force to use gpu only

[hashcloud]

hi guys,

i just setup my cracking machine right now with only one 7970, i have two more just haven't put them in yet.

Code:

lunar@lunar:~/hashcat$ amdconfig --adapter=all --odgt

Adapter 0 - AMD Radeon HD 7900 Series

When I run a test, it keeps attempting to use my CPU instead:

ERROR: ./kernels/4098/m0000_a0.VLIW1.llvmir: No such file or directory

Why is this? How can I make it use the GPU's only?

I believe I set everything up correctly (followed instructions here http://hashcat.net/wiki/doku.php?id=linux_server_howto)

[radix]

plus only uses GPU. verify that kernels, 4098, and the llvmir files all exist in the directory

[hashcloud]

Thanks radix, didn't even notice but 7zip extracted the files weird and there was no files in /kernels

[radix]

thats your problem then

[hashcloud]

Yes I know, I was just letting you know that I have solved it by extracting it again and the files were indeed in kernels/
