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.

 

 

Specs:

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.
