Explore a 21-minute technical conference talk from SK TECH SUMMIT 2023 focusing on HMSDK, a software solution for optimizing 2-Tier memory systems combining DRAM and CXL Memory. Learn about specialized APIs and libraries designed to help software developers efficiently utilize CXL memory, which works alongside DRAM DIMM to expand memory capacity and bandwidth in servers. Discover how HMSDK (Heterogeneous Memory SDK) provides APIs and libraries for allocating and deallocating data in both DRAM and CXL memory systems, while addressing the performance gap between CXL memory and DRAM DIMM. Understand the system's ability to optimize memory placement based on bandwidth and data access characteristics, maximizing overall system performance. Presented by Rak-ki Kim, a System Software engineer with 15 years of experience in operating systems and platform software development at SK Hynix, who currently leads the development of HMSDK to maximize data center performance through efficient CXL Memory utilization.
