- all nodes are dual-socket (8 cores/node).
- gen1 nodes are charged at 50% discount of walltime. Depending on cores used and memory throughput demanded, they may be about on par with gen2 (low memory throughput) or up to about 2–3 times slower.
Infrastructure nodes
- 2 Management nodes
- 2 Lustre MDS
- 4 Lustre OSS
- dual socket, quad core (Intel Xeon E5345, 2.33 GHz)
- pairwise failover
Storage
- Lustre parallel file system
- 42 TB effective (84 TB raw RAID-10)
- 2 NexSAN SATAbeast
- 160–250 GB local disk per compute node
- NFS
- for user applications and cluster management
- highly-available server based on DRBD
Interconnect
- Infiniband 4x DDR (Mellanox, onboard ) – MPI and Lustre
- Ethernet 1 GB/s – node access and management
- Ethernet 10 Gb/s – crosslinks and uplink
- FibreChannel – storage backends
Power
- UPS (2) – carries infrastructure nodes and network switches
- PDUs – switched and metered
- Power consumption at typical load: 118 kW
