Artemis is made up of a number of components, including the login nodes, compute nodes, storage system, and management nodes. The compute nodes, Lustre storage and management nodes are all connected by a high performance, low-latency “interconnect” based on Mellanox InfiniBand (IB) , which is a proprietary networking infrastructureinterconnect. There is also a 10 Gbps Ethernet management network interconnecting the compute, login and management nodes for compute node and batch job management.
Artemis has 56 “Standard” Haswell compute nodes and 80 “Standard” Broadwell compute nodes based on dual socket servers.
The key features of the Haswell nodes are:

CPU model | Intel Xeon E5-2680 V3 @ 2.50 GHz |
CPU generation | Haswell |
Number of cores per node | 24 (2 x 12) |
Resident RAM | 128 GB (8 x 16 GB) DDR3 DIMMs |
Disk storage | 2 x 1 TB 7k NL-SAS in RAID 1 |
Number of 10 Gbps interfaces | 2 |
Number of 1 Gbps interfaces | 2 |
InfiniBand interface | FDR InfiniBand |
The key features of the Broadwell nodes are:
Attribute | Value |
|---|---|
