Minesh Patel awarded the DSN-2022 William C. Carter Award

We’re very honoured to announce that Minesh Patel has been awarded the DSN-2022 William C. Carter Award for his PhD Dissertation titled “Enabling Effective Error Mitigation in Memory Chips That Use On-Die Error-Correcting Codes“.  Congratulations Minesh!

About the award:
The William C. Carter Award recognizes an individual who has made a significant contribution to the field of dependable and secure computing throughout his or her PhD dissertation, and commemorates the late William (Bill) C. Carter, a key figure in the formation and development of the field of dependable computing. The award is jointly sponsored by the IEEE TC on Dependable Computing and Fault Tolerance (TCFT) and IFIP Working Group 10.4 on Dependable Computing and Fault Tolerance (WG 10.4), and presented annually at the DSN Conference.  Minesh received the award at DSN 2022 in Baltimore this week.
The selection committee awarded Minesh’s PhD thesis with the following recognition:
The committee considered that the thesis constitutes a ground-breaking work in the understanding and handling of state-of-the-art error correction techniques opaquely implemented inside the newest DRAM chips. These chips are widespread and, as they keep scaling down, they become more susceptible to disturbance errors. As a reaction, the DRAM industry is integrating Error Correction Codes (ECC) inside the DRAM devices, on the die, in a confidential and proprietary way, masking these errors from the systems using them and, thus, preventing a system-level error-processing optimization. For instance, large datacenters cannot use anymore the previously seen DRAM error rates to train predictive models of hardware failures, something they need to do. Dr. Patel’s work addresses this challenging problem through rigorous experimental analyses of more than 300 DRAM chips. This enables him not only to produce new statistical error models and tools, but also to build new system-level techniques to improve the chips error tolerance. This work has been published in top venues in computer architecture and dependable systems; two of these publications won a best paper award, including one at DSN 2019. It is also important to note that Dr. Minesh’s work has already accumulated close to 1000 citations and that his h-index is already at 16, highlighting his influence within these communities. Last but not least, Dr. Patel’s work has already had some industrial impact: several industrial research labs and major DRAM manufacturers have provided strongly positive feedbacks under various forms.

The thesis is well written and easy to read, even for non-experts in the field. The committee was impressed by the breadth and the depth of the numerous contributions made, as well as by the thoroughness and soundness of the experimental validations carried out. For these reasons, the committee decided to award the 2022 Carter Award to Dr. Minesh Patel.


Thesis background and moving forward:

Minesh started his PhD thesis at CMU under the supervision of Onur Mutlu, and continued his PhD research at ETH Zurich with Onur, following Onur’s move from CMU to ETH.  During his PhD work, Minesh carried out two internships at Microsoft, in Fort Collins, CO, and Redmond, WA, and three internships at Apple in Cupertino, CA.

Minesh defended his PhD thesis last October and is currently exploring options for what comes next.  His graduate work focuses primarily on improvements to memory systems and, going forward, he is interested in broader topics pertaining to cutting-edge computing systems and broadly interested in architecture/systems topics.  He is exploring options for a research position in an industry lab in the area of computer systems and architecture.  Read more on his personal webpage: https://www.mineshp.com.
