Finally!
What Linux distro this is built for? I am having issue on Ubuntu 16.04B2. It does not want to start.
Code: Select all
This application failed to start because it could not find or load the Qt platform plugin "xcb".
Available platform plugins are: linuxfb, minimal, offscreen, xcb.
Reinstalling the application may fix this problem.
Aborted (core dumped)

Odd, 8 GB should be plenty enough. Did you check the render log window?

Have you updated your drivers to the latest?
Seems that way... unless I'm missing something.

And yes, the kernel builds are quite a bottleneck at the moment, looking forward to optimisations there. By the way, if you let that scene render a little longer, the rendering speed should settle and might increase further. :)
I tested to let it run longer. The Samples / Sec level off at around 9500.
Thats quite nice!

Given what my hardware, GPU rendering is much slower than the CPU.
The image of the MacLaren after 7min. It is much more yield than the other well after 2h, 34min. The GPU is intercepted but the CPU is much more efficient, at least for now!
Do you have an explanation? Thank you.
Looking at this specs
http://www.intel.com/content/www/us/en/ ... 05524.html
For 2nd generation Intel Core HD3000 didn't support OpenCL, meaning the CPU is used for computation, obviously less efficiently respect native code.
It's the same on mine i5 2520M where I did find in Indigo the two CPU core available for GPU accelleration, but not the iGPU HD3000.

Quadro M5000 does support OpenCL 1.1, if I good remember Indigo request OpenCL 1.2, that's probably why only the CPU is used.
Edit: above link it's on k5000, can't find official M5000 specs on OpenCL version support.

Thanks for the reply.
The alternative is an external GPU go Thunderbold Version 1 or a newer computer!

Here is a lightweight abstract scene for testing.
Feel free to use it guys. (for testing ;P)
What a day!! :)

Snorky, not sure but have you tried installing CUDA? I know Zom-B got a GTX 660 working fairly well.

Yup, my system (CPU&GPU) only supports oCL 1.1.
So without oCL 1.2 support, there's no alternative for acceleration with Indigo (CUDA, limited oCL 1.1)? Only pure CPU?
For those who wonder, here's Khronos list of
openCL_1_2+ Conformant Products

I think the requirement might be OpenCL 1.1 actually, but regardless a M5000 is a new Maxwell card and should work with Indigo. Have you tried a simpler scene - like the default material scene?

I have scenes that work when the CPU opencl is used and not GPU, even low memory scenes. Can it be because CPU uses 1.2 and my GPU 1.1 specification?
BTW the image only updates when the blue bar reaches the end.
