Titan Gets Computational Company
November 01, 2013 — Two new computing resources are being installed at the Oak Ridge Leadership Computing Facility (OLCF) to enhance the user experience and maximize project outputs. The new machines will help scientists consolidate the massive amount of data gathered from Titan, allowing researchers to find answers to some of the world’s most puzzling problems.
Conformational Diversity and Sub-states in Enzyme Catalysis
November 01, 2013 — Enzymes are great biocatalysts, and have attracted significant interest for industrial applications (including cellulosic ethanol) due to their remarkable catalytic efficiencies. The understanding of factors that enable enzymes to achieve the high catalytic efficiency will have large impact through design of new and powerful biocatalysts.
Tracking a Value's Influence on Later Computation
November 01, 2013 — Understanding how a program behaves is important for effective program development, debugging, and optimization, but obtaining the necessary level of understanding is usually a challenging problem. One facet of this problem is to understand how a value (the content of a variable at a particular moment in time) influences other values as the program runs.
Using Performance Tools to Support Experiments in (HPC) Resilience
November 01, 2013 — The high performance computing (HPC) community is working to address concerns associated with fault tolerance and resilience in current and future large scale computing platforms. This is driving enhancements in the programming environments, specifically research on enhancing message passing interface (MPI) to support fault tolerant computing capabilities.
Optimizing Blocking and Nonblocking Reduction Operations for Multicore Systems: Hierarchical Design and Implementation
November 01, 2013 — This work proposed a design for implementing blocking and non-blocking reduction collective operations for modern multicore systems. An implementation based on the design performed an order of magnitude better than the state of-the-art on variety of systems including Cray and InfiniBand systems.
Titan’s New Build Attracts Magnetic Systems Research Impossible Until Now
November 01, 2013 — As simple as magnets seemed during school science lessons (opposites attract, likes repel), improving the performance of magnetic materials and creating new alloys is so complicated Markus Eisenbach, computational scientist at Oak Ridge National Laboratory, has been waiting for a computer that can perform as many as twenty quadrillion calculations per second to help do the job.
ForWarn Researchers Get EVEREST-Sized Look at Woodland Disturbances
November 01, 2013 — An exploratory visualization facility at Oak Ridge National Laboratory has provided researchers with the Forest Service Eastern Forest Environmental Threat Assessment Center and their partners a unique view of maps used for detecting and tracking unexpected forest change and disturbances.
