Edda

Edda is an IBM OpenPOWER 720 cluster running SuSE SLES 9 Linux. VPAC estimate Edda's performance to be benchmarked at around 1 Teraflop.

Specifications

  • 190 1.67GHz Power5 CPUs
  • 47 4 way Compute nodes, 1 2 way compute node
  • 24 nodes with 16G ram
  • 24 nodes with 8G ram
  • SLES 9 linux from SUSE

Compilers

Edda is a SUSE Linux operated system. Linux users will find the familar GCC C and Fortran compilers present. In addition to these compilers, IBM's own high performance C, C++ and Fortran compilers are also available, which the default MPI installation will use.

NB: Please be aware that both the IBM and GCC compilers will emit 32-bit code by default, rather than 64-bit. To emit 64-bit code please use -m64 for GCC and -q 64 for the IBM compilers.

Cores: 190
Nodes: 48
