在 Ubuntu 17.04、Intel 上安装 OpenCL
我正在尝试在 ubuntu 17.04 上安装 OpenCL：
$ lshw :
*-cpu
product: Intel(R) Core(TM) i5-3210M CPU @ 2.50GHz
vendor: Intel Corp.
physical id: 1
bus info: cpu@0
size: 2899MHz
capacity: 3100MHz
width: 64 bits
*-display

width: 64 bits
clock: 33MHz

到目前为止，还没有找到任何文档。英特尔的“install.sh”报告不支持的操作系统。
---- 根据@Thomas，我已经安装：apt-get install beignet clinfo
到目前为止似乎还没有 opencl gpu 支持
以下是 clinfo 输出：

答案1
您可以安装beignet供英特尔使用的软件包，这clinfo将有助于检查所识别的内容。
apt-get install beignet clinfo
然后运行clinfo检查openCL设备。
clinfo
根据您的计划，您可能还需要安装开发包或其他库。
apt-get install beignet-dev
对于您感兴趣的库或程序，请使用以下命令来查找它们。
apt-cache search opencl
