Re: Blender Cycles(Opencl on AMD GPUS)
Same OpenCL version, same speed, same limitations. The promised "mid July" release became "mid August" and didn't deliver anything. I just have enough, after 2 years of waiting. It's about time to...

View ArticleKaveri - global mem size
Hi, I use openCL on A10-7850k Kaveri GPU in 64 bit address mode. When I query global mem size like this: cl_ulong globalSize; clGetDeviceInfo(m_deviceId, CL_DEVICE_GLOBAL_MEM_SIZE, sizeof...
View ArticleRe: Kaveri - global mem size
The global memory is the memory dedicated to your GPU. For a discrete desktop GPU card, it is the memory soldered on the card for example (VRAM). So it's normal: your APU doesn't have access to all...

AMD just released CLOC (HSAFoundation/CLOC · GitHub). Can any one here try compiling blender kernel with that? I'm wondering if that compiler is any better than the shipping compiler and eventually...

I'm here to do little more than add my voice to the crowd. I very much prefer AMD to Nvidia and find the proprietary CUDA framework to be highly distasteful. My dislike of CUDA means that AMD would...

View ArticleRe: Kaveri - global mem size
I think that your results are normal. Kaveri has support for virtual memory, so even though the GPU doesn't have 6GB but 512MB, it is able to make like it has 6GB: every time it accesses some memory...

Thank you very much, I will keep this in mind. As long as no other cards get released, that's the most effective way to do this.

It is not meaningless, it's exactly what's written.CL_DEVICE_GLOBAL_MEM_SIZE: size of the global memory available to the CL device.GLOBAL memory is not "system global" it's "offchip" device memory.My...
