Hi there,
got me a Titan Black and upgradet from Ubuntu 12.04 to 14.04 everything working fine so far exept that the opencl option for the pyrosolver returns an error. It seems Houdini has problems finding the opencl driver.
I attached the Houdini infotext file. In it it says:
No Configured OpenCL Device
A middelmouse klick over the pyrosolver gives me this:
no opencl platform found (-32)
Opencl Exeption clfinish (-36)
I tried several different Nvidia drivers and different versions of Houdini but the error persists.
The driver I'm running now is the 340 one. Houdini is now the latest daily build which is 521.
Any suggestions would be great.
Cheers
Ubuntu 14.04 opencl issue

Thank you for the reply, did some googling on the topic and found that this seems to be an Nvidia driver bug affecting only the open Cl computing. It is there since driver version 313. Today I installed version 343.22 and there still is no change. Nobody seems really to be interested in removing this. Guess for now the 6GB of ram on the Titan are a waste. Hope they solve this soon because I am curious how large sims one can run on the GPU.

I'm not the most experience with this, but I think I have it working. I recently built a new system with ubuntu 14.04 on a GTX970. Mine would error out the same way until I installed additional CUDA drivers.

Currently seems to be working, but I ended up going through an xorg ppa for my drivers. Here's a link for that:

Hope this helps!
