Summary of Issue

During a tomography course, a display node ([NODE_ID: display002]) on the CSSB-specific Maxwell cluster appears to have crashed due to overloading. The user requests verification of the node’s status.

Suggested Solution

  1. Check Node Status:
  2. Administrators should verify if [NODE_ID: display002] is operational or requires a restart.

  3. Monitor resource usage (CPU/GPU/RAM) to confirm overloading as the cause.

  4. Preventive Measures for Future Courses:

  5. Load Balancing: Direct users to less crowded display nodes (e.g., max-cssb-display.desy.de for CSSB members).
  6. Session Limits: Enforce session limits or resource quotas during high-usage events.

  7. Browser-Based FastX: Recommend browser sessions (e.g., https://max-cssb-display.desy.de:3389/) for better GPU acceleration and persistence.

  8. User Guidance:

  9. Advise participants to close unused applications to reduce load.
  10. Suggest using dedicated display nodes (e.g., max-cssb-display) instead of shared nodes like max-display.
