Lochness¶
This very heterogeneous cluster is a mix of manufacturers, components, and capacities as it was built up in incremental purchases spanning several years.
Lochness was decommissioned on March 2024. Much of lochness nodes will be incorporated into Wulver cluster 2Q 2024.

- All nodes have:
- Ethernet network interface (1GigE or 10GigE)
- Infiniband network interface (mix of HDR100, EDR, and FDR speeds)
- 1TB local storage (mostly SSD but a few HD)
- All nodes have network accessible storage:
/home/: 26 TB/research/: 97 TB/afs/cad/: 50 TB
The cluster also features
- "CentOS Linux 7 (Core)" operating system
- Virtualized login and control nodes
- SLURM job scheduler
- Warewulf stateless node provisioning
- Managed entirely by NJIT personnel
Roughly half under warranty; rest are time and materials
