In this simple program I have attached, it appears that the results are not the same. Is this some byproduct of the way I am calculating the abs() function for the std::complex vs. the cuComplex value?
I plotted this and it seems like the CUFFT bars are scaled somewhat more than the FFTWF bars across the 50 rows.
Any idea whats goign on there?
