嗯，汇编2.0

也是杯具2.0

看不明白这是啥玩意，好像挺专业的。

站长居然不给个本地下载，喷、喷、喷！

ATI专业卡

AMD 把有限的人力投到游戏卡支持OPENCL 上。实在是无谓.

据说R600/RV670被抛弃了呀。。。相比CUDA依然是不完善呀不完善。。。

5770、5750不支持double precision

RV830 不支持 DP FP。

不过 opencl 这里的主要问题是，amd 目前的这个 SDK 2.0 其实并未提供 DP 支持， 严格来说它只是提供了四则运算的 DP 支持，而 opencl 中其实有很多的函数，例如三角函数，这部分 SDK 2.0 就未能支持了。

正式的 DP 支持应该在 2010 年上半年，拖沓这么久的原因估计是 AMD 的 RV870 DP 单元有些地方没有完全遵循 opencl 1.0 的要求，需要一些软件上的动作。

Details and Recommendations


This preview feature is being offered to developers by AMD and does not constitute support for any official optional double-precision floating point extension as defined in the OpenCL™ 1.0 Specification. This feature may behave differently from what is documented in the specification.

Double-precision floating point addition, subtraction and multiplication operators are available for use in OpenCL™ C kernels.

Double-precision floating point built-in function support will be added in a future release.

Use of double-precision floating point arithmetic on GPUs other than ATI Radeon™ HD 5800 series GPUs and ATI Radeon™ HD 5900 series GPUs may result in unexpected behavior.

相关应用需不需要安装这个？

感觉没什么用途，现在对所谓的通用运算一点性趣都没...........

哎
