TMUX
Persistent terminal sessions on login nodes.
Template placeholder
Replace this page with site-specific content. The URL and sidebar placement intentionally match the Wistar HPC documentation structure.
Overview
Use this section for the short version: what the user needs to know, when to use it, and any policy boundaries. Keep it boring and clear; future-you will thank present-you.
Common tasks
- Task 1: describe the normal path.
- Task 2: include exact commands where appropriate.
- Task 3: point users to support before they invent a workaround with impressive blast radius.
Example
# Replace with a real cluster-safe example
sinfo
squeue -u "$USER"
Troubleshooting
| Symptom | Likely cause | What to check |
|---|---|---|
| Job stays pending | Requested resources unavailable | squeue -j <jobid> -o '%i %T %R' |
| Login feels slow | Heavy process on login node | Move work into a scheduled job |
| Module not found | Module tree or environment issue | module avail and support docs |
