Scalable prediction-adjacent testing application. The drivers in this driver suite are intended to exercise all of the features used in the MIRGE-Com prediction runs at CEESD.
Combozzle (combozzle.py) is a production-adjacent performance testing driver
that is constructed by using a simple box mesh generator in place of
the production driver (isolator.py) gmsh-based grid generator. The combozzle
driver, like the production drivers, requires the production branch of
MIRGE-Com in order to run.
The combozzle.py driver is the main driver. The features and
(optional) features are roughly as follows:
- MPI: 1 rank (n ranks)
- DT: fixed (fixed cfl)
- Timestepping: Euler (rk4, rk54)
- RHS: Navier-Stokes (Euler, dummy)
- EOS: Mixture (nspecies inert, single gas)
- Shock cap: Laplacian AV (off)
- Additional: Sponge (off)
All features used by MIRGE-Com in the CEESD prediction runs
are ON by default. The many parameters for the configuration
of features and run details can be found near the top of the
main function in combozzle.py. The code can also read config
parameters from YAML files.
Most of the subdirectories contain experiments set up to run on Lassen@LLC.
The bsub scripts are designed to be submitted with bsub <script> on Lassen.
Further descriptions for each experiment should be found in README in the
experiment-specific directories.
