EBE Grad Seminar Weekly Talk: Dr. Suresh V. Garimella, President UVM
November 15, 2019 @ 1:10 pm - 2:00 pm
Title: Energy Use in Information and Communications Technologies: The Role of Thermal Management
Abstract:
Data centers account for a significant and growing fraction of the worldwide electricity demand, owing to the rapid proliferation of electronics and the associated digital data generation. Despite this rapid growth in total energy consumption, the largely ad hoc approaches to space conditioning in large data centers and server farms have led to unconscionable inefficiencies that are now driving information technology companies to seek ways to lower their overall energy footprint. The sheer magnitude of heat dissipation in these large-scale computing facilities is staggering, and calls for urgent improvement of data center cooling strategies, which consume a significant fraction of the total energy used at the facility level. In particular, technologies that allow for increases in the data center operating temperature have the potential to eliminate energy-intensive air-conditioning systems and enable year-round rejection of waste heat to the ambient. Liquid cooling offers a low-thermal-resistance heat-rejection approach that may enable such operation without increasing the temperature of the electronic devices. Embedding liquid coolant channels directly in electronic devices offers further potential improvement in efficiency and performance scaling by enabling dramatic changes in the system architecture, such as 3D chip stacking. This talk will review key challenges encountered in the thermal management of information technology equipment at different scales, from data centers down to small-scale portable electronics, as well as recent technological developments related to embedded liquid-cooling strategies that may enable significant energy savings and performance gains.

Dr. Suresh Garimella is the 27th president of the University of Vermont. He previously led complex and expansive portfolios at Purdue University, a top-ranked, flagship research university. As Purdue’s inaugural Executive Vice President for Research and Partnerships, Dr. Garimella led a $660 million per year research enterprise, achieving five consecutive years of record research funding. Dr. Garimella conceived and implemented an ambitious $250 million Life Sciences Initiative focused on Pillars of Excellence in integrative neuroscience and immunological sciences, complementing Purdue University’s existing strengths in drug discovery and plant sciences.
In 2018, Dr. Garimella was appointed by President Trump to the National Science Board, which oversees the National Science Foundation and also serves as an independent body of advisers to both the president and Congress on policy matters related to science, engineering and educating the next generation of scientists.
Dr. Garimella received his Ph.D. from the University of California at Berkeley, an M.S. from The Ohio State University, and a bachelor’s degree from the Indian Institute of Technology Madras.
