Supercomputers at GCS

The Gauss Centre can boast of a state-of-the-art high-performance computing and networking infrastructure:
  • the JSC can provide its 1 PetaFlop/s IBM Blue Gene/P JUGENE and the 207 TeraFlop/s cluster JUROPA,
  • the LRZ recently expanded its SGI Altix 4700 system to 62.3 TeraFlop/s, and
  • the HLRS offers its 12 TeraFlop/s NEC SX/8.
The architectures of these machines are different yet complementary. Each one favours special types of applications. The Altix can be used as a shared-memory machine, the SX8 is highly efficient for vectorised codes, the Blue Gene is adequate for applications which scale to extreme processor numbers, and the cluster JUROPA provides large-memory SMP nodes.
