WPA/WPA2 PMK mode (2501)

[Kangaroot]

Maybe you're doing something wrong:

$ time wlangenpmkocl -e networkname -i rockyou -A pmklist
using: GeForce GTX 1080 Ti
9612471 plainmasterkeys generated, 4734589 password(s) skipped

real 0m45,772s
user 0m38,581s
sys 0m7,137s

Remarks:
skipped passwords are < 8 or > 63 chars

Main purpose for me is to verify allready retrieved PSKs on new incomming caps.
(in an extreme fast way, using nonce-error-corrections=128 in combination with hashcat's --remove to cleanup my database).
For that purpose I calculated a PMK list from hashcat's -m 2500 potfile.

I have two GPUs. Does this mean it uses only single unit?

Also, can you give example on how hashcat command will with -m 2501 will look like, please?
