Architecting Efficient Interconnects for Large Caches
Future multi-core chips will allocate a large fraction of chip area to support multi-megabyte cache hierarchies. Complex on-chip networks will be required to connect the many cores and cache banks in such a chip. The on-chip network plays a significant role in determining overall processor performance and power. The talk will first describe the creation of a tool (CACTI 6.0) that carefully considers on-chip network parameters in estimating an optimal cache organization. It will then discuss novel mechanisms to improve the performance and power of the on-chip network.

Bio: Rajeev Balasubramonian received his B.Tech in Computer Science and Engineering from the Indian Institute of Technology, Bombay in 1998. He received his MS (2000) and Ph.D. (2003) degrees from the University of Rochester. He joined the faculty at the School of Computing, University of Utah in August 2003. His primary research areas include memory hierarchies, on-chip interconnects, reliability, and 3D die stacking. Dr. Balasubramonian is a recipient of the NSF CAREER award and multiple teaching awards from the University of Utah. As a graduate student, he received the IBM Ph.D. Fellowship and the University of Rochester Sproull Fellowship. Refreshments provided at 10:45
