Hashcat do not recognize my CPU with OpenCL - clenet - 01-17-2024
Hi,
I installed hashcat 6.2.6 on my laptop (HP Probook 450 G9 with intel core i5-1235U)
I installed too Intel CPU Runtime for OpenCL applications version 24.0
But hashcat still do not recognize my CPU with option "-D 1,2"
The OpenCL driver for my GPU is recognized but I want to use GPU+CPU
Thanks for your feed back!

GPU+CPU is often not recommended except for extraordinarily slow hashes like some scrypt modes. CPUs are significantly slower than GPUs and often the GPUs just get starved of work when the CPU is at 100% utilisation. The Intel OpenCL runtime should work, though. Make sure you restart your machine if you haven't already and still want to persue CPU support
RE: Hashcat do not recognize my CPU with OpenCL - clenet - 01-17-2024
Yes, i restarted my machine, unsucessfully
I want to pursue with CPU support for an internal need
I downloaded the new version of Intel OpenCL runtime and i suspect a bug with this version
I didn't find a way to download an earlier version
How can I check if hashcat properly work with OpenCL runtime ?

Windows or Linux?
Have you seen this

Yes, it is the url followed to download w_opencl_runtime_p_2024.0.0.49848.exe

I would try installing fresh Windows in a separate partition (just for a test) and not connect to Internet at all. Then install OpenCL runtime.
Also you can try this old runtime (it works for non-Intel CPUs as well)

RE: Hashcat do not recognize my CPU with OpenCL - clenet - 01-18-2024
I installed OpenCL version 18.1 following your link and now my CPU is recognized but not my GPU!
How to have both?

when i remember myself right, on these "combined CPU/GPU" laptop APUs it doesnt really matter what kind of device backend you use as its physical the same and CPU has the advantage of providing more ram to the process
see the data on memory total and allocatbale compared GPU <-> CPU
