Della is a 128-node Intel Westmere 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. Each processor has at least 4 GB of RAM allowing for large per task memory requirements. Half (64) of the nodes have 8 GB of RAM per processor. All are connected via a QDR Infiniband high bandwidth low latency network allowing for developing, testing, scaling and benchmarking codes in this environment.
In January 2014, 64 nodes of Ivybridge were added with 20 cores and 128G of memory per node.
Della will be down for maintenance the second Tuesday of the month from 6-10 AM.
