I’ve been having a look at some of the projects around that will support Aarch64 for voluntary Grid Computing. Off the back of the Raspberry Pi, BOINC has an Arm client and several projects I have previously contributed to have workloads suitable for running on the Arm build client.
Rosetta@Home is protein folding simulation for disease research. Lots of workloads to be done there.
One of the last things I did at Intel was turn some of their “spare” super compute clusters onto Folding@Home. They chewed through quite a bit of protein simulation time. It’s a shame Intel didn’t keep that kind of thing up after I left
We actually had a pair of Ampere eMag boxes on the Covid research team, if I remember correctly. Which reminds me, I should look for some de-commissioned eMags on eBay, wonder if there are any cheap ones floating around by now
