CXL SIG (Disaggregated Memory) @ SSRC

CXL SIG (Disaggregated Memory)

In that open forum with current¹ (and future², hopefully) CRSS members, we are exploring software and system architecture evolution around the trend of Memory Disaggregation.

Why CXL and Disaggregation?
Microarchitecture Co-evolution with CXL (ISAs, Caches, PNM)
Linux HMM scope, co-evolution with CXL, and limitations

Status

Current Stage

Survey and Research Problem Definition
Tracking industry developments and emerging requirements with industry participants

Next Up

Measurement, Modeling and Simulation of Workloads and Systems with Disaggregated Memory
