    • 2 NVIDIA V100 GPU cards (owned by a researcher).
    • 18 NVIDIA A100 GPU cards (6 owned by OSCER, 12 owned by researchers).
    • 22 A100 GPU cards have been ordered (8 owned by OSCER, 14 owned by researchers), for a total of 40 A100 GPU cards (14 owned by OSCER, 26 owned by researchers)
  • Large Memory Nodes
    • PowerEdge R930
    • 1 × quad Haswell E7-4809v3 8-core 2.0 GHz, 1 TB RAM (OSCER)
  • Storage
    • High performance parallel filesystem, global user-accessible: DataDirect Networks Exascaler SFX7700X, 70 SATA 6 TB disk drives, ~309 TB useable
    • Lower performance servers full of disk drives, global user-accessibe: ~150 TB useable
  • Networks
    • Infiniband: Mellanox FDR10 40 Gbps, 3:1 oversubscribed (13.33 Gbps)
      NOTE: 76 compute nodes don’t have Infiniband, at the owner’s discretion.
    • Ethernet: Gigabit Ethernet (GigE) to each compute node, uplinked to a top-of-rack GigE switch, and each GigE switch uplinked at 2 × 10 Gbps Ethernet (10GE) to a pair of 10GE core switches.
  • Operating system
    • CentOS 8
    • Batch scheduler is SLURM
    • Compiler families include Intel, Portland Group (now part of NVIDIA) and GNU, as well as the NAG Fortran compiler.
  • Schooner is connected to Internet2 and to Internet2’s 100 Gbps national research backbone (Advanced Layer 2 Services)
