ESnet Receives $62 Million to Develop World's Fastest Computer Network

ESnet is receiving $62 million to develop what will be the world's fastest computer network, designed specifically to support science. Funded by the American Recovery and Reinvestment Act, the Advanced Networking Initiative will ensure that the United States stays competitive in science and technology. More>

NERSC Awards Supercomputer Contract to Cray

NERSC announced that a contract for its next generation supercomputing system will be awarded to Cray Inc. When completed, the system will deliver a peak performance of more than one petaflops, equivalent to more than one quadrillion calculations per second. The system will be named Hopper, after American computer scientist Grace Hopper. More>

Increase in IO Bandwidth to Enhance Future Understanding of Climate

Researchers at Pacific Northwest National Laboratory—in collaboration with NERSC, Argonne National Laboratory, and Cray—recently achieved an effective aggregate IO bandwidth of 5 gigabytes/sec for writing output from a global atmospheric model to shared files on DOE's "Franklin," a 39,000-processor Cray XT4 supercomputer located at NERSC. The work is part of a Science Application Partnership funded under DOE's SciDAC program. More>

CRD Receives Funding to Develop Tools for Science Research

CRD researchers will receive funding to develop tools that will monitor workflows on distributed systems, as well as enhance scientific collaboration by providing an end-to-end resource provisioning and management system for HPC data transfers. More>

ASCR Discovery: Code Controls Communication to Boost Computer Performance

As high-performance computers bring more power to programmers, communication often limits an operation's overall speed. NERSC Director Kathy Yelick and Paul Hargrove of the Berkeley Lab's Computing Sciences Division discuss how Unified Parallel C (UPC) resolves some of the shortcomings of Message Passing Interface (MPI).

Scientific Computing: Smashing the Trillion Zone Barrier

As computational scientists are confronted with increasingly massive datasets, one of the biggest challenges is having the right tools to gain insight from the data. In this article for Scientific Computing, Hank Childs writes that VisIt may be up to the challenge. Childs is a member of the Berkeley Lab Computing Sciences Analytics and Visualization Group and architect of VisIt—one of the most popular frameworks for data analysis and scientific visualization.
