research infrastructure for the development of membrane systems, covering the entire spectrum of services from the production of the materials needed and the characterization using analytical instruments right up to the testing of modules and components. A priority is the development of novel membrane systems for energy technology in order to separate greenhouse gases from exhaust gases and to provide a basis for novel fuel cells and solid-state batteries. Other research projects Forschungszentrum Jülich has a lattice steel mast (124 metres high) for meteorological measurements. It is equipped with platforms at 10 m, 20 m, 30 m, 50 m, 80 m, 100 m, and 120 m, on which measuring instruments are positioned. The measuring mast was erected in 1963/4 and is a triangular steel framework construction. Former research activities Early supercomputers IBM p690 cluster “Jump” (2004) The massively parallel supercomputer IBM p690 cluster Jump was put into operation at the beginning of 2004. With 1,312 Power4+ 2C 1.7 GHz processors (41 nodes, each with 32 processors) and an internal memory of 5 terabytes (128 gigabytes per node), the computer had a maximum performance of 5.6 teraflop/s. It was ranked 30th in the list of the world’s most powerful computers at the time of its inauguration. The nodes were connected to each other by a high performance switch (HPS). Through a globally parallel data system, applications had access to more than 60 terabytes of storage space and an integrated tape drive with a capacity of one petabyte. The IBM p690 cluster Jump was run on the operating system AIX 5.1. In 2008, the system was temporarily replaced by IBM Power6 p6 575 until JuRoPA began operating. Jülich BlueGene/L supercomputer (JUBL, 2006) JUBL was unveiled in 2006 and is considered to be JUGENE’s predecessor. It was decommissioned following JUGENE’s successful installation in mid-2008. Jülich BlueGene/P supercomputer (JUGENE, 2008) On 22 February 2008, the massively parallel supercomputer JUGENE, which was based on IBM’s BlueGene/P architecture, went into operation. At times, it was the fastest computer in Europe and the fastest civil computer in the world. In 2012, it was replaced by JUQUEEN. HPC-FF and JuRoPA (2009) On 26 May 2009, the two computers HPC-FF and JuRoPA went into operation. The two computers could be connected for specific tasks and together they achieved a performance of 274.8 teraflop/s with Linpack, which placed them tenth worldwide. The operating system was SUSE Linux Enterprise Server. This
