Abstract

Abundant cores per chip will encourage a greater use of space sharing, where work stays on a group of cores for long time intervals. Virtual hierarchies can improve performance and performance isolation of space-shared workloads, while still supporting globally shared memory to facilitate dynamic partitioning and content-based page sharing.
