Della is a 192-node Intel Westmere/Ivybridge computer cluster, originally acquired through a joint effort of Astrophysics, the Lewis-Sigler Institute for Integrative Genomics, PICSciE and OIT. It is intended as a platform for running production parallel jobs. Sixty-four of the Westmere nodes have 4 GB of RAM per core; sixty-four more Westmere nodes have 8 GB of RAM per core, allowing for large per task memory requirements; and 64 20-core Ivybridge nodes have 6.4 GB of RAM per core. All are connected via a QDR Infiniband high bandwidth low latency network allowing for developing, testing, scaling and benchmarking codes in this environment.
Della will be down for maintenance the second Tuesday of the month from 6-10 AM.
