The system was designed by experts from the Jülich Supercomputing Centre and implemented together with the partner companies Bull, Sun, Intel, Mellanox and ParTec. It consists of 2208 computing nodes with a total computing capacity of 207 teraflop/s. JUROPA’s operating system was developed by Forschungszentrum Jülich and ParTec. JUROPA is financed by Forschungszentrum Jülich within the framework of funding by the Helmholtz Association.
