CST Studio Suite 2026 - HPC Job Submission Frontend Modifications for 2FA

This project provides modified versions of the Python and Qt-based frontend components used by CST Studio Suite 2026 to submit simulation jobs to an HPC cluster over SSH, adding support for TOTP and Okta-based two‑factor authentication.

The repository includes the following modified files:

• hpc_job_submission_gui.py
• hpc_submit.py

These files replace the originals located in:

• C:\Program Files\CST Studio Suite 2026\Library\Python\lib\emag_job_submission_gui\

Modifications include:

• Okta 2FA push notification support.
• TOTP 2FA support including for DUO.
• Improved submission error handling.
• Added walltime option (Auto or HH:MM).
• Added memory option (Auto or explicit values like 16GB, 64GB, etc.).
• Enhanced GPU selection logic with remote queue limit awareness.
• Integration with remote queue limits:
  • Automatically query and set the maximum GPU count allowed for the selected queue.
  • Query and prefill available walltime when supported by the scheduler.

Configuration Notes

• Memory option accepts Auto or numeric values with optional units (M/MB, G/GB, T/TB). Values are converted to MB before submission.
• Walltime option accepts Auto or HH:MM.
• Remote queue limit queries refine available GPU and walltime options when the scheduler provides this information.

Increasing Debugging output

Environment variable HPC_SUBMIT_DEBUG can be set to 1 to increase debugging.

How to set it in Windows PowerShell before starting submission GUI:

$env:HPC_SUBMIT_DEBUG = "1"

& "C:\Program Files\CST Studio Suite 2026\AMD64\python\python.bat" -E -m emag_job_submission_gui.hpc_job_submission_gui

How to set it in Command Prompt before starting submission GUI:

set HPC_SUBMIT_DEBUG=1

"C:\Program Files\CST Studio Suite 2026\AMD64\python\python.bat" -E -m emag_job_submission_gui.hpc_job_submission_gui
