I wander if someone can help me to setup an hardware configuration for evaluation of the GPU computing in my problem.
My need is to make plenty of Raw data as 2x8192 reals to 8192 complex FFT. By plenty I mean that currently I get 10kHz data that I try to save on disk and make the FFT afterwards. My field of interest is radioastronomy time signal.
So my questions are
- is a GPU FFT (as CUDA provided) can help to perform the FFT in paralell ?
- which minimal hardware should I take to test : GeForce GTX 480 ? or Telsa, which motherboard? do I need a graphic baoard for display and an other one for computing ?
- I am using Linux Ubuntu 10.04, is-it a suatable linux distrib. is this context?
Thanks in advance for any comments and advises.
