  • Compute time on gen1 nodes is charged at 40% of actual walltime. Depending on cores used and memory throughput demanded, these nodes may actually be about on par with gen2 (low memory throughput) or up to about 2–3 times slower.

Storage

  • Lustre parallel file system for /home and /sandbox
  • 42 TB effective (84 TB raw RAID-10)
  • local disk per compute node, 160–250 GB

Interconnect

  • Infiniband 4x DDR (Mellanox, onboard ) – MPI and Lustre
  • Ethernet 1 GB/s – node access and management

Power

  • Power consumption at typical load: ≈125 kW
