I tried uninstall/reinstall Nvidia driver, reinstall SVP4, reboot, run as administrator, but still the same. And my machine doesn't have a Intel graphic card and Intel driver.

Any suggestions?

Re: SVP4 won't start

The last line in your log is OpenCL initialization:

20:23:38.757 [i]: Video: reading OpenCL info...

Looks like you have corrupted OpenCL. OpenCL is a part of GPU drivers.
You need to uninstall all GPU drivers and install it again from official site.
I recommend to use DDU to completely unistall GPU drivers:
https://www.guru3d.com/files-details/di … nload.html

If nothing helps you, you can launch C:\Program Files (x86)\SVP 4\utils\clinfo64 form command line and post the output here.

I tried reinstall my NVIDIA driver several times, but it didn't work.

Re: SVP4 won't start

Finally found the "solution" in Intel's forum:https://community.intel.com/t5/OpenCL-f … 9711#M5258

I'll post it here:

If you're comfortable mucking with the registry, the easiest thing to do is to modify:

HKLM\SOFTWARE\Khronos\OpenCL\Vendors (for 64-bit applications)
or

HKLM\SOFTWARE\Wow6432Node\Khronos\OpenCL\Vendors (for 32-bit applications)
These registry keys should contain one REG_DWORD value for each OpenCL platform.  If you change the REG_DWORD value for a platform from 0 to 1 then that platform will no longer enumerate.  The nice thing about this method is that if you change your mind, you can re-enable the platform by simply changing the value from 1 back to 0.

Everything works fine for me now.

It seems that SVP4 won't start if there are more than 1 opencl installed. Will there be any fix to it?

SVP won't start if OpenCL driver crashes due to misconfiguration.

SVP won't start if OpenCL driver crashes due to misconfiguration.

I don’t think it’s that simple. I recently installed Intel oneAPI with oneDNN, OpenCL, OpenMP etc. to compile Pytorch from source. Since then I can’t start SVP 4. At the very least SVP4 should provide better messages.

Anyway, that registry the previous commenter hinted to had entries for “C:\Program Files (x86)\Intel\oneAPI\compiler\latest\windows\lib\x86\intelocl32.dll” and “C:\Program Files (x86)\Intel\oneAPI\compiler\latest\windows\lib\x86\intelocl32_emu.dll”, I disabled the emu and SVP now starts.
