第一章 GPU计算与OpenCL 什么是OpenCL OpenCL全称OpenComputingLanguage即开放计算语言。OpenCL为异构平台提供了一个编写程序,尤其是并行程序的开放的框架标准。OpenCL所支持的异构平台可由多核CPU、GPU或其他类型的处理器组成。OpenCL由两部分组成,一是用于编写内核程序(在OpenCL设备上运行的代码)的语言,二是定义并...

For the GPU to transfer host memory to device memory (for example, as a parameter to clEnqueueReadBuffer or clEnqueueWriteBuffer), it first must be pinned (see section ). Pinning takes time, so avoid incurring pinning costs where CPU overhead must be avoided. When unpinned host memory is...
but I've learned that often AMD doesn't necessarily support a lot of features with their Linux drivers (for example the FirePro W5100 is not OpenCL 2.0 capable on Linux, even though AMD advertises that it is: https://community.amd.com/t5/firepro-development/opencl-2-0-on-amd-firepro-...
似乎想要装pyopencl,得先装opencl,于是amd官网下opencl sdk(2.9.1,版本在表格里,一目了然),安装路径似乎没得选,在program files x86 文件夹。继续报错。 这次的报错报到VS里了,我是不是该庆幸装了VS社区版……说CL/cl.h 找不到。试图打开的程序也叫cl…… ...
