Scaling Scripts

This repo contains scripts to launch jobs for weak/strong scaling.

To launch a set of weak scaling jobs, you will generally modify the parameters in weak_params.sh as necessary, and then execute weak_scaling.sh which will queue a set of jobs on the system.

The executed jobs will generated JSON files which record timing information for the different execution stages. A equivalent user readable TXT file will also be generated which records a summary. This data is utilised by scaling_graphs.ipynb to generate graphs of the results.

timed_model.py

This is an underworld script which executes a simple model and records timing information. The model covers most of the fundamental underworld constructs, including solvers, vis and data IO.

weak_scaling.sh

This script will queue a set of jobs for testing underworld simulation weak scaling. It uses the settings in weak_params.py to determine run configuration.

weak_params.sh

This script contains run parameters for weak scaling tests. The user should generally only need to modify values here.

strong_scaling.sh

This script will queue a set of jobs for testing underworld simulation strong scaling. Note that this script is old and requires updating.

scaling_graphs.ipynb

This notebook utilises simulation results to generate scaling graphs.

magnus_container_go.sh

This script configures an environment and launches the required script on Magnus using containers.

magnus_baremetal_go.sh

This script configures an environment and launches the required script on Magnus running directly on machine.

gadi_baremetal_go.sh

This script configures an environment and launches the required script on Gadi running directly on machine.
