Fidelity on compute cluster with Slurm scheduler

nopech

Hello everyone

What is the recommended way to use Fidelity on a compute cluster using the Slurm scheduler?

Let's say I automated a CFD workflow using the python interface. The script is usually executed like this

fidelity2023.1 -batch -noFork -print -script script_full_path/script.py

and the number of processors is specified in the script like this

my_sim.start_simulation(num_proc=8)
Can I run fidelity as mpi application, e.g.
mpiexec -n 8 fidelity2023.1 -batch -noFork -print -script script_full_path/script.py
and what do I need to specify the num_proc within the script?
Thank you

    Fidelity has integrated the support for job schedulers like Slurm Workload Manager. All the required documentation are given on support.cadence.com

    Thank you, I was hoping there is a way to treat fidelity as an mpi application so it would fit standard workflows.

    The Fidelity installation note has a section "Set up Fidelity on a cluster for HPC" in which examples are provided also for "Set up a cluster in a generic way". At the end of that section an example is provided using the Open MPI library.
