When I debug this program, it fails when running at cudaMemcpy with the error information cudaSafeCall() Runtime API error 11: invalid argument. Actually, this program is transformed from another one that can run

correctly. But in that one, I used two variables S* d and S h[3] in the main function instead of in the class. What is more weird is that I implement this class A in a small program, it works fine. And I've updated my driver, error still exists. Could anyone give me a hint on why this happen and how to solve it. Thanks. memory cuda invalid-argument share|improve this question edited Oct 29 '13 at 8:03 einpoklum 10.8k953114 asked May 14 '12 at 8:12 TonyLic 342419 By the way, the cudaMemcpy will reture cudaErrorInvalidValue. –TonyLic May 14 '12 at 8:31 2 Where is the line A a;? Is it inside a function, or is it global? If it is global, then the constructor might be called before you have a valid device context (I'm not sure about this, but it's possible). If that's the case, then the d pointer passed to cudaMemcpy would be invalid. –harrism May 29 '12 at 10:48 Can you post your CUDA configuration you use please? I can't reproduce your error with an old GeForce 9400m and CUDA 5.0 preview. –jopasserat Jun 15 '12 at 12:06 add a comment| 1 Answer 1 active oldest votes up vote 3 down vote Because the memory operations in CUDA are blocking, they make a synchronization point. So other errors, if not checked with cudaThreadSynchonize, will seem like errors on the memory call
