Water-stressed Globe Will Face Increased Thirst
Climate research shows Middle East and India at risk for greater water scarcity

By the end of the century, an increased demand for fresh water will hit the Middle East and India harder than other regions of the world, according to new research at PNNL. Projections analyzed by the researchers show that climate change will increasingly stress water availability, especially in already-dry regions.

Seeking Out Silent Threats to Simulation Integrity
Controlling the impact of soft errors on optimization algorithm results

Large-scale computing has become a necessity for solving the nation's most intractable problems. Due to their sheer number of cores, high-end computers increasingly exhibit intermittently incorrect behaviors-referred to as "soft errors"-placing the validity of simulation results at risk. A team of scientists at Pacific Northwest National Laboratory investigated the impact of soft errors on a full optimization algorithm. The team found that without intervention, soft errors would invalidate simulations in a significant fraction of all cases. They also found that 95% of the soft errors can be corrected. The work is featured in the Journal of Chemical Theory and Computation.
