Title: Digital Space
Speaker: Anant Agarwal, CSAIL, MIT
Abstract: The multicore trend is universal. Spanning embedded processors, desktop CPUs and DSPs, supercomputers and cloud computing, multicore processors offer a game-changing opportunity for improvements in power efficiency and processing performance. More than anything else, multicores have put on-chip interconnect front and center in terms of design attention, since it has a first order impact on multicore performance, power efficiency, and even ease of programming. This talk will provide the inside scoop on our experiences with on-chip interconnect in university research with the 16-core Raw multicore processor, in a commercial environment with Tilera's 64-core Tile processor, and conclude with some startling predictions for future 1000 core processors.
Bio: Anant Agarwal is a professor of Electrical Engineering and Computer Science at MIT and an associate director of the CSAIL Laboratory. He enjoys hacking on Websim, an online circuits laboratory (google MIT websim). He is also a founder and Chief Technology Officer of Tilera Corporation. Agarwal holds a Ph.D. (1987) in Electrical Engineering from Stanford University, and a bachelor's from IIT Madras (1982). His teaching and research interests include computer architecture, software systems, and VLSI. He served as Associate Director of the MIT Laboratory for Computer Science (LCS) between 1998 and 2003, and was a co-leader of the Oxygen Project. He led a group that developed Sparcle (1992), an early multithreaded microprocessor based on the SPARC architecture, and the Alewife machine, a scalable shared-memory multiprocessor (1993). He led the Raw project at MIT's CSAIL laboratory, which developed an early tiled multicore microprocessor for distributed instruction level parallelism (DILP) and streams (2002). Agarwal also led the VirtualWires project at MIT and founded several start-ups, including Virtual Machine Works, Inc. (now part of Mentor Graphics) and Tilera Corporation. Agarwal won the Maurice Wilkes prize for computer architecture in 2001, the Presidential Young Investigator award in 1991, and the Louis D. Smullin Award for teaching excellence at MIT in 2005. He holds a Guinness World Record for the largest beamforming acoustic microphone array (LOUD) based on the Raw multicore processor. He is a Fellow of the ACM, and an author of the textbook Foundations of Analog and Digital Electronic Circuits.
