I’ll iterate towards a good solution. This was a somewhat realistic but naive solution (I have customers doing largely what I’ve described in the article).

If I could find a way to encourage people to run their work in a power efficient way using economies of scale from this series, I would be terribly happy.

Interestingly I suspect public-cloud FaaS solutions (e.g. AWS Lambda) will achieve highest utilisation rates due to high rate of CPU sharing - but I’m a long way off from showing that with data.
