报告摘要：The rapidly increasing number of cores in modern processors and the difficulties in scaling DRAM-based main memory have led to a widening gap between processor and memory speeds. In this talk, I will discuss two recent trends to scale memory capacity vertically and horizontally. Vertical memory scaling explores new memory technologies, such as non-volatile memory, to increase memory capacity while providing the traditional byte-addressable programming interface in a DIMM package. Horizontal memory scaling seeks to decouple memory from the traditional memory bus through innovative interconnect technologies, e.g., Compute Express Link (CXL), to scale memory independently from the processor and allow for high-speed communication between CPUs and a wide range of memory devices, including DRAM, non-volatile memory, and accelerators. In this talk, I will discuss the challenges and opportunities in vertical and horizontal memory scaling and present our recent work on characterizing and optimizing the performance of Intel Optane persistent memory and tiered memory management.
