JUGENE, an IBM Blue Gene/P system, was operated in several phases vom 2007 to 2012. The 72-rack system which went into production in July 2009 reached the 3rd place on the TOP500 list of June 2009.
JUROPA (Jülich Research on Petaflop Architectures) and the complementing system HPC-FF (High Performance Computing for Fusion) were in production between August 2009 and June 2015. HPC-FF was a special system dedicated for the plasma physics community of Europe.
JUROPATEST (Jülich Research on Petaflop Architectures) was a test system to allow users of JSC's general purpose supercomputer JUROPA for porting and optimising their applications for the new Haswell CPU architecture. The system also served as a development platform for system software and hardware with respect to the JUROPA collaboration.
QPACE (Quantum Chromodynamics Parallel Computing on the Cell) was a massively parallel and scalable computer architecture optimized for lattice quantum chromodynamics (LQCD). It was operated at JSC between November 2009 and October 2016
