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 Sensor 0: Temperature - 33.00 C

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

Code:

lunar@lunar:~/hashcat$ ./oclHashcat-plus64.bin -m 0 md5.hash.txt oclHashcat-plus v0.14 by atom starting... Hashes: 3 total, 1 unique salts, 3 unique digests Bitmaps: 8 bits, 256 entries, 0x000000ff mask, 1024 bytes Rules: 1 Workload: 256 loops, 80 accel Watchdog: Temperature abort trigger set to 90c Watchdog: Temperature retain trigger set to 80c Device #1: Tahiti, 2048MB, 925Mhz, 32MCU Device #1: Kernel ./kernels/4098/m0000_a0.Tahiti_1084.4_1084.4 (VM).kernel not found in cache! Building may take a while... 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

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/
