Cray-Cyber.org acquires two Cray J90 supercomputers

Begin of 2004, Cray-Cyber.org was able to acquire two Cray J90 supercomputers. A J932 was bought from Deutscher Wetterdienst (German Wheather Service). The machine is equipped with 32 vector CPUs, reaching a theoretical performance of 6.4 GFLOPs. The Institut für Meteorologie und Klimaforschung (Institute for meteorology and climate research) of Forschungszentrum Karlsruhe donated a J916. With 16 vector CPUs, this machine reaches a theoretical maximum at 3.2 GFLOPs. The machines came with disk subsystems and lots of documentation. Both systems were used for weather forecast and climate calculations

Cray-Cyber.org currently installs both machines for testing purposes. Only one machine will go online in the future. The other one will be used for spare parts.

Cray-Cyber.org is a subproject of GFHR e. V. The association has it's main focus on restoring and running ancient computer systems and preserve related knowledge in forms of documentation, hardware and software. Find more information on Cray-Cyber.org at www.cray-cyber.org.
