OpenCL kernel self-test failed and slower than benchmark - timezy - 09-03-2019
My GPU and CPU usually work fine with hashcat but when I use some attack modes with my Intel CPU, there is an error
ATTENTION! OpenCL kernel self-test failed
I followed the instruction for the wrong driver but it hasn't solved the error. How do I solve the error?
When I use the same attack modes with just my GPU, the benchmark is 10 times higher than the actual performance. Is that because the CPU isn't being used because of the error?
RE: OpenCL kernel self-test failed and slower than benchmark - philsmd - 09-03-2019
which hash mode and which version of hashcat and driver ?
what hardware do you have (CPU and GPU) ?
please also try this hashcat version: https://hashcat.net/beta
RE: OpenCL kernel self-test failed and slower than benchmark - timezy - 09-03-2019
The hashcat beta version solved the CPU error but for the GPU:
CUDA SDK Toolkit installation NOT detected
CUDA SDK Toolkit installation required for proper device support and utilization
Falling back to OpenCL Runtime
Will installing CUDA SDK Toolkit get me a better GPU benchmark? Will it make a difference?
