Reexamining Direct Cache Access to Optimize I-O Intensive Applications for Multi-hundred-gigabit Networks

The course aims to explore the impact of cache management on the performance of I/O intensive applications, specifically focusing on direct cache access (DCA) and Data Direct I/O technology (DDIO) in Intel processors. The goal is to optimize DDIO-enabled systems for I/O intensive applications, demonstrating potential latency reductions of up to ~30% at 100 Gbps. The course covers topics such as the workings of DDIO, LLC ways used by DDIO, tuning DDIO for performance, and the implications of DDIO on processing time. The intended audience includes system designers, developers, and individuals interested in optimizing systems for multi-hundred-gigabit networks.
