Supercomputing 2007 Storage Challenge Finalist

MPICH2 (Argonne National Laboratory) and mpiBLAST (Virginia Tech) have collaborated using the ParaMEDIC framework to land a finalist slot in the SC07 storage challenge. MPICH2 powers ParaMEDIC (short for Parallel Metadata Environment for Distributed I/O and Computing), allowing it to accelerate mpiBLAST by as much as 25-fold in a distributed I/O and computing environment.

Ian Foster Named One of the Top Three Contributors to Computer Science

Argonne researcher Ian Foster has been named one of the top three contributors to computer science, according to a recent article in Nature. The ranking is based on the so-called h-index, introduced by physicist Jorge Hirsch in 2005 to rank the quality of a researcher's work. Foster is internationally renowned for his technical contributions and leadership in Grid computing, which was named "Most Promising New Technology" by R&D Magazine in 2002 and was cited by MIT Technology Review in 2003 as one of "Ten Technologies That Will Change the World."

Mihai Anitescu Presents a Semi-Plenary Address at ICCOPT

Mihai Anitescu, a computational mathematician at Argonne National Laboratory, will present a semi-plenary address at the Second Mathematical Programming Society International Conference on Continuous Optimization August 13-16, 2007, in Hamilton, Ontario. ICCOPT, held every three years, is the world's most prestigious conference in continuous optimization.

Anitescu's presentation,"Emerging Design Challenges in the Advanced Nuclear Fuel Cycles," will address the challenges and Argonne's recent results in optimization of complex systems and in particular optimization of the advanced nuclear fuel cycle.

Picture This: Visualization as a Tool for Data Analysis

As science becomes increasingly digitized and data-based, visualization is set to become more and more important. Using visualization, Gaither and Papka can help scientists from all fields: medical science, cosmology, computational fluid dynamics, architecture, geosciences and meteorology.

The biggest challenges, according to both Papka and Gaither, are visualizations of very abstract systems. In such cases collaborating with scientists and learning about the research domain is crucial to creating useful visualizations.

Argonne Wins Three R&D 100 Awards for Innovative Technologies

The Access Grid is one of three Argonne projects to win R&D Magazine's prestigious award this year. Access Grid 3 software enables groups of people to collaborate using open- source standards and Internet technology. The Access Grid is designed to provide a natural virtual environment, where users can see and hear one another, projected on a large display wall. More than just videoconferencing, the Access Grid enables participants to share and interact with files and applications. The open nature of the Access Grid software has attracted thousands of users from around the world and has encouraged numerous commercial and research institutions to adopt the software for their purposes.
