In my code, somewhere, I generate a gpuArray matrix with a size of 331x331x331x32, (single float) and I want to get an fftn from the array in a for loop. I have a 24GB TITAN RTX GPU, and before getting each fftn, I have 10 GB free on the GPU. But, when I run the code, it can calculate it without problem, but for the second loop, it returns:
An invalid FFT plan was used on the GPU.
If I pause the code and rerun the fftn, it works fine, but again, I get the error for the next loop, and the same story goes for the next loops!
I also tried the reset(gpuDevice(1)) before each for loop and noticed when I have this pice before each iteration, I will get the error, and if I run it twice, the problem will be solved! Would you please explain to me why I have this problem?
