CXL and the Art of Hierarchical Memories: Their Management and Use
New technologies and platforms have laid waste to the assumptions of fixed-size, monolithic memory. Multiple layers of CXL-attached memory and persistent memory now provide a wide variety of types and speeds of memory available to developers of future systems. We will compare these various tiers of memories, whether inside the box or remotely attached. Next, we will examine how users and consumers of multi-tiered memory can make use of their varying characteristics, such as latency and persistence.
