==== Logging on the cluster ==== | |
To initiate an SSH connection from a Mac/UNIX/Linux system to the cluster's login (head) node, use | |
the generic command | |
| |
''ssh''<<//options//>> <<//HPC_username//>>@<<//HPC_hostname//>> | ===== Logging on to Farber ===== |
| You need a [[abstract:farber:account:account|Farber account]] to access the login node. For example, using SSH to connect to the Farber login node with account ''traine'', type: |
| |
For example, | |
<code bash> | <code bash> |
ssh -Y traine@mills.hpc.udel.edu | ssh traine@farber.hpc.udel.edu |
</code> | </code> |
| |
This **ssh** command is on your local system. This example assumes you have a local command line interface, and have an X11 server running, for example, Mac/UNIX/Linux or cygwin/X (with the openssh client) | Please refer to Windows, Linux & Mac related sections for specific details - |

<note tip>**Windows with PuTTY/Xming**: When using the recommended [[http://udeploy.udel.edu/software/putty-with-xming|PuTTY/Xming on Windows]] installation instructions, you create a saved session with the options to want to use every time you logon. You can create as many saved sessions as needed with various options. | ===== Using Farber ===== |

<note tip>**Mac/UNIX/Lunix with command line SSH**: | Your account is configured as a member of an investing-entity group name (workgroup) which determines access to your group's compute nodes, queues and storage resources on Farber. Setting your workgroup environment is required in order to submit jobs to the Farber cluster. For example, the ''traine'' account is a member of the ''it_css'' workgroup. To start a shell in the ''it_css'' workgroup, type: |
When using the recommended setup for [[general/connect/ssh-command-line|command line SSH]], you can add a service that bundles options you want to use every time you logon or copy files. You can add as many services as needed with various options. | |
</note> | |
| |
| <code bash> |
| workgroup -g it_css |
| </code> |
| |
| You will need to know [[:training:linux:linux|Unix/Linux]] and [[:training:hpc:hpc|HPC]] concepts before using Farber. Use the <html><span style="color:#ffffff;background-color:#2fa4e7;padding:3px 7px !important;border-radius:4px;">sidebar</span></html> to navigate documentation about Farber, from accessing the cluster to running applications, using [[:software:software|software]] and available [[:training:training|training]]. |
