New Computer Software Enables Rapid Response to Time-critical Emergencies

Argonne researchers demonstrated a new system, called SPRUCE (Special Priority and Urgent Computing Environment), at Supercomputing 2006 in November. The demonstration featured a hypothetical scenario in which immediate access was requested and granted to

Sharpening up legacy codes

A team from Argonne National Laboratory in the USA is developing a modern set of exascale computing simulation tools for the design and study of liquid-metal-cooled fast reactors. The simulation-based high-efficiency advanced reactor prototyping (SHARP) project at Argonne National Laboratory (ANL) is a multidivisional, collaborative effort to develop a modern set of design and analysis tools for liquid-metal-cooled fast reactors. The project’s modular approach allows users to attach new modules to legacy reactor analysis codes, thereby avoiding costly rewriting of codes while enabling the incorporation of new physics modules.

Argonne's MG-RAST metagenome analysis server passes 1-terabase milestone

MG-RAST, the metagenome analysis server developed and operated by researchers at Argonne National Laboratory and the University of Chicago, has reached a new milestone: 1 terabase (1,012 basepairs)

Birth of the Universe, Direct Numerical Simulations of Cosmological Reionization

In this video from SC11, Michael Norman (SDSC), Joseph Insley (ANL), and Rick Wagner (SDSC) describe a set of ground-breaking collaborative astrophysics simulations. Essentially, the visualizations depict the formation of the first galaxies, and what happened to the surrounding intergalactic gas when they lit up.

Meeting highlights applications of Nek5000 simulation code

Thirty researchers from around the world gathered for the first Nek5000 meeting, held at Argonne on December 9 and 10, 2010. The objective was to enable developers and users of Nek5000 to exchange information, address technical issues and share experiences in areas of common interest.

Formal Analysis of MPI-based Parallel Programs

Formal methods can play an important role in debugging and verifying MPI applications. Here, we describe existing techniques, including their pros and cons, and why they have value beyond MPI, addressing the general needs of future concurrency application developers who will inevitably use low-level concurrency APIs.
