Best Paper Award at ICPP 2010 Conference

Researchers from the Jülich Supercomputing Centre received the Best Paper Award from the International Conference on Parallel Processing (ICPP) 2010 in San Diego, California, a forum for scientists and engineers in academia, industry and government to present their latest findings in parallel and distributed computing. The award was given to the authors David Böhme, who is funded through a scholarship from the RWTH graduate school AICES, Dr. Markus Geimer, Prof. Felix Wolf, and Dr. Lukas Arnold for their paper entitled "Identifying the root causes of wait states in large-scale parallel applications". The article introduces a scalable technique that enables an improved understanding of how the effects of load imbalance slow down program execution - a well-known problem with many simulation programs that prevents them from exploiting the full power of large and expensive supercomputers such as JUGENE. The new approach, which is currently being integrated into Scalasca, a widely-used performance-analysis tool developed at the Jülich Supercomputing Centre and the German Research School for Simulation Sciences in Aachen, will allow more target-oriented optimizations of such phenomena.
