CRUISE: Cache Replacement and Utility-Aware Scheduling

When several applications are co-scheduled to run on a system with multiple shared LLCs, there is opportunity to improve system performance. This opportunity can be exploited by the hardware, software, or a combination of both hardware and software. The software, i.e., an operating system or hypervisor, can improve system performance by co-scheduling jobs on LLCs to minimize shared cache contention. The hardware can improve system throughput through better replacement policies by allocating more cache resources to applications that benefit from the cache and less to those applications that do not.
