Since BitCrack already utlize GPU, do you think it's possible to achieve higher hashrate (with same device) by modifying his software?

I guess so because His program can utilise Multiple GPUs where as bitcrack can only use 1 at a time. And for the guy posing the WIFsolver CUDA does it work with multiple GPUs. I have 8 Tesla V100s on a 2x Xeon 256 GB ram server. Let me know if we wanna try out something before this Sunday. As i am flying out to a remote place for work and won't be available for 2 weeks unless there is network here and there sometimes.
