Hi guys,

I'm trying to get opencl running for grain simulations in DOPs, however I'm always getting the typical “Unable to load HFS OpenCL platform.” error.

Using a GForce GTX1060 in my laptop on Windows 10.
Can somebody please point me towards how to fix this?
Thanks!

Here are my stats from when I click on ‘about’ in Houdini:

That graphics driver version does that - 385 will fail OpenCL at all times, the 382 branch works the first time then fails but the 375, 378 or 37-something should work. You can also use OpenCL CPU instead, so set the environment to:

HOUDINI_OCL_DEVICETYPE=CPU

Thanks for the answer, I'm going to install an older driver and see if that works!

Has this been resolved. I am having this issue on my dell precision 7720 workstation. This is the first statement that pops up in Houdini:

Unable to load HFS OpenCL platform.

It looks like HOudini is having a hard time choosing which video card to utilize. And this is from quick research online.

Try to add this environment variable to your 'houdini.env' file:
HOUDINI_USE_HFS_OCL=0
