CUFFT_EXEC_FAILED message reported when using libcufft.so.2.2 as follows:
cufftHandle plan; cufftPlan1d(&plan, 1024, CUFFT_R2C, 1); cufftExecR2C(plan, dataInput, dataOutput); //destroy the plan cufftDestroy(plan);
Here is the reported error:
“cufft: ERROR: /root/cuda-stuff/sw/rel/gpgpu/toolkit/r2.2/cufft/src/execute.cu, line 1070
cufft: ERROR: CUFFT_EXEC_FAILED
cufft: ERROR: /root/cuda-stuff/sw/rel/gpgpu/toolkit/r2.2/cufft/src/cufft.cu, line 147
cufft: ERROR: CUFFT_EXEC_FAILED”
For some reason this error only reports once. Even when the same sequence (listed above) is called 100,000 times the error posted above only appears once. The output values are correct for both 1 run or 100,000 runs so cufft seems to be successful despite this indication.
Anyone run across this symptom using RHL 5.3 x86_64 with cufft 2.2?
Thank you for your thoughts. ;-)
