For example, using SSH to connect to the Caviness login node with account ''traine'', type: | You need a [[abstract:caviness:account:account|Caviness account]] to access the login node and it is very important to review the information about [[abstract:caviness:account:account#cluster-accounts|cluster accounts]] and [[abstract:caviness:account:account#cluster-groups|cluster groups]] before connecting. For example, using SSH to connect to the Caviness login node with account ''traine'', type: |
| |
| <code bash> | <code bash> |
| ssh traine@caviness.hpc.udel.edu | ssh traine@caviness.hpc.udel.edu |
| | </code> |
| | or if you need you use X-Windows requiring X11 forwarding, then use |
| | <code bash> |
| | ssh -Y traine@caviness.hpc.udel.edu |
| </code> | </code> |
| |
| Please refer to Windows and Mac/Linux related sections for specific details: | You may set up direct SSH key authentication on Caviness once you are on the system by adding the desired public key to your authorized_keys file in the .ssh directory inside your home directory. Once you have a SSH key set up this way, you can access Caviness directly by running ''ssh caviness.hpc.udel.edu'' or ''ssh -Y caviness.hpc.udel.edu''. |

| | Once you are logged into Caviness, your account is configured as a member of an investing-entity group name ([[abstract:caviness:app_dev:compute_env#using-workgroup-and-directories|workgroup]]) which determines access to your group's compute nodes, queues and storage resources on Caviness. Setting your workgroup environment is required in order to submit jobs to the Caviness cluster. For example, the ''traine'' account is a member of the ''it_css'' workgroup. To start a shell in the ''it_css'' workgroup, type: |
