End-to-End Data Transfer Systems for 100 Gbps Networks and Beyond

SESSION: Doctoral Showcase - Early Research Showcase

EVENT TYPE: Doctoral Showcase - Early Research Showcases

TIME: 3:30PM - 5:00PM

SESSION CHAIR: Wojtek James Goscinski

Data-intensive applications place stringent requirements on the performance of both back-end storage systems and front-end network interfaces in modern multi-core servers. However, for transferring data at ultra-high-speed, for example, at 100 Gbps and higher, the effects of multiple bottlenecks along a full end-to-end path, have not been resolved efficiently. My research leverages remote direct memory access (RDMA) and non-uniform memory access (NUMA) technologies to fully utilize bare-metal performance of state-of-the-art hardware. Particularly, my research designs network protocols for data-intensive applications based on RDMA one-sided operations and asynchronous programming interfaces across both local and wide area networks in front-end systems, and a NUMA-aware cache mechanism to align cache memory with the local NUMA node and schedule I/O requests to those threads that are local to the data to be accessed in back-end storage systems. These designs and implementation can significantly improve the performance of end-to-end data transfer systems.
