Hello
I have a NVIDIA 2000 GPU. It has 192 CUDA cores and 1 Gb memory. GB GDDR5
I am trying to calculate fft by GPU using pyfft.
I am able to calculate the fft only upto the array with maximum of 4096 x 4096.
But as soon after I increase the array size, it gives an error message saying:
pycuda._driver.MemoryError: cuMemAlloc failed: out of memory
Can anyone please tell me if this error means that my GPU is not sufficient to
calculate this array? Or is it my computer's memory? Or a programming error?
What is the maximum array size you can achieve with GPU?
Is there any information of how else can I calculate the huge arrays?
Thank you very much in advance for the help and sorry if it is too preliminary
question.
Jayanth
