The Distributed European Infrastructure for Supercomputing Applications (DEISA) and the Partnership for Advanced Computing in Europe (PRACE) combined their individual annual science symposia into a larger European high-performance computing (HPC) gathering. The DEISA PRACE Symposium 2009, which recently took place in Amsterdam, attracted almost 200 participants from more than 20 countries, including scientific users, HPC technology experts, and government representatives. The theme of this year’s symposium was “HPC Infrastructures for Petascale Applications.” The symposium featured speakers from different scientific communities, including the National Science Foundation and the Department of Energy in the United States, RIKEN in Japan, the Australian National University, and Russia’s Moscow State University. “High-performance computing is crucial for climate research to understand mechanisms of climate change and predict future climate change perturbed by human activities,” says CNRS research and climate modeling expert Sylvie Joussaume, the chair of the European Network for Earth System modeling. “The powerful computing is needed to understand and to predict extreme events and assess the regional impacts of the climate change on society and economy.”
