Green Computing: Resource use minimisation through automation and optimisation

The school was run as three days of content. The first day was an introduction to ADACS and Australian computing resources, followed by a panel discussion on the topic of “The imperative to reduce carbon emissions in astronomy”. The second two days consisted of four sets of 90-minute workshops. The school was held online via Zoom.

Topics covered include:

• High level optimisation
• Workflows
• Profiling
• Workflow optimisation
• (SLURM) job packing
• Containers
• Parallelism (basic and advanced)

Workshops

1. Introduction, high level optimisation, workflows, and profiling
2. Activity: Simple profiling in bash and python
