A question about the example 'FFT Ocean Simulation'.

Accelerated Computing CUDA CUDA Programming and Performance

Hello,

When I ran the CUDA sample code ‘FFT Ocean Simulation’ on my GPU, I found in the task manager that this program only uses one core…

I want to know that what’s the cause for this and how can I change this. Thanks. (!)

Only one CPU core? That’s because it’s mainly running on the GPU.

Hi Simon,

I know the program is mainly running on the GPU:-)

But if you check the oceanFFT.exe in the task manager, it’s affined to only one core of the CPU, that’s weird.
