Dictiionary Attack - how-to-question

[Grazze]

there are 2 built-in GPU´s -

* Device #1: Intel(R) Core(TM) i5-4260U CPU @ 1.40GHz, skipped

* Device #2: HD Graphics 5000, 1472/1536 MB (384 MB allocatable), 40MCU

so I chose -d 2 because -d 1 is skipped, maybe I am wrong -

you mean I skip -d 2 then both GPU´s will be running ?

concerning -a 0, I learned that I have to specify an attack mode and -a 0 is a dictionary attack -

you mean if I skip -a 0 then password.txt will be used as dictionary attack ?
