SC is the International Conference for
High Performance Computing, Networking,
Storage and Analysis

SCHEDULE: NOV 12-18, 2011

When viewing the Technical Program schedule, on the far righthand side is a column labeled "PLANNER." Use this planner to build your own schedule. Once you select an event and want to add it to your personal schedule, just click on the calendar icon of your choice (outlook calendar, ical calendar or google calendar) and that event will be stored there. As you select events in this manner, you will have your own schedule to guide you through the week.

You can also create your personal schedule on the SC11 app (Boopsie) on your smartphone. Simply select a session you want to attend and "add" it to your plan. Continue in this manner until you have created your own personal schedule. All your events will appear under "My Event Planner" on your smartphone.

“Hot” for Warm-Water Cooling

SESSION: “Hot” for Warm-Water Cooling

EVENT TYPE: Birds of a Feather

TIME: 5:30PM - 7:00PM

SESSION LEADER(S):William Tschudi, David Martinez, Farhad Banisadr

ROOM:WSCC 613/614

About half of an air-cooled data-center's energy consumption is wasted on powering the cooling systems that keep the computer system from overheating. Furthermore, the amount of heat dissipated by future supercomputers limits the practicality of air-cooling. Liquid-cooling is key to reducing cooling energy consumption for future supercomputers because the heat capacity and transfer efficiency of liquids is orders of magnitude greater than that of air. The transition from air to liquid-cooling is a technology inflection point providing an opportunity to set guidelines for energy efficiency of liquid-cooled facilities and systems. Substituting vapor-compression refrigeration systems with cooling towers or dry coolers that provide warmer water to supercomputers is the natural progression towards energy conservation. The U.S. Department of Energy (DOE) Supercomputing Laboratories are working collaboratively with industry representatives to develop guidelines for warmer liquid-cooling temperatures to guide future supercomputer procurements, and to facilitate the design of warmer temperature cooling systems.
