Della is a 240-node Intel Westmere/Ivybridge/Haswell/Broadwell 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. Forty eight 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 80 20-core Ivybridge nodes have 6.4 GB of RAM per core. The 32 Haswell 20 core nodes also have 6.4GB/core memory. The 16 Broadwell 28 core nodes have 4.6 GB/core. All are connected via a QDR or FDR 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.
