在哪里可以找到OpenCL(Nvidia)中错误代码的字符串?

问题描述

在NVIDIA GPU上运行一个简单的OpenCL矩阵乘法代码，我得到错误代码-30.我想知道这段代码的含义.我确定与此代码(int)相对应的字符串必须存储在某个位置.有人可以帮助我解释此代码吗?一旦知道了此错误的含义，便可以轻松调试代码.

Running a simple OpenCL Matrix Multiplication code on NVIDIA GPU, I get error code -30. I want to know what is the meaning of this code. I am sure the string corresponding to this code (int) must be stored somewhere. Can someone help me in interpreting this code? Once I know what this error mean I can debug my code easily.

有nVIDIA版本和AMD版本.但是我更喜欢以通用的方式开源.

There is an nVIDIA version and an AMD version of these. But I prefer to do it OpenSource and in a generic way.
