The Magellan Project: Building High-Performance Clouds

Motivated by the success of the Magellan cloud computing evaluation project, Argonne has been transitioning the system from a testbed into a production-grade system and training more researchers in how to best exploit its capabilities. Another major focus is closing the performance gap between traditional HPC platforms and the OpenStack platform, a large-scale, open source cloud computing initiative.

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.

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.

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.

Researchers use the cloud to shed light on a long-standing mystery

The question was: how is it that the quarks spins' contributions to the proton spin is only a small fraction of what was expected?
