CUFFT_INTERNAL_ERROR --> Maybe it's a bug. I suspect that is a serious BUG in cufft

Accelerated Computing CUDA CUDA Programming and Performance

In this application , I make a cudaErrorLaunchFailure happened intendedly.

The problem is that if cudaErrorLaunchFailure happened, this application will crash at cufftDestroy(g_plan).

And, if you do not call cufftDestroy(g_plan), this application will also crash when it’s over.

When it crashed, error message will be printed as follow:

(CUDA 1.1)

cufft: ERROR: C:/cygwin/home/cuda0/cuda/sw/gpgpu_rel1.1/cufft/src/plan.cu, line 35

cufft: ERROR: CUFFT_INTERNAL_ERROR

(CUDA 2.0 Beta2)

cufft: ERROR: D:/Bld/rel/gpgpu/toolkit/r2.0/cufft/src/plan.cu, line 35

Possible that you have hit the tip of an iceberg!

It’s exactly my problem, too!

I’m sure that if you try limiting the number of elements in cufftplan to 1024 (cufft 1d) it works, which hints about a memory allocation problem.

Initially I also suspected the 4GB of RAM (in association with XP-32), but I tried with and without /3GB in boot.ini and had the same problem; since the OS memory mapping is quite different in the two situations, I tend to exclude it has something to do with having 4GB.

Please keep me posted if you discover something.
