Hello all-- A final reminder: Prof. Josep Torrellas from UIUC will be visiting Princeton and giving a seminar on Tuesday April 30. The seminar will be from 12:30-1:30 in CS Room 302, with pizza beforehand starting at noon. Title/abstract below. I have reserved a 1-hour slot for him to meet with grad students from 2:30-3:30pm that day. That will occur in CS room 401. Any interested grad students can feel free to just show up for that. Thanks, Margaret ----------------------------------------------------------------- Toward Programmable High-Performance Multicores Josep Torrellas University of Illinois, Urbana-Champaign http://iacoma.cs.uiuc.edu/~torrellas One of the biggest challenges facing us today is how to design parallel architectures that attain high performance while efficiently supporting a programmable environment. In this talk, I describe novel organizations that will make the next generation of multicores more programmable and higher performance. Specifically, I show how to automatically reuse the upcoming transactional memory hardware for optimized code generation. Next, I describe a prototype of Record&Replay hardware that brings program monitoring for debugging and security to the next level of capability. I also describe a new design of hardware fences that is overhead-free and requires no software support. Finally, if time permits, I will outline architectural support to detect sequential consistency violations transparently. BIO: Josep Torrellas is a Professor of Computer Science and Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign (UIUC). He is a Fellow of IEEE and ACM. He is the Director of the Center for Programmable Extreme-Scale Computing, a center funded by DARPA, DOE, and NSF that focuses on architectures for extreme energy and power efficiency. He also directs the Intel-Illinois Parallelism Center (I2PC), a center created by Intel to advance parallel computing in clients. He has made contributions to parallel computer architecture in the areas of shared-memory multiprocessor organizations, cache hierarchies and coherence protocols, thread-level speculation, and hardware and software reliability. He received a Ph.D. from Stanford University. ------------------------------------------------------------ Margaret Martonosi Hugh Trumbull Adams '35 Professor of Computer Science Princeton University http://www.princeton.edu/~mrm mrm@princeton.edu
