Co-developer of the publicly distributed Rice Simulator for ILP Multiprocessors (RSIM), Ranganathan contributed to what was at that time the only publicly-distributed software for simulating shared-memory multiprocessors with state-of-the-art instruction-level-parallel (ILP) processors.
A Fellow at Hewlett Packard Labs, Ranganathan has led a research program on future green computing data-centric data centers. His research interests are in systems architecture and manageability, energy-efficiency, and systems modeling and evaluation. He has done extensive work in these areas including key contributions around energy-aware user interfaces, heterogeneous multi-core processors, power capping and power-aware server designs, federated enterprise power management, energy modeling and benchmarking, disaggregated blade server architectures, and most recently, storage hierarchy and systems redesign for non-volatile memory.
He was also one of the primary developers of the publicly distributed Rice Simulator for ILP Multiprocessors (RSIM) Version 1.0, August 1997. RSIM was at that time the only publicly-distributed software for simulating shared-memory multiprocessors with state-of-the-art instruction-level-parallel (ILP) processors, with over 2000 licenses worldwide. RSIM contains more than 51,000 lines of C++ code spread over 120 files.
His work has led to several commercial products and has been featured in various venues including the New York Times, Wall Street Journal, Business Week, San Francisco Chronicle, Times of India, Slashdot, Youtube, and Tom's Hardware Guide. Ranganathan was named one of the world's top young innovators by MIT Technology Review, and has been recognized with several other awards including Rice University's Outstanding Young Engineering Alumni award. He received his B.Tech degree from the Indian Institute of Technology, Madras and his M.S. and Ph.D. from Rice University, Houston.
His publications included: "Datacenter-scale Computing," Luiz Barroso and Parthasarathy Ranganathan, IEEE Micro Special Issue on Datacenters, 2010; and "Sustainability-aware Design of Green Datacenters," Amip Shah, IMECE, 2010, with Cullen Bash, Jichuan Chang, Justin Meza. Among his numerous awards, Ranganathan was a 2011 recipient of the Distinguished Scientists award by the Association for Computing Machinery (ACM). The Distinguished Member Grade ACM Award recognizes those ACM members with at least 15 years of professional experience and 5 years of continuous Professional Membership who have achieved significant accomplishments or have made a significant impact on the computing field.
