问题
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.
So now I have the following "minimal" problem:
I opened the simpleCUBLAS example out of the NVIDIA CUDA SDK (4.2) to test if I can reproduce the problem .
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 an Speicherposition 0x003bf704..
7 times
so to my specs:
I use a GTX 460 for computing, compile with sm_20 use VS2010 on Windows 7 64-bit and nvcc --version gives me:
nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2011 NVIDIA Corporation Built on Fri_Jan_13_01:18:37_PST_2012 Cuda compilation tools, release 4.1, V0.2.1221
this is my first time posting here so I apologize for the horrible format it is posted
回答1:
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.
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.
