Outstanding Doctoral Dissertation Award

2021 Outstanding Dissertation Award


ACM's Special Interest Group on High Performance Computing (SIGHPC) is pleased to announce that Dr. Rohit Zambre of the University of California, Irvine has won the 2021 SIGHPC Doctoral Dissertation Award. This award is given each year for the best doctoral dissertation completed in high performance computing (HPC) in the previous year, and includes a $2,000 cash prize, a plaque, and recognition at the International Supercomputing Conference (SC’XY) in November. Nominations were evaluated on technical depth, the significance of the research contribution, the potential impact on theory and practice, and overall quality of work.

This year’s award is presented for outstanding contributions to the design, development, and measurement of a new MPI+threads library for scalable communication of multithreaded applications on current supercomputers. Dr. Zambre’s dissertation, titled “Exascalable Communication for Modern Supercomputing,” analyzes the decade-long problem of slow multithreaded communication in supercomputing applications, and eliminates the communication bottleneck by bridging the two ends of the HPC stack – MPI library developers and domain experts – that typically do not talk to each other directly. Dr. Zambre collaborated with MPI library developers at Argonne National Laboratory to make high-speed multithreaded communication a reality (ICS’20), and he collaborated with developers of applications targeted to run on the upcoming exascale machines to achieve significant performance improvements by utilizing the new MPI library (TPDS’21).SIGHPC's Outstanding Doctoral Dissertation Award is given for an outstanding doctoral dissertation completed in high performance computing (HPC). This award is open to students studying anywhere in the world who have completed a PhD dissertation with HPC as a central research theme.

About the Award:

This award is open to students studying anywhere in the world who have completed a PhD dissertation with HPC as a central research theme. In this case, HPC refers to the study or application of computational capabilities delivering much higher performance or larger scales than could be accomplished with a desktop or simple server system in order to solve large problems. Nominations for the next Doctoral Dissertation Award will open in August 2021.

To qualify for the Outstanding Doctoral Dissertation Award, the dissertation must:

  • Have been successfully defended (or accepted by the committee if no defense is required) during the calendar year

  • Be submitted in the final form that was accepted by the department

  • Be submitted in English

The award is presented during the annual SC conference. The awardee is recognized with a $2,000 cash prize, a plaque, and travel support to SC.
