Does automatic muliprocessor scaling affect 1D FFT?

[bobertrg270]

Hello,

I am computing 1D forward FFT's using DftiComputeForward and am not seeing a change in performance when I run on mulit-core machines. I have tried setting OMP_NUM_THREADS=numProcs. Can someone please tell me what I need to do to enable mulitprocessor scaling?

Thank you,
Bob

I actually found the answer to my question. There is no parralelization when computing a single fft at a time. However, multiple FFT's can be automatically done in parallel.
