I'm getting no OCL(Cuda) on Linux and just double checking that the driver version can affect this? Installation of Nvidia drivers can be terrible so before diving into that, want to make sure.

No OpenCL platform has the specified device type (HOUDINI_OCL_DEVICETYPE): GPU. Falling back to built-in CPU OpenCL driver.

OpenGL Vendor: NVIDIA Corporation
OpenGL Renderer: GeForce GTX 1080 Ti/PCIe/SSE2
OpenGL Version: 4.6.0 NVIDIA 390.25
OpenGL Shading Language: 4.60 NVIDIA
Detected: NVidia Consumer

390.25.0.0

Which flavor of Linux are you running?

It's Kubuntu upgraded from Ubuntu


Platform: Linux 2.6.32-573.3.1.el6.x86_64
Operating System: Ubuntu 17.10

I believe you also need to install the Nvidia OCL package for that driver version, try apt-cache search nvidia to get the exact package name.

Hmmm weird. I seem to have failed trying to install the Nvidia OCL package and somehow ended up with 390.48 which also was failing for OCL. Have installed 384.130 and OCL is working again, but obviously without OGL 4.6.

update: 396.18.0.0 works fine too

Any ideas for stable OCL GPU drivers? My setup has intermittent faults where GPU-OCL will work for a bit then stop working. CPU-OCL always works. Rebooting fixes things.

396.24.2.0 - Kunbuntu. H17.0.370

UPDATE: appears ‘suspending’ the system makes openCL GPU fail
