of Altera by Intel, and successful large-scale RSC in the NSF CHREC Center. This year is highlighted by deployment of publicly available RSC nodes and clusters by AWS and Baidu. This BoF introduces architectures of such systems, describes applications and tools being developed, and provides a forum for discussing emerging opportunities and issues for performance, productivity, and sustainability.
