From February 14 to 16, JSC organized the 2011 edition of its Blue Gene Extreme Scaling Workshop. Similar to the previous workshops in 2009 and 2010, the main focus were application codes able to scale-up during the workshop to the full Blue Gene/P system JUGENE which consists of 72 racks with a total of 294,912 cores { still the highest number of cores worldwide available in a single system. Interested application teams had to submit short proposals which were evaluated with respect to the required extreme scaling, application-related constraints which had to be ful lled by the JUGENE software infrastructure and the scientifi c impact that the codes could produce. The process was very competitive: Only 8 out of the submitted 15 high-quality proposals were selected. This report summarizes the results achieved in the workshop.
