| ==== Logging on the cluster ==== | ===== Logging on to Mills ===== |
| To initiate an SSH connection from a Mac/UNIX/Linux system to the cluster's login (head) node, use | You need a [[abstract:mills:account:account|mills account]] to access the login node. For example, using SSH to connect to the Mills login node with account ''traine'', type: |
| the generic command | |
| |
| ''ssh''<<//options//>> <<//HPC_username//>>@<<//HPC_hostname//>> | |
| |
| For example, | |
| <code bash> | <code bash> |
| ssh -Y traine@mills.hpc.udel.edu | ssh traine@mills.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 and Mac/Linux 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. | |

| |
| <note tip>**Mac/UNIX/Lunix with command line SSH**: | Once you are logged into Mills, 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 Mills. Setting your workgroup environment is required in order to submit jobs to the Mills 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 Mills. Use the <html><span style="color:#ffffff;background-color:#2fa4e7;padding:3px 7px !important;border-radius:4px;">sidebar</span></html> to navigate documentation about Mills, from accessing the cluster to running applications, using [[:software:software|software]] and available [[:training:training|training]]. |
