Stony Brook University alumni Yufei Ren has been selected the winner of the 2015 Standard Performance Evaluation Corporation (SPEC) Distinguished Dissertation Award, which is given each year to a doctoral dissertation that exemplifies scientific significance, impact and originality. He was chosen from among 15 phenomenal dissertations from institutions worldwide.
Ren earned his PhD from the Department of Electrical and Computer Engineering and is a member of the Institute of Advanced Computational Science at Stony Brook. Ren’s thesis advisor Dantong Yu nominated his dissertation, Scalable End-to-End Data I/O over Enterprise and Data-Center Networks, for the SPEC honor. Ren’s thesis committee also included professors Michael Bender, Shudong Jin, Yuanyuan Yang and Fan Ye.
Ren conducted his research at Brookhaven National Laboratory under the Computational Science Initiative. His dissertation focuses on an intelligent hybrid approach of system off-load and the Non-Uniform Memory Access (NUMA) aware scheduling to improve data I/O (input/output), data sharing and data streaming.
Ren’s research resulted in a middleware that takes advantage of Remote Direct Memory Access (RDMA) techniques to attain high network throughput. As a result of this middleware, an RDMA-based File Transfer Protocol service, RFTP, is now available for public evaluation and use. His work lays a foundation for the joint effort between Brookhaven Lab and Stony Brook to pursue the Department of Energy’s exascale initiative that is essential and transformative, and provides quantum advances in areas of science, technology and sustainable society. In particular, Ren provides a promising solution of data communication that is commensurate with exascale computing. His work at Brookhaven was supported through US Department of Energy grants.
Now working as a research scientist at IBM T.J. Watson Research Center, Ren is not the only scientist from Stony Brook to win this award. In 2013, SPEC chose Anshul Gandhi’s dissertation on Dynamic Server Provisioning for Data Center Power Management. Gandhi is an assistant professor of computer science at Stony Brook, and he also worked at the IBM T.J. Watson Research Center.
