1592718 : Maxwell fuer FLUKA Simulationen

Here is the anonymized and summarized version of the query:

Summary of Request

A project coordinator ([ROLE]) needs temporary access to the Maxwell cluster for FLUKA-based shielding calculations as part of a test beam project. The requirements are: - Resources: ~100 CPU cores, 1 GB RAM per core. - Duration: 4 weeks. - Access: Maxwell cluster (including the all partition). - FLUKA Installation: - Initially suggested to install FLUKA in $HOME (for single-user testing). - Query whether a central FLUKA installation is available on Maxwell.

Suggested Solution/Next Steps

  1. Access to Maxwell:
  2. Confirm eligibility for temporary access (e.g., via DESY affiliation or collaboration agreement).
  3. Request access via the standard procedure (contact uco@desy.de with justification, including project details and duration).

  4. Specify the need for the all partition if high-core-count jobs are required.

  5. FLUKA on Maxwell:

  6. Central Installation: Maxwell already provides a centrally managed FLUKA installation (see context below). The user should:
    • Register on the FLUKA website and accept the single-user license.
    • Forward the confirmation email to uco@desy.de to be added to the fluka group.
    • Load the module via: bash module load maxwell fluka

  7. Local Installation: If the user prefers to test a custom setup, $HOME is a viable option, but the central installation is recommended for simplicity.

  8. Resource Allocation:

  9. For 100 cores, the user may need to submit jobs to the all partition (subject to availability and fair-use policies).

  10. Advise the user to test smaller-scale jobs first to validate the setup.

  11. Acknowledgment:

  12. Remind the user to acknowledge Maxwell in publications/presentations (see Maxwell documentation).
