The Fast Fourier Transform (FFT) is an efficient algorithm for computing the Discrete Fourier Transform (DFT). This Intellectual Property core was designed to offer very fast transform times while ...

Unfortunately, the arithmetic complexity of using floating-point poses implementation issues and consequently fixed-point FFT implementations have historically been more common in embedded ...

kokkos-fft implements local interfaces between Kokkos and de facto standard FFT libraries, including FFTW, cufft, hipfft (rocfft), and oneMKL. "Local" means not using MPI, or running within a single ...

The geometry is meshed with a regular voxel structure (uniform grid). Some geometries/problems are not suited for voxel structures (inefficient meshing). For such cases, PyPEEC can be very slow and ...
