Error: identifier "atomicAdd" is undefined under visual studio 2010 & cuda 4.2 with Fermi GPU

Question

I tried to compile some CUDA codes in visual studio 2010 with CUDA 4.2 (I created this CUDA project using Parallel Nsight 2.2), but I ran into the atomic problem "error: identifier" atomicAdd is undefined ", which I cannot solve after checking multiple forums.

So, I tried to get some information from the CUDA SDK Samples. First, I ran a simpleAtomicIntrinsics sample in the CUDA SDK, which passed the test. Then I copied all the files in this example to a new CUDA 4.2 project in visual studio 2010 and compiled them. Here is the result.

By the way, I can run other patterns like clock, matrixMul, etc. as part of this project vs2010 CUDA. (This means that the enable path is set correctly)

I looked through it and found the following link. Some problem with Atomic add in the operation of the CUDA kernel . I changed the properties of both the project and the .cu file to suit it, but still cannot solve the problem.

Any suggestion?

Answer 1

Atomics are not available in Computing Architecture 1.0, but you are still trying to compile it according to your build log. Try to remove references to compute_10 and sm_10 from your properties of the CUDA project and compile only for computing architecture 2.0 (GeForce 400 series and newer).

Answer 2

Try compiling with the -arch sm_20 flag

Answer 3

"Atomics are not available in Computing Architecture 1.0, but you are still trying to compile it according to your build log. Try removing the references to compute_10 and sm_10 from your CUDA project properties and compiling it only to calculate architecture 2.0 (GeForce 400 series and later)" . This is absolutely true, BTW, if you guys are compiling the source code of rodrigob_doppia (boosted_learning), you can simply add a line to your computer's configuration: set (CUDA_NVCC_FLAGS) -arch = sm_20 "CACHE STRING" nvcc flags "FORCE) In fact, it is configured to switch the arch flag to sm_20, just like the above.
