Primary Usage Notes

Access Host (Login)

Login is the node use to access ExCL and to proxy into and out of the worker nodes. It is not to be used for computation but for accessing the compute notes. The login node does have ThinLinc installed and can also be used for graphical access and more performance x11 forwarding from an internal node. See ThinLinc Quickstart.

Host	Base Resources	Specialized Resources	Notes
login	4 core 16 Gi vm	-	login node - not for computation, TL

General Interactive Login Use

These nodes can be access with ssh, and are availible for general interactive use.

Notes:

• All of the general compute resources have hyperthreading enabled unless otherwise stated.. This can be changed on a per request basis.

• TL: Thinlinc enabled. Need to use login as a jump host for resources other than login. See ThinLinc Quickstart
• Slurm: Node is added to a slurm partition and will likely be used for running slurm jobs. Try to make sure your interactive use does not conflict with any active Slurm jobs.

  • Most of the general compute resources are Slurm-enabled, to allow queuing of larger-scale workloads. [e-mail] for specialized assistance. Only the systems that are heavily used for running Slurm jobs are marked “Slurm” above.

• docker — for docker runner jobs.

• devdoc — for internal development documentation building and hosting.

Note: any node can be used as a CI runner on request. See GitLab Runner Quickstart and GitHub Runner Quickstart. The above systems have a dedicated or specilized use with CI.

Docker

• docker — Node with docker installed.
