OpenCL安装指南
可以选择一种或两种方式使用OpenCL： 1.在Ubuntu 16.04 64位上安装OpenCL 2.Docker使用OpenCL
在Ubuntu 16.04 64位上安装OpenCL
# below instructions refer linux安装opencl：ubuntu14.04+opencl1.1 - qccz123456的博客 - CSDN博客
# http://blog.csdn.net/qccz123456/article/details/52606788
$ sudo apt-get update
$ sudo apt-get install build-essential g++ cmake
$ sudo apt-get install clang libclang-3.4-dev libclang-dev libclang1
$ sudo apt-get install ocl-icd-opencl-dev ocl-icd-libopencl1
$ sudo apt-get install opencl-headers ocl-icd-dev ocl-icd-libopencl1

# http://www.linuxidc.com/Linux/2017-03/141455.htm
$ sudo apt install ocl-icd-libopencl1
$ sudo apt install opencl-headers
$ sudo apt install clinfo
$ sudo apt install ocl-icd-opencl-dev
$ sudo apt install beignet
通过Docker使用OpenCL
使用Docker十分方便，你无需为所有OpenCL进行配置和安装环境。当然，首先安装Docker https://docs.docker.com/Community Edition，然后在DockerHub中搜索相关映像。 https://hub.docker.com/ 完成Docker安装后，请按照chihchun / opencl-intel中的说明进行操作。如果一切正常，请在命令行中使用以下命令：
$ docker run -t -i --device / dev / dri：/ dev / dri \
chihchun / hashcat-beignet hashcat -b
它将打印与验证安装类似的消息。
验证安装
使用以下说明，成功安装将显示以下相同消息：
$ clinfo

NOTE: your OpenCL library declares to support OpenCL 1.2,
but it seems to support up to OpenCL 2.1 too.
如何在GCC中编译OpenCL示例？
准确地说，OpenCL中的内核编译是在运行时进行的（库调用）。
在Gcc中，仅需标头（Kronos站点上的可用标头）即可进行编译。但是，要进行链接，您必须安装与OpenCL兼容的驱动程序。
在Makefile中：
- 对于Mac OSX：-framework OpenCL
- 对于Linux：-lOpenCL
其他问题
git错误：无法自动检测电子邮件地址
yuanshuai@firefly:~/code/OpenCL-101$ git commit -m "update README.md"
Please tell me who you are.
Run
git config --global user.email "you@example.com"
git config --global user.name "Your Name"
to set your account's default identity.
Omit --global to set the identity only in this repository.
fatal: unable to auto-detect email address (got 'yuanshuai@firefly.(none)')
按照上面的说明进行操作后，它仍然出现相同的错误消息。本项目重置user.email并user.name使用git config --local user.email "you@example.com"，git config --local user.name "Your name"
