I am using a Windows 10 computer with an NVidia graphics card.
I notice when I run my hashcat.exe and go to the task manager, the GPU is at 0% for the hashcat.exe in the task manager.
When I run "./hashcat.exe -I", I get:
Based on the information above, I would want to run -D 2 since the type is GPU. The command I use to run it all is
And once it runs, I get:
In the above code, the key part I'm curious about is why device 2 is being skipping and running device 1 when I specified -D 2?
I am new to hashcat so it all is a bit unfamiliar right now but I do appreciate any support anyone can give. Thank you for your time and reading my post.
