Onur Mutlu and Co-authors Receive the 2021 HPCA Test of Time Award

Posted on March 9, 2021March 12, 2021 by ewent

Congratulations to Onur Mutlu and co-authors on receiving the HPCA Test of Time Award for their 2003 HPCA paper:

Runahead Execution: An Alternative to Very Large Instruction Windows for Out-of-Order Processors
Onur Mutlu, Jared Stark, Chris Wilkerson, Yale N. Patt

The IEEE International Symposium on High-Performance Computer Architecture (HPCA) Test of Time Award recognizes the most influential papers published in prior sessions of HPCA (held 18-22 years ago), and that have had a significant impact in the field.

The paper was Professor Onur Mutlu’s first publication during his PhD at the University of Texas with his PhD advisor Professor Yale Patt and colleagues from Intel, and Dr. Jared Stark and Chris Wilkerson. The significance of the paper was described by the award committee as: “Runahead Execution is a pioneering paper that opened up new avenues in dynamic prefetching. The basic idea of run ahead execution effectively increases the instruction window very significantly, without having to increase physical resource size (e.g. the issue queue). This seminal paper spawned off a new area of ILP-enhancing microarchitecture research. This work has had strong industry impact as evidenced by IBM’s POWER6 – Load Lookahead, NVIDIA Denver, and Sun ROCK’s hardware scouting.” The award was presented last week at HPCA 2021 on March 2, 2021.

Talk: Intelligent Architectures for Intelligent Machines Oct 7

Posted on October 5, 2020October 6, 2020 by ewent

Join Onur for his online talk in the HKUST Engineering x HKSTP Distinguished Speaker Series on Oct 7 at 11:00 CEST (Zurich time).

You can register here: https://calendar.ust.hk/events/hkust-engineering-x-hkstp-distinguished-speaker-series-webinar-intelligent-architectures

Computing is bottlenecked by data. Large amounts of application data overwhelm storage capability, communication capability, and computation capability of the modern machines we design today. As a result, many key applications’ performance, efficiency and scalability are bottlenecked by data movement.

Jointly hosted by SENG, HKUST AI Chip Center for Emerging Smart Systems and Hong Kong Science and Technology Parks Corporation, this webinar features a renowned computer architecture expert, Prof. Onur Mutlu from ETH Zurich. We will discuss the major shortcomings of modern architectures, the recent research that could enable computation close to data, as well as the guiding principles for future computing architecture and system designs. (Please click here for more information.)

Moderated by Prof. Tim Cheng, Dean of Engineering, register to get more insights on how intelligent architecture could be designed to handle data well.
