Gpu

A miner that schedules itself onto any GPU node is a workload like any other, and its economics come down to one subtraction. Drive the cost term to zero and the answer is always yes, which is the whole reason cryptojacking exists. A qualitative argument: the original never recorded the figures.

The goal was to make idle hardware pay the electricity bill. The route ran through IOMMU passthrough into a Windows VM, then out again into containers, and what survived the mining was the scheduling pattern underneath it. I never measured whether it paid.
