FFTs and external threading

I am using Windows threading to compute multiple FFTs simultaneously. I have been sharing the FFTSpec across the threads. I am wondering if this could cause a problem or impede performance? Should each thread maintain its own FFTSpec(s)?

I currently have the built-in threading disabled. I get better performance this way, since there is less competition for the processing cores. The platform is WinXP64, 2xQuad 2.6GHz, with IPP 5.3.2.073, em64t.

Hi Dave,

You can share FFTSpec between threads while FFT order is the same.

Vladimir
