Part of the cluster is accessible through PRACE as Tier-1 machine. The following description refers to this part.

Cluster hardware components:

  • access node,
  • service nodes,
  • 404 computational nodes (wn329 - wn732),
  • computational network - Infiniband DDR fat-tree full-cbb,
  • management network - gigabit ethernet.

Computational resources:

  • 4848 CPU cores,
  • >9,5 TB RAM (2GB/core),
  • ~247 TB storage (40 TB NFS + 207 TB Lustre),
  • node to node communication: throughput 20 Gbps, latency < 5 us.
