About Ganesha Cluster

The primary, general purpose compute cluster at C2B2 is now called "Ganesha.", This HPC cluster s a Linux-based (Rocky9.4) compute cluster consisting of 62 Dell Server 2 head nodes and a virtualized pool of login (submit) nodes 8 Weka nodes. The nodes fit in a dense configuration in 9 high-density racks and are cooled by dedicated rack refrigeration systems.

Getting Access

In order to get access to this HPC cluster, every research group needs to establish a PI Account using an MoU-SLA agreement that can be downloaded DSBIT-MOU-SLA.pdf This document provides further details about modalities, rights & responsibilities, and charges etc.

Logging In

You will need to use SSH in order to access the cluster.  Windows users can use PuTTY or Cygwin or Mobax. MacOS users can use the built-in Terminal application.

Users log in to the cluster's login node at ganesha.c2b2.columbia.edu :

$ ssh <UNI>@ganesha.c2b2.columbia.edu

Interactive login to Compute Node

Upon initial login to Ganesha, you'll find yourself on a login node. These nodes are meant for basic tasks like editing files or creating new directories, but not for heavy workloads. To perform more complex tasks, it's essential to transition from the login node to an interactive session on a compute node.
