Web是的；使用numpy的fftpack。如果速度不够快，您可以尝试为FFTW-PyFFTW使用python绑定，但是从fftpack到FFTW的加速效果不会那么显著。我真的怀疑是否有必要只针对FFT来加入C++——它们是Python绑定的理想情况。 P>如果你需要速度，那么你想去FFTW，检查项目。 Web,c++,multithreading,C++,Multithreading,在我的Color类中，我有一个私有的静态bool，它确定一个新颜色是否应该对其alpha进行预乘。由于此值仅在创建任何次线程之前读取（并且仅在创建任何次线程之前设置），因此在2个线程上实例2种颜色是否安全 谢谢从多个线程读 …

WebSep 16, 2013 · The best way to get the fastest possible transform in all situations is to use the FFTW object directly, and the easiest way to do that is with the builders functions. In your case: t = pyfftw.builders.fft (a) timeit t () With that I get pyfftw being about 15 times faster than np.fft with a 128 length array. Share. Web我只是想知道如果有人知道是否有可能设置debuger这样F11只对单线程感兴趣？我有两个运行atm的线程，但我只对其中的一个感兴趣。因此，我不希望屏幕继续向上跳转，以显示第一个线程在做什么。编号喜欢设置它，以便它只显示第二个线程正在做什么。 任何指针，将不胜感激，谢谢。

The critical variable there is nthreads - the number of threads used during plan computation. Both thread-safety and functional correctness depend on the value of this variable. eq2 raid mountsWebOperating FFTW in multithreaded mode is supported. The core interface is provided by a unified class, pyfftw.FFTW. This core interface can be accessed directly, or through a series of helper functions, provided by the pyfftw.builders module.
