Thanks Markus ... this is all a bit over my head and a tad frustrating. My system may be a bit complicated as I am running Bumblebee in an effort to achieve good battery performance as well as having the ability to use OpenCL as needed. My nvidia.icd appears to have not even been located in the

I am filing a bug report against the ubuntu package right now. It deletes the nvidia.icd symlink in /etc/ all the time and now it does not even create sane symlinks for libnvidia-opencl. I just "fixed" the issue by manually creating a nvidia.icd containing the line "libnvidia-opencl.so.304.88" Reg

Hi, config parameter opencl_avoid_atomics is your friend :) As Jo has pointed out some of our OpenCL code (bilateral filter) runs best using a specific non-standard type of atomic operation. If your hardware does not support this, a slower emulation with standard atomics is used. Some systems

The IIs is a different camera, same sensor but lacks the AA filter, so it isn't surprising that the results differ a bit. I think it would be great if there was a way to use multiple shotss, since making them is trivially easy and profiling takes a long time anyway and is only done once. On
