[darktable-user] OpenCL on Intel Core i7-6770HQ with Iris Pro 580
Hello, I tried to get darktable to use OpenCL on my shiny new system. It sports an Intel Core i7-6770HQ CPU with and Iris Pro 580 GPU part. Darktable recognised the device after I installed Intel's drivers. But running darktable with "-d opencl" shows that it discards the device. Is that because it wouldn't provide any performance gain? Darktable didn't give a specific reason. If not, is there some other way I can get more information on why dt doesn't want to use OpenCL on this system?

Hi, please post what 'darktable -d opencl' says. Ulrich Am 26.05.2016 um 11:06 schrieb Christian von Kietzell: Hello, I tried to get darktable to use OpenCL on my shiny new system.

Re: [darktable-user] OpenCL on Intel Core i7-6770HQ with Iris Pro 580
Hi, only your CPU has been detected by your OpenCL driver. We do not use OpenCL on CPU as it would bring a severe slow-down of darktable compared to our hand-optimized code. Your OpenCL setup seems not to take notice of the Iris Pro. But even if it would: our experience with the (free) Beignet OpenCL implementation for Intel GPUs in its current state is discouraging. There is little chance that it will work.

[darktable-user] something wrong with hotpixels module ?
hi, yesterday i upgraded to dt version 2.1.0+1114-g35cc641 since then, i am experiencing a lot of hot pixels in my photos. i've set my dt to turn hotpixels on by default a long time ago, and havent seen them for quite a while. but last night and today i am seeing then at the dark areas of my photos. is there something wrong with the module or is it my mistake? i can send samples, if needed. best regards, andre felipe darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org

We have good experience with AMD and Nvidia. The proprietary drivers of both vendors run well with a noticeable speed-up (depending on hardware, of course). As said experience with Intel is not good due to the lack of working OpenCL drivers on Linux platforms.
