cufftPlanMany

Hi all.
I use cuda v 4 and GT 1030.
In my program I try to calculate 1d fft with overlapping.
For this I use cufftplanmany.
And it’s work correct for 1024 fft size and 100 batch, but if i want calculate more than 2 batch with fft size more than 1024(2048 example),
I got results only for 2 batches …
Why?
Please help me.

Another worlds, I need calculate 100 batches with overlapping 2046 for fft size 2048.

CUDA 4.0 is extremely old. Any reason why you can’t use a newer version?
