我正在尝试使用 OpenCL 示例 HelloWorld 来查看是否一切正常。我没有编译问题,但是,我在 clCreateCommandQueue() 中有一个 CL_OUT_OF_HOST_MEMORY。

这是我得到的

[thomas@thomas-OptiPlex-9020:/opt/AMDAPPSDK-3.0/samples/opencl/bin/x86_64]$ ./HelloWorld
input string:
GdkknVnqkc

output string:
�����
Passed!

我正在使用 Ubuntu 16.04.2 LTS 和 Oland AMD Radeon HD 8600 系列。我在这里安装了最新的 AMDGPU-PRO 驱动程序以及用于 64 位 Linux 的 AMD APP SDK 3.0。clinfo 输出如下所示。
