This Project Grant from the National Science Foundation's $167,504 Computer and Information Science and Engineering program aims to develop new algorithms and programming abstractions for server operating systems and network interface cards to improve network traffic scheduling in cloud data centers. With an award date of October 1, 2021 and completion by August 31, 2022, this research seeks to overcome current performance bottlenecks and enable multiple applications to drive network cards at high speeds up to line rates while meeting latency, throughput, and fairness objectives as well as infrastructure-wide utilization and efficiency goals. A $167,504 sub-award to the University of Wisconsin-Madison supports this research through network programming workshops for engineers, students, and underrepresented high school students. The overall goal is to improve scalability, utilization, and efficiency of cloud computing infrastructure.
