These sorts of thing tend to parallelize well too. If it were written for CUDA or similar, I wouldn't be surprised to see it finish in a few hours.

This is not a straight brute-force attack. I don't know how well it parallelizes, but Marc is aware of the existence of GPUs. (Also, it takes a few weeks. No point in messing around with CUDA...)
