Paper Title: Software Defined Memory (SDM) with Faster Interconnects and Tiered Memory

Paper Abstract: Software-Defined Memory (SDM) is an emerging architecture paradigm that provides software abstraction between applications and underlying memory resources with dynamic memory provisioning to achieve the desired SLA. With the emergence of newer memory technologies and faster interconnects, it is possible to optimize memory resources deployed in cloud infrastructure while achieving best possible TCO. SDM provides a mechanism to pool disjoint memory domains into a unified memory namespace. This talk will cover SDM Architecture, the current industry landscape, academic research, and leading use cases (e.g. Memcached, databases etc.) that can benefit from SDM design. It will also will cover how applications can consume different tiers of memory (e.g., DDR, SCM, HBM) and interconnect technologies (e.g. CXL) that are foundational to the SDM framework in order to provide load-store access for large scale application deployments. The SDM value proposition will be demonstrated with caching benchmarks and tiering to show how memory can be accessed transparently.
