Hi, there. I need help getting double precision working in my openCL application on the GPU.
Double precision works fine on the CPU, but when I try to run it on the GPU it fails.
My Graphics Cards is ATI Radeon HD5850 which is as far as I can tell, should work http://en.wikipedia.org/wiki/Comparison_of_AMD_graphics_processing_units#Evergreen_.28HD_5xxx.29_series
It tells me it can't enable cl_khr_fp64 or cl_amd_fp64, but since my graphics card should be able to run 64bit, I'm at loss for why.
I'm using the 13_1 drivers for my graphics card, and I have version 2.8 of the SDK.
Windows 7 64 bit
ATI Radeon HD5850
Visual Studio 2010 Professional
13_1 mobility Graphics drivers.
AMD APP SDK 2.8
Thanks in advance, any help is appreciated.
