Rethinking Processor and System Architecture
University of Washington

Modern technology presents chip designers with challenges that will fundamentally alter how processors work and how we design all aspects of computer systems. The first portion of my talk presents a dataflow-style processor architecture, WaveScalar, that is simpler to design, more scalable, and, in many cases, better performing than conventional processors. WaveScalar provides a unique hybrid memory interface that supports programs written in imperative languages (C, C++, Java, etc.) and allows programmers to explicitly express memory parallelism. WaveScalar also provides a flexible multi-granular threading facility and allows programmers to mix thread granularities and memory interface styles in a single program to express parallelism where it is available. The WaveScalar processors provide a substrate of simple processing tiles, a hierarchical on-chip network, and a high-bandwidth memory system. I will present data demonstrating that scaling the size of a WaveScalar design by a factor of 10 results in a commensurate 10-fold increase in performance and that WaveScalar designs outperform conventional chip-multiprocessor designs by a wide margin. The second part of the talk builds on my experience designing WaveScalar to explore the larger question of how architectures should affect (and be affected by) programming languages, software engineering practices, and overall system architecture.

Hosted by Dirk Grunwald.
The speaker is a candidate for a faculty position in the Department of Computer Science.


The Department holds colloquia throughout the Fall and Spring semesters. These colloquia, open to the public, are typically held on Thursday afternoons, but sometimes occur at other times as well. If you would like to receive email notification of upcoming colloquia, subscribe to our Colloquia Mailing List. If you would like to schedule a colloquium, see Colloquium Scheduling.

Sign language interpreters are available upon request. Please contact Stephanie Morris at least five days prior to the colloquium.
