为Nvidia GPU安装OpenCL
为Nvidia GPU安装OpenCL
提问于 2018-01-26 00:56:40
我为Nvidia GPU (GTX 285)安装了OpenCL，但是OpenCL不能工作。
clinfo (和其他应用程序)显示了这个错误：
X server found. dri2 connection failed!
DRM_IOCTL_I915_GEM_APERTURE failed: Invalid argument
Assuming 131072kB available aperture size.
May lead to reduced performance or incorrect rendering.
get chip id failed: -1 [22]
param: 4, val: 0
...
beignet-opencl-icd: no supported GPU found, this is probably the wrong
opencl-icd package for this hardware
(If you have multiple ICDs installed and OpenCL works, you can ignore this message)我安装的软件包是：

NOTE: your OpenCL library declares to support OpenCL 1.2,
but it seems to support up to OpenCL 2.1 too.

我在Ubuntu上的openCL支票列表：
- 运行这些工具和应用程序的用户需要访问视频设备。对于Ubuntu来说，这需要将他放入组“视频”中。
- 如果您想要访问Intel CPU上的GPU，请激活BIOS中的“车载视频”。
- 有通过XServer查找ICD的启发式方法。因此，通过使用"DISPLAY= clinfo“之类的命令取消显示变量可以帮助您根据终端访问(SSH或直接访问或在X内)提供帮助。
- 使用专有的NVidia驱动程序。新来的不支持openCL到2020/1
