New ASCR Report Gets Big Lift from PNNL
Data Crosscutting Requirements is a report resulting from an Advanced Scientific Computing Research-sponsored workshop held in April 2013 to assess data requirements associated with DOE-sponsored scientific facilities and large-scale experiments. PNNL was a major contributor to the organization of the workshop and the finalized report.

PNNL's 2013 Key Scientific Accomplishments report is now available. This full-color report highlights discoveries and solutions advancing scientific frontiers in biological, chemical, computational, materials, and physical sciences.
Seeking Out Silent Threats to Simulation Integrity
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.
Detecting the Secrets of the Universe Deep Underground
Working as part of a collaborative team, Pacific Northwest National Laboratory (PNNL) is bringing its signature capability in ultra-low-level detection to help search for a rare form of radioactive decay-never before detected-called "neutrinoless double beta decay" (0νββ) in germanium (76Ge). If observed, 0νββ would demonstrate neutrinos are Majorana-type particles. This discovery would show neutrinos are unique among fundamental particles, having a property whereby the matter and anti-matter version of this particle are indistinguishable.
Bora Akyol New IEEE Senior Member
In August 2013, Dr. Bora Akyol was named an Institute of Electrical and Electronics Engineers Senior Member, the highest grade for IEEE members. To become an IEEE Senior Member, candidates must demonstrate five years of significant performance in their scientific fields and be recognized by their peers for technical and professional excellence. Bora is a senior research scientist in CSMD's Data Intensive Scientific Computing group, focusing on research and development in network security, information sharing protocols, and Smart Grid. He also serves as cyber security lead for the Pacific Northwest Smart Grid Demonstration project.
