[everforward]

I think it's more of a business strategy issue than a technical one.

I suspect it would be trivial for Vast or GPUDeploy to spin up a benchmarking job before allowing sales on that machine. I'm not an expert on PCIe lanes, but I would think the performance issues would be visible via bandwidth or latency on the lanes.

It kind of makes sense to me, though. If I were looking for absolute reliability and was willing to pay for it, I'd just go to one of the many GPU cloud vendors. Likewise, I suspect anyone willing to really work on getting good performance would rather be a real provider or sub-provider than being part of this nebulous C2C GPU cloud.
