you dont have GPU ? any GPU ?
This code is only for CPU, working with two Threads...
Sure, I use GPU too, but I don't can coding for Cuda applications like, vanitygen, Kangaroo, etc...
i will sugggest same working your code at c and gpu, above link use git scripts, working 10005 better then you python code , ttoal same function,
even if your cpu have gpu inside, like i3-6100 process have gpu, its also work on this rotar, and auto use gpu at cpu based command,
https://github.com/phrutis/Rotor-Cuda, for fully random at gpu like bitcrack is BitCrack2, use that, you will forget python
dont forget merit me....
