Energy-Aware Performance Scaling in the Petascale Regime

Many large scale modeling and simulation applications are based on sparse numeric and symbolic computations. As we approach petascale computing regimes, power, energy and cooling costs continue to skyrocket with a widening gap between actual execution rates on realistic sparse scientific workloads and the peak on tuned dense kernels. We discuss how interactions between code and computer architecture features can be exploited to enable energy-aware, high performance for sparse scientific computations. In the near term, it can lead to adaptive techniques for reducing dynamic power without impacting performance. In the longer term, it could provide insights for the design of energy-aware high performance hardware architectures.

This talk is sponsored by the National Center for Atmospheric Research Computational & Information Systems Laboratory and will be held in the Main Seminar Room at the Mesa Lab.


The Department holds colloquia throughout the Fall and Spring semesters. These colloquia, open to the public, are typically held on Thursday afternoons, but sometimes occur at other times as well. If you would like to receive email notification of upcoming colloquia, subscribe to our Colloquia Mailing List. If you would like to schedule a colloquium, see Colloquium Scheduling.

Sign language interpreters are available upon request. Please contact Stephanie Morris at least five days prior to the colloquium.
