error : identifier “atomicAdd” is undefined under visual studio 2010 & cuda 4.2 with Fermi GPU

Question

I was trying to compile some CUDA codes under visual studio 2010 with CUDA 4.2 (I created this CUDA project using Parallel Nsight 2.2), but I encountered an atomic problem "error : identifier "atomicAdd" is undefined", which I still can't solve after checking several forums.

So I tried to get some information from CUDA SDK Samples. First, I ran the simpleAtomicIntrinsics sample in CUDA SDK, which passed its test. Then, I copied all the files in this sample 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 samples such as clock, matrixMul, etc. under this vs2010 CUDA Project. (This means the include path is set correctly)

I googled it and found the following link Some issue with Atomic add in CUDA kernel operation. I changed the properties of both project and the .cu file according to it, but still can't solve the problem.

Any suggestion?

Answer 1

Atomics are unavailable under compute architecture 1.0, but you're still trying to compile for it according to your build log. Try removing references to compute_10 and sm_10 from your CUDA project properties and compiling for just compute architecture 2.0 (GeForce 400 series and newer).

Answer 2

Try to compile with the flag -arch sm_20

Answer 3

"Atomics are unavailable under compute architecture 1.0, but you're still trying to compile for it according to your build log. Try removing references to compute_10 and sm_10 from your CUDA project properties and compiling for just compute architecture 2.0 (GeForce 400 series and newer)." It's absolutely right,BTW,if you guys are compiling rodrigob_doppia's source code(boosted_learning),you can just add the line in your machine configuration: set(CUDA_NVCC_FLAGS "-arch=sm_20" CACHE STRING "nvcc flags" FORCE) Actually,it is set to switch the arch flag to sm_20,just the same as the saying above.
