I’m using cudaFFT with multi-GPUs, I have trouble when i use cudaFFT, it shows runtime error in CUDAFFT. The same code work fine with single GPU. Can some one tell me what is the error about, or sheet a light for what cause the error, and what i should do
cufft: ERROR: /root/cuda-stuff/sw/rel/gpgpu/toolkit/r2.0/cufft/src/plan.cu, line 41
cufft: ERROR: CUFFT_INTERNAL_ERROR
I use CUDA 2.0b version. I use an iterative method that run GPU threads every iteration, inside the thread I create cudaFFT plan, and use that one to perform cudaFFT.
