CSEE Colloquium

Energy Efficiency in Large-Scale Computing

David Prucnal, PE
Advanced Computing Systems

*TO BE RESCHEDULED, ITE 227, UMBC

Data center power demand and energy consumption have grown substantially over the past 10-20 yrs. For high performance computing, power has become one of the main limiting factors. The Supercomputing Top500 List is now dominated by individual machines that demand nearly 10MW, which is equivalent to the technical load of an entire data center just 10 yrs ago. In addition these machines require another 5-10MW to power the necessary cooling systems. This talk will examine the power problem, and discuss some approaches to improving energy efficiency in large scale computing environments. In particular, it will look at demand side techniques for fully exploiting existing infrastructure, and at the use of immersion cooling.

Mr. Prucnal has been active as a Professional Engineer in the field of power engineering for over 25 yrs. Over the past 15 yrs. he has been involved with designing, building, and optimizing high-reliability data centers. He joined the Agency as a power systems engineer and was one of the first to recognize the power, space and cooling problem in high performance computing. He moved from the facilities engineering directorate to the research directorate to pursue solutions to the HPC power problem from the demand side versus the infrastructure supply side. Mr. Prucnal leads the Energy Efficiency Thrust within the Advanced Computing Systems research team. His current work includes Power-Aware Data Center Operation, and Immersion Cooling. He also oversees projects investigating single/few electron transistors, 3D chip packaging, low-power electrical and optical interconnects, and power efficiency through enhanced data locality.

Black and Gold? Try Green and Gold

Spend a few minutes in Patapsco Hall’s recently-completed addition, and you won’t have to be told it received one of the world’s top certifications for environmentally-friendly design. The large windows reduce the need for artificial light, the heating and cooling system automatically adjusts to your presence and you won’t have to look far to recycle your soda can.

But while all of those features helped the building earn a LEED Gold certification, perhaps the most innovative part of the building’s design is how it is helping shape the future. That’s because residential life is using the building as an opportunity to educate the campus about sustainability.

“We are committed not only to having facilities and practices that lead to a more sustainable future, but also to educating our residents so that they understand our commitment to sustainability and have opportunities to change the culture firsthand,” said Katie Boone, director of residential life.

Education and leadership on climate change are key underpinnings of the American College and University Presidents Climate Commitment, which President Hrabowski signed in 2007. Within three years, the university adopted a Climate Action Plan, which among other things, requires new construction to meet at least LEED Silver certification.

Patapsco Hall exceeded expectations for certification – and for student involvement. While the addition was still in the earliest stages of planning, residential life invited students to contribute to conversations about making the building environmentally friendly.

“I was primarily concerned with the green design of the project, the energy consumption of the building, ideas for day-lighting as well as energy conservation,” said Samuel Su ’11, biology, who proposed several ideas for building features at the meetings.  “Because the project was something outside of the scope of my academic studies, it really presented an opportunity to learn something else through self-study.” Su runs the green living website Verno, which he started with several other UMBC students in 2009.

All student ideas were considered; some, such as elimination of actively-cooled water fountains, were implemented, while others, such as liquid discussant waterfalls, were investigated but proved to be too costly. One of the most innovative ideas came from Olyssa Starry, a graduate student at UMBC at the time, who suggested setting up a permanent experiment on the building’s roof.  Building designers incorporated a 600 square foot “green roof” and an identical “white roof” area into the building’s plans, and data are collected from the water that drains from each section of roof.

“Working with them to incorporate research into the design was such a learning process,” said Starry, who is now completing her Ph.D. at the University of Maryland, College Park.  “The team did not need a lot of convincing [to implement the plan], and from what I understand that is not typical.”

Starry is using data from the roof as part of her dissertation, a model of green roof hydrology. The data also are available online – and will eventually be displayed on a screen in the Patapsco lobby – creating a valuable resource for students interested in hydrology, said Andy Miller, associate professor of geography and environmental systems.

“Having a monitoring site right here on campus collecting information in real time presents a great educational opportunity,” he said. “It’s always a great advantage for students to be able to get their hands on real data and to see where it came from.”

With more construction and renovation projects on the horizon, the lessons learned through this project will impact the future of sustainability on campus. The next construction project, the apartment community center, will include a green roof, and residential life is looking to harness students’ enthusiasm for sustainability through new programs, such as contests to see who can use the least electricity and a potential geography and environmental systems living/learning community.

“Ultimately,” Boone said, “it is really about partnering with students to engage and educate on sustainable practices.”

Janice Grant, Civil Rights activist and storyteller in the Center for Art, Design and Visual Culture’s touring humanities project, For All the World to Hear: Stories from the Struggle for Civil Rights, was interviewed for Baltimore Magazine this month. Grant speaks candidly about her experiences growing up in segregated Maryland, and the interview not only provides insight into her life at the time of the Civil Rights Movement, it provides a snapshot of what one can expect to hear at For All the World to Hear. Read the interview at Baltimore Magazine.

For All the World to Hear, is a community outreach project that features approximately a dozen area seniors who speak, write, perform and digitally publish personal stories about their struggle for civil rights, that debuted at UMBC in the fall. A full program will return to campus Friday, February 15. Find out more about the project, and discover other performance dates at foralltheworldtohear.org.
