SC15 Working Group BoF Presentations
Identifying a Few, High-Leverage Energy Efficiency Metrics?
Abstract:
How do we bring speed, clarity and objectivity to energy management in HPC centers? What are usage models and key metrics for current and envisioned energy information systems? What are metering requirements (what sensors and meters at which points and at what measurement frequency)? These are timely and critical questions for System Administrators, Operations and Facilities Managers and End-users. The purpose of this BoF is to review and provide feedback on a collaborative effort to identify requirements for HPC Data Center energy information systems. The BoF will host a panel of seasoned administrators and managers, followed by lively audience discussion.

Website Survey Questions:
We are still soliciting responses to the survey to provide feedback on proposed energy efficiency metrics: One for the HPC Center Operations Manager, another for the HPC Center Facilities Manager and the last for the HPC Center System Administration Manager. Rate each of the metrics as to its priority (high, medium or low).

Dynamic Liquid Cooling, Telemetry and Controls; Opportunity for Improved TCO
Abstract:
Today’s practice for liquid cooling is to use CDUs with constant flow-rate and temperature. Tomorrow’s products could be designed for variable flow-rate and temperature based on actual heat removal requirements, but there would have to be more and finer grained telemetry and controls. How much savings can be gained in energy savings compared to the incremental capital and operational costs? Application load differences can cause rack power variation, but nodes within a rack can also vary. Where is the sweet spot for implementation- at the rack, node or even component level? This BoF will address these and other related questions.
