Using SSH to connect to nodes

To SSH to the head node in a cluster, run:

$ adam ssh -n [cluster-name]

EXAMPLE: To SSH to the head node in a cluster named “cluster”:

$ adam ssh -n cluster

To connect to a specific node, include the node number after the cluster name. Node 0 is the head node, node 1 is the first compute node, and so on.

EXAMPLE: To SSH to the second compute node in a cluster named “cluster”:

$ adam ssh -n cluster 2
