异常（第一次机会）... cudaError_enum在内存 [英] exception (first chance) ... cudaError_enum at memory

问题描述

所以我正在做一个项目，这是吐出这个错误，一些研究表明，问题在于cublas库。

So I am working on a project which is spitting me out that error, after some research showed that the problem lies with the cublas library.

现在我有以下的最小问题：

So now I have the following "minimal" problem:

我打开了NVIDIA CUDA SDK（4.2）中的simpleCUBLAS示例来测试我是否可以重现这个问题。

I opened the simpleCUBLAS example out of the NVIDIA CUDA SDK (4.2) to test if I can reproduce the problem .

程序本身工作，但VS2010给了我一个类似的输出：

the programm itself works but VS2010 gives me a similar output:

Eine Ausnahme（erste Chance）bei 0x75e3c41f in simpleCUBLAS.exe：Microsoft C ++ - Ausnahme：cudaError_enum a Speicherposition 0x003bf704 ..

7次

我的规格：

我使用GTX 460进行计算，使用sm_20编译，在Windows 7 64位
使用VS2010， nvcc --version给我：

I use a GTX 460 for computing, compile with sm_20 use VS2010 on Windows 7 64-bit and nvcc --version gives me:

推荐答案

您所做的观察与在CUDA库中正确捕获和处理的异常有关。在某些情况下，它是CUDA GPU操作的正常部分。正如您所观察到的，您的应用程序不返回API错误并正确运行。如果你不在VS环境中可以报告这一点，你根本不会观察到这一点。

The observation you are making has to do with an exception that is caught and handled properly within the CUDA libraries. It is, in some cases, a normal part of CUDA GPU operation. As you have observed, your application returns no API errors and runs correctly. If you were not within the VS environment that can report this, you would not observe this at all.

这是CUDA下的正常行为。我相信有一些尝试在CUDA 5.5中消除它。你可能希望尝试，虽然它不被认为是一个问题的方式。

This is considered normal behavior under CUDA. I believe there were some attempts to eliminate it in CUDA 5.5. You might wish to try that, although it's not considered an issue either way.
