Explore the intricacies of parallel paging and green paging in this 45-minute conference talk by Michael A. Bender from Stony Brook University. Delve into the challenges of efficiently sharing a cache among multiple parallel processors and discover optimal multi-core paging algorithms for optimizing both makespan and average completion time. Examine the fundamental connection between parallel paging and green paging, and learn about the O(log p)-competitive algorithms for online parallel paging. Investigate the green paging dilemma, reductions between green paging and parallel paging, and competitive ratios. Gain insights into the optimist versus pessimist approach in this comprehensive exploration of advanced paging concepts presented by the Society for Industrial and Applied Mathematics.
