4、根据2生成的随机数作为输入,调用oneMKL API计算二维Real to complex FFT。 解决方法:参考最新版oneMKL工具中的DftiComputeForward( ) 函数,实现利用oneMKL API计算二维Real to complex FFT。 图4 调用DftiSetValue函数进行二维FFT 5、结果正确性验证,对3和4计算的二维FFT输出数据进行全数据比对(允许适当精度误差...
调用oneMKL API 计算两维Real to complex FFT 结果正确性验证 平均性能数据比对,输出FFT参考代码平均运行时间和oneMKL FFT平均运行时间 fft2d(二维傅里叶变换)介绍: 代码实现: 一、用OneMKL生成2048*2048个单精度随机数: VSLStreamStatePtrstream;vslNewStream(&stream,VSL_BRNG_MT19937,1);vsRngUniform(VSL_RN...
I use complex-to-complex transforms because I actually need two real-to-real transforms, backward and forward.everything else in the code is O(n) so the FFTs are the bottleneck. I was hoping for experience users or Intel engineers to give me the long an...
