OpenCL on an Intel i5 laptop
« on: December 26, 2019, 02:32:44 PM »
I have a desktop with an AMD A6-5400K APU with Radeon(tm) HD Graphics , when I runGeek3D GPU Caps Viewer (1.43.10) I get under Opencl the following:
Number of CL platform: 1     AMD accelerated Parallel processing
Number of CL devices: 2       1 Caicos, 2 AMD A6-5400K APU with Radeon(tm) HD Graphics
With this configuration I have no problem at all activating OpenCL support and OpenCL scheduling profile when running Darkroom
The story is completely different on my Laptop with an Intel i5, OpenCL is not available under Darkroom.
Here is what I get when I runGeek3D GPU Caps Viewer (1.43.10) under Opencl:
Number of CL platform: 1     AmD accelerated Parallel processing
Number of CL devices: 1      Intel® Core ™ i5- 3210M CPU @ 2.50 GhZ
It looks like that there is a conflict between the AMD video card and Intel processor! And if in the affirmative I would appreciate any work around or solution to this problem. The result of this situation: I am getting a better performance on the desktop when running Darkroom when compared to the sluggish performance on the much powerful Laptop.

What is the website of "Darkroom"?
Is there no support forum?
Export GPU data from GPUCapsViewer as text file and upload it, so we can take a look at it.

I just wrote Darkroom instead of Darktable, sorry about that. the Web site is Darktable.org, and yes there is a support forum but I had no luck there.

I can't find a way to attach the 2 text files with GPU data from GPUCapsViewer, so I copied them in this response instead. I hope I have the correct info because I am not too familiar with the Viewer. I just noted that under OpenCL we have 2 devices in the desktop including Caicos while in the laptop it is not listed I just have Intel i5 device in the viewer. Now the two files

The first one covers the desktop
