OpenCL:在内核中手动引发异常 [英] OpenCL: Manually throw an exception in kernel

问题描述

是否可以仅出于调试目的在OpenCL中手动引发异常?我的代码中出现一个非常奇怪的错误:当我计算两个双精度值并将它们加起来时，主机报告"CL_OUT_OF_RESOURCE".但是，如果我不添加这两个值，则主机不会报告任何错误.

Is it possible to manually throw an exception in OpenCL, just for debugging purposes? I am having a very strange error in my code: when I computed two double values and add them up, the host reports "CL_OUT_OF_RESOURCE". However if I don't add these two values, the host doesn't report any error.

推荐答案

OpenCL不支持异常-它基于C99语言.

Exceptions are not supported in OpenCL - it is based on the C99 language.

在AMD GPU上，您可以在内核内部使用printf-请参见cl_amd_printf扩展名.要使用它，请将其放在.cl文件的顶部:

On AMD GPUs you can use printf inside the kernel - see the cl_amd_printf extension. To use, put this at the top of your .cl file:

#pragma OPENCL EXTENSION cl_amd_printf : enable
