Della is a 4 rack Intel 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 both parallel and serial production jobs. The system has grown over time and includes groups of nodes using different generations of Intel processor technology. For hardware details, see the Hardware Configuration information below. All nodes are connected via FDR Infiniband high bandwidth low latency network.
System Configuration and Usage
The head node, della5, should be used for interactive work only, such as compiling programs, and submitting jobs as described below. No jobs should be run on the head node, other than brief tests that last no more than a few minutes. Where practical, we ask that you entirely fill the nodes so that CPU core fragmentation is minimized.
There is also a web portal at https://mydella.princeton.edu which provides access to the cluster through a web browser. This enables easy file transfers and interactive jobs: RStudio, Jupyter, Stata and MATLAB. A VPN is required to access the web portal from off-campus.
Della will be down for maintenance the second Tuesday of the month from 6-10 AM.
