force to use gpu only - hashcloud - 04-21-2013
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.

ERROR: ./kernels/4098/m0000_a0.VLIW1.llvmir: No such file or directoryWhy 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)
RE: force to use gpu only - radix - 04-21-2013
plus only uses GPU. verify that kernels, 4098, and the llvmir files all exist in the directory
RE: force to use gpu only - hashcloud - 04-21-2013
Thanks radix, didn't even notice but 7zip extracted the files weird and there was no files in /kernels
RE: force to use gpu only - radix - 04-21-2013
thats your problem then
RE: force to use gpu only - hashcloud - 04-21-2013
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/
