Clouds' Role in Sunlight Stopping
Research shows type and frequency of tropical clouds important for simulations of surface energy impact

Clouds are energy traffic cops, controlling how much sunlight reaches Earth. PNNL researchers found that the sunlight stopping power of each type of typical tropical cloud and how frequently they occur must be accurately simulated in climate models. Otherwise, understanding of the true impact of clouds on the Earth's energy balance will be uncertain. While they found that tall storm clouds have the largest impact on the amount of incoming solar energy that reaches the surface, these are infrequent tropical visitors.

Energy Star
Novel models of HPC systems depict the interplay between energy efficiency and resilience

To improve overall energy efficiency and performance on future exascale computing systems, scientists from PNNL; University of California, Riverside; and Marquette University examined some advanced high-performance computing systems and determined undervolting that also leverages existing mainstream resilience techniques at scale to reduce power consumption improved system failure rates. The undervolting method does not require modifying existing hardware or using pre-production machines and has shown positive results toward achieving a cost-efficient, energy-savings implementation for the HPC field. The paper documenting this first-of-its-kind work, “Investigating the Interplay between Energy Efficiency and Resilience in High Performance Computing,” will be presented during the IPDPS 2015 conference’s technical program.
