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.

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)
plus only uses GPU. verify that kernels, 4098, and the llvmir files all exist in the directory
Thanks radix, didn't even notice but 7zip extracted the files weird and there was no files in /kernels
thats your problem then
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/
