Today: Prof. Ben Yoo Talk on Nanophotonic Potential for Energy Efficient Computing
Prof. S. J. Ben Yoo of UC Davis will discuss “Next Generation Computing Systems and Data Centers: Energy Efficient Large-Scale Computing with Nanophotonic Interconnects” at 1 p.m. Tuesday, May 29, in Bldg. 50A, 5032. This talk will address a clean-slate approach to realizing next-generation computing and data centers by exploiting co-designed nanophotonics and nanoelectronics. By introducing massively parallel, optically interconnected multi processors, and by exploiting innovative hardware and software solutions, Yoo’s work is pursuing orders of magnitude improvement in performance-per-watt in the next generation computing and data centers.
Here is the abstract for his talk:
“Today’s computing has been a great success. By some estimates, the amount of data being processed is doubling approximately every 12 months. At this accelerating pace, our data centers must handle ~1000 times more data in 10 years. However, today’s data centers consume megawatts of power and require massive power distribution and cooling infrastructures. The proposed ‘Center’ project involves a multi-disciplinary team of the following five thrusts: Thrust 1: Next Generation Data-Center Architecture; Thrust 2: Data Center Resource Management and Virtualization; Thrust 3: Co-Designed Nanophotonics and Nanoelectronics Technologies; Thrust 4: System-on-Chip Integration; Thrust 5: Testbed and Application Studies, and Project Evaluation. I will overview the Center project, discuss potential partnerships, and introduce our 10-year project plans involving 20 faculty and 40 students toward achieving the required improvement in the power efficiency in support of next generation data centers handling ~1000 times more data in 10 years.”
Yoo is a professor in of electrical engineering at UC Davis and a member of the UC Davis branch of CITRIS (Center for Information Technology Research in the Interest of Society). His research includes high-performance optical switching systems and nanophotonic-electronic systems integration for next-generation networking and computing systems. His recent demonstrations included optical label switching routers scalable to 42 petabit/sec aggregate capacity with 1000-fold improvement in performance/power efficiency. Prior to joining UC Davis in 1999, he was a senior research scientist at Bellcore, leading technical efforts in optical networking research and systems integration.
Coordinator Sought for CS Summer Student Program
Computing Sciences is looking for a volunteer to coordinate the summer student program. The primary responsibilities are to line up speakers for the brown bag talks, welcome students at the kickoff and encourage students to give talks at the end of the summer (and encourage supervisors to support students' participation in the program). If interested, contact your group lead or ALD Horst Simon.
May 31 Gathering to Wish HR’s Diane Heim Well in New Job
At 1:30 p.m. Thursday, May 31, CS staff are invited to gather and wish Diane Heim well in her new position with the Accelerator and Fusion Research Division (AFRD). The gathering will be held in the CS suite conference room, 50B-4321. After nearly seven years as an HR generalist with Computing Sciences, Diane decided to accept a 50-percent position to allow her to spend more time with her family.
CRD’s Kathy Yelick to Speak on Promises, Challenges of Multicore Computing
Kathy Yelick, head of the Future Technologies Group, will be one of seven speakers at a June 2 conference focusing on "Multicore -- the New Face of Computing: Promises and Challenges." The conference, co-sponsored by the Santa Clara Chapter of the IEEE Computer Society and the North America Taiwanese Engineers' Association (NATEA), will be held from 9 a.m. to 5 p.m. at Stanford University’s Clark Center Auditorium. The meeting is the eighth annual conference in the "New Frontiers in Computing Technology" series co-sponsored by the two groups for the Bay Area engineering community. The event features speakers from both academia and industry.
Yelick will give a presentation on "The Berkeley View: Applications-Driven Research in Parallel Programming Models and Architectures."
The conference will present a technical overview of the hardware and software issues involved in making effective use of multicore technology, including compilation, scalability graphics co-processing and potential applications in the new domain.

About Computing Sciences at Berkeley Lab
The Lawrence Berkeley National Laboratory (Berkeley Lab) Computing Sciences organization provides the computing and networking resources and expertise critical to advancing the Department of Energy's research missions: developing new energy sources, improving energy efficiency, developing new materials and increasing our understanding of ourselves, our world and our universe.
ESnet, the Energy Sciences Network, provides the high-bandwidth, reliable connections that link scientists at 40 DOE research sites to each other and to experimental facilities and supercomputing centers around the country. The National Energy Research Scientific Computing Center (NERSC) powers the discoveries of 7,000-plus scientists at national laboratories and universities, including those at Berkeley Lab's Computational Research Division (CRD). CRD conducts research and development in mathematical modeling and simulation, algorithm design, data storage, management and analysis, computer system architecture and high-performance software implementation. NERSC and ESnet are Department of Energy Office of Science User Facilities.
Lawrence Berkeley National Laboratory addresses the world's most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe. Founded in 1931, Berkeley Lab's scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the DOE’s Office of Science.
DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit science.energy.gov.
