use*_*757 1 linux virtual-machine opencl ubuntu-14.04
PC 配置：AMD 双核 E-350 1.6Ghz AMD 6310 高清显卡
我在 Windows 8 之上的 VMware Player 上运行 Ubuntu 14.04，并试图弄清楚我是否可以在 ubunutu 上运行 OpenCL，即使用 VM。
我正在阅读一本关于如何安装 OpenCL 的手册，第一步给出了这个输出。有人可以看到输出并告诉我应该做什么吗？我可以在 VM 上运行 OpenCL 吗？
1）首先，我们需要检查我们的系统配置，以确定是否可以在我们的机器中安装 OpenCL。我们可以在终端上运行“Hardinfo”命令来获取系统配置的完整摘要。如果我们的系统中没有安装 Hardinfo 命令，那么我们可以通过在终端上运行以下命令来轻松安装它： sudo apt-get install hardinfo 2）如果我们的系统可以支持 OpenCL 那么我们可以进入 OpenCL 的实际安装. 3) 从英特尔网站下载面向 OpenCL 应用程序的英特尔 SDK 。.....
varun@varun-virtual-machine:/$ hardinfo
当前未安装程序“hardinfo”。您可以通过键入以下内容进行安装：sudo apt-get install hardinfo
varun@varun-virtual-machine:/$ sudo apt-get install hardinfo

您可能想要运行“ apt-get -f install”来更正这些：
以下软件包具有未满足的依赖项：
fglrx : Depends: fglrx-core but it is not installable
Recommends: fglrx-amdcccle but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
从 Ubuntu 18.04 开始，要获得在仅 CPU 环境（如虚拟机）上运行的 OpenCL 版本，您需要做的就是：
sudo apt-get install libpocl2
然后clinfo会告诉你，例如：

非常感谢PoCL 团队让这一切成为可能！
可以在虚拟机中运行 OpenCL，但您只能访问 CPU 设备。Intel SDK 不能工作，因为它有严格的硬件要求，但 AMD SDK 安装得很好。我在 Windows 8 + VirtualBox 下的 Ubuntu 14.04 VM 上使用 AMD-APP-SDK-v2.8-RC-lnx64 运行。您可以从这里获取 SDK：http : //developer.amd.com/tools-and-sdks/opencl-zone/amd-accelerated-parallel-processing-app-sdk/download-archive/
