Detailed System Configuration

The following provides some additional detail about the system configuration:

  • 96 nodes in 24 system boards, each containing:
    • One 16-core 1.848GHz Fujitsu SPARC64 IXfx cpu
      • L1 cache (on chip): 32KB/core (I) + 32KB/core (D)
      • L2 cache (on chip): 12MB per 16-core cpu
  • 32 Gbytes DDR3-1333 memory
  • Total of 3TB of RAM on compute nodes
  • 4 dual socket, 6-core Fujitsu RX200 S7 servers for FEFS file service
  • Approximately 122 TBytes of usable global storage using 4 disk trays, each with 10/12 x 3TB SAS drives
  • One Mellanox Infiniband switch with 36 FDR IB ports for both MPI and FEFS filesystem traffic
