The LCRC operated Fusion, a 30 teraflop computing cluster from 2010 to early 2017. Fusion featured 320 publicly usable compute nodes with Nehalem 2.6 GHz Xeon processors and a Mellanox QDR InfiniBand fat tree network. Overall, Fusion was comprised of 360 compute nodes of varying architectures including private condo nodes. In its last few years of operation, Fusion was used for overflow from Blues and for industry partnership projects. Fusion was retired on January 31, 2017.
Quick Facts
- 320 public compute nodes
- 36 GB of memory on each node
