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, della, 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 node called https://mydella.princeton.edu for accessing the cluster through a web browser. This provides for easy file transfers and a way to allocate jobs for interactive use, mainly for Rstudio and Jupyter.
Please remember that these are shared resources for all users.
Della will be down for maintenance the second Tuesday of the month from 6-10 AM.
