Gtx 860 m Problem

[br.]

The problem is already told to you in the output of your program
"ATTENTION!
The wordlist or mask you are using is too small.
Therefore, oclHashcat is unable to utilize the full parallelization power of your GPU(s).
The cracking speed will drop.
Workaround: https://hashcat.net/wiki/doku.php?id=fre...full_speed"

As you can see, your actual mask is only 4 digits long, for a total of 10x10x10x10=10000 combinations, while your GPU hashes at 33101/s, meaning that the entire process is over in less than a second.

The solution? Use a larger mask.

I'm sure you must've read through what you yourself posted, it gives you all the information you need to know.
