CST Studio Suite

CST Studio Suite Status

CST Studio 2022_ is the current version of the CST Studio Suite installed on the HPC. Currently, Single-Node Module and GPU acceleration are tested and confirmed to be working via a manual CLI call.

The cst_ job-submission scripts will work, however they do not allocate resources in an effective manner for DeepThought. Use at your own risk, as a manually created SLURM job will give you much better results.

Below are the modes of operation and their status.

Run Mode	Status
GPU Accelerated	Working/Released
Single-Node Parallel	Working/Released
Multi-Node Parallel	Testing/Unreleased

CST Studio Suite Quickstart Command Line Guide

To run a CST Studio job on the HPC you will need your .cst file, and the associated SLURM script. Modify any to your requirements.

Single-Node, GPU Accelerated

cst_design_environment -defaultacc -with-gpu=<NUMBER_OF_GPUS_REQUESTED> -m -r -num-threads=$SLURM_CPUS_PER_TASK -project-file /path/to/projet.cst
Single-Node, CPU Only

cst_design_environment -m -r -num-threads=$SLURM_CPUS_PER_TASK -project-file /path/to/project.cst
Multi-Node GPU Accelerated

Coming Soon, when MPI is released
Multi-Node, CPU Only
