Description
In certain cases, users can hit the node process limit if they are running multiple jobs on the same node.
This can lead to odd behaviour like jobs that run infinitely long because they fail to spawn new processes.
Reported user case:
- 15 simultaneous jobs on the same node.
- Causing major jobs slowdowns (poor GPU utilization, etc...)
- Notes that this is not reproducible, sometimes it works, sometimes it fails.
- Setting
ulimit -u 8192helps fix the issue.

Research direction
Start by locating the documentation for running multiple jobs on one node and for process or resource limits. Record the reported 15-job scenario, intermittent process-spawn failures, impact on GPU utilization, and the ulimit -u 8192 workaround. Done means the symptoms, limits, and workaround are documented in the appropriate place.
