      abstract     = {The High-Q Club showcases applications which demonstrate
                      scalability to effectively utilise all 458752 cores of the
                      JUQUEEN 28-rack Blue Gene/Q system at Jülich Supercomputing
                      Centre. Since its establishment, a broad spectrum of codes
                      qualified for membership using up to 1835008 processes
                      and/or threads. An opportunity for additional application
                      teams to (im)prove their code scalability, assisted by
                      experts from JSC Simulation Laboratories, Cross-sectional
                      teams and technical support, was provided by the 2015
                      JUQUEEN Extreme Scaling workshop. Within the first 24 hours
                      of dedicated access to the entire resource, all 7
                      participating teams had adapted their codes and datasets to
                      exploit the massive parallelism and restricted node memory
                      for successful full-system executions. With the High-Q Club
                      membership now grown to 24 codes, we summarise program
                      coding and scaling characteristics focussing on the 7 codes
                      from the workshop.},
