Managing Memory Tiers with CXL in Virtualized Environments

Explore a 16-minute conference talk from USENIX OSDI '24 on managing memory tiers with CXL in virtualized environments. Dive into the challenges and solutions for deploying CXL-based memory in cloud environments, focusing on the trade-offs between increased capacity and higher latency. Learn about Intel® Flat Memory Mode, a hardware-managed tiering system for CXL, and its performance implications across various workloads. Discover Memstrata, a lightweight multi-tenant memory allocator designed to address inter-VM contention and improve performance for VMs sensitive to hardware tiering. Gain insights into the latest research on optimizing memory management in virtualized cloud environments, balancing performance, cost, and energy efficiency.
