OK, that makes more sense.

Chilean, I believe you are wrong.

The only reason GPUs can't be used with Rosetta is that nobody yet took the effort to write the code. GPUs have sufficient instruction set, faster RAM, and greater computing power than CPUs. Complaints about their single precision architecture are misplaced, as doubles can be processed on any CUDA capable GPU, only it takes more cycles. The "classroom" and "off-road" analogies are too empiric, CPU is not smart, it only does what you tell it to. There is no fixed connection between the complexity of Rosetta and x86/x64 architecture - any task can be programmed to run on any kind of processor if there is enough memory and time.

This was happening repeatedly. Finally I aborted the task.
