I'd imagine you're asking like, how did they _physically_ do it? That is an interesting question, I'd love to see pictures.

But from an infrastructural standpoint I'd imagine that just putting a bespoke Linux distro on each of the phones and connecting them to the same network would enable the same kinds of orchestration you'd do in a "regular cloud."

Both actually. How did they do it physically and what did they run on the phones? I found it especially interesting that 20% of the devices had to act as master or networking nodes

I would guess that it would be an app that uses wireless networking.

Probably slow as molasses compared to a blade server but also probably pretty powerful since it has so many compute nodes.
