CUFFT_INTERNAL_ERROR while running cufftPlan1d

Accelerated Computing GPU-Accelerated Libraries

Hi,

I’m having trouble running the below code:

#include "cufft.h"

#include "cuda_runtime.h"

#define NX 256

#define BATCH 10

int main()

{

  cufftHandle plan;

  cufftComplex *data;

  cudaMalloc ((void**)&data, sizeof(cufftComplex)*(NX)*BATCH);

  cufftPlan1d(&plan, NX, CUFFT_C2C, BATCH);

  cufftDestroy(plan);

  cudaFree(data);

}

The error message I’m seeing:

cufft: ERROR: /root/cuda-stuff/sw/gpgpu_rel1.1/cufft/src/config.cu, line 106

cufft: ERROR: CUFFT_INTERNAL_ERROR

cufft: ERROR: /root/cuda-stuff/sw/gpgpu_rel1.1/cufft/src/cufft.cu, line 94

cufft: ERROR: CUFFT_INVALID_PLAN

Does anyone have any idea why this is happening, and how can I fix it?

Thanks!

Your code is fine, I just tested on Linux with CUDA 1.1:

gcc fft.c -I/usr/local/cuda/include -L/usr/local/cuda/lib -lcufft

It runs without errors.
Which OS are you using?

Hi,

I’m using Linux 2.6.18 version.

And, I used the same command but it’s still giving me the same errors.

Thanks.

Do you have a CUDA-capable GPU?
What driver?
What CUDA version?

5

Yes, it’s Nvidia Quadro 5600 GPU, driver 169.04, CUDA 1.1.

Thanks.

6

What is the output of the deviceQuery example from the SDK?

7

Thanks for the tip on the deviceQuery example. I solved the problem by using that information.

Thanks!

8

I ran into the same problem.How did you solve the problem?

Could you explain it in detail?

Thank you!

Same here!!

cufftPlan1d runs fine up to NX=1024, but fails above this size, with:

cufft: ERROR: C:/cygwin/home/cuda0/cuda/sw/gpgpu_rel1.1/cufft/src/plan.cu, line

35

cufft: ERROR: CUFFT_INTERNAL_ERROR

This is with CUDA 1.1, VS2005, XP SP2, 8800 GTS 512.

All of the examples in CUDA-SDK build and run fine.

It’s “just” that I can’t get CUDAFFT to work!

Even this very basic program (InitCUDA source omitted):

int main (int argc, char **argv)

{

	cufftHandle  Plan;

	if(!InitCUDA()) 

	{

  return 0;

	}

	CUDA_SAFE_CALL (cufftPlan1d (&Plan, 4096, CUFFT_C2C, 1));

	return 0;

}

fails with the dreaded CUFFT_INTERNAL_ERROR!

It runs fine with 1024 instead of 4096.

My system has 4 GB of RAM.

Thanks for any help…

Fernando
