JUQUEEN is located at Jülich Supercomputing Centre (JSC), Forschungszentrum Jülich, Germany.
JUQUEEN has become an old lady. The successor system will arrive and be installed in the first half of 2018. More information about this system can be found in the press release “Who will follow JUQUEEN to the throne“.
