How Are Jobs Run for DesignSafe on TACC? – Big Picture

TACC (Texas Advanced Computing Center) provides the high-performance computing (HPC) resources that DesignSafe uses to run jobs. Specifically, jobs submitted from DesignSafe are executed on TACC’s systems — typically Stampede3 or similar clusters.

Step-by-step Process:

  1. Log into DesignSafe

    • You access it through https://www.designsafe-ci.org

    • You don’t need to interact with TACC directly unless you want to.

  2. Use the Workspace

    • DesignSafe has an interactive workspace:

      • Jupyter Notebooks

      • MATLAB

      • SimCenter tools

      • Other scientific apps like OpenSees, ADCIRC, etc.

    • These are all powered on the backend by TACC resources.

  3. Submit Job

    When you submit a job via DesignSafe:

    • The job is packaged with:

      • Your script

      • Input data

      • Parameters (like CPU cores, memory, wall time)

    • DesignSafe translates this into a SLURM job (TACC uses SLURM as its job scheduler).

    • The job is then sent to a TACC queue (often the designsafe or community queue on Stampede3).

  4. Execution on TACC

    • TACC runs the job exactly like any HPC job using SLURM.

    • The job runs on actual compute nodes (on Stampede3, for example).

    • Output files are saved in your DesignSafe project or data workspace.

  5. Results

    • Once complete, results are sent back to DesignSafe automatically.

    • You can view, download, or analyze the data directly in the platform.

DesignSafe Apps do all this automatically!#

  • Sets up SLURM job scripts for you

  • Submits jobs via APIs to TACC’s scheduling system

  • Manages your allocation (so you don’t have to use TACC’s sbatch, squeue, etc.) You can access the APIs (Tapis) directly from your Python script.

or you can manage intermediate steps yourself.
