Some people uses Raspberry Pis or an old desktop computers to make a cluster.
Either You trade power for watts or you trade watts for power.
I came across Asahi Linux. I think it opens possibilities to have 600$ powerful computers running on m1 using very low power. Using it as a single instance or a cluster.
What do you think ? What is your feeling about it ? :)
Would be interested to see how the power draw is, from my experience on macbook the battery life was taking a ~30% hit on Asahi compared to MacOS. Whatever optimization Apple does just isn’t there. Also would virtualization work? Be efficient? Doubt you could get Proxmox running on one without a lot of hacking.
