Supernova - computing cluster installed at WCNS (Wroclaw Centre for Networking and Supercomputing, in polish: WCSS - Wrocławskie Centrum Sieciowo-Superkomputerowe). The cluster is a part of PRACE Tier-1 infrastructure and EGI grid infrastructure (via national PL-Grid initiative).
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.
