What is rocFFT?
|
|
********************************************************************
|
|
|
|
The rocFFT library implements the discrete Fast Fourier Transform (FFT) in HIP for GPU devices.
|
|
It provides a fast and accurate platform for calculating discrete FFTs.
|
|
The source code can be found at `<https://github.com/ROCm/rocm-libraries/tree/develop/projects/rocfft>`_.
|
|
|
|
rocFFT supports the following features:
|
|
|
|
* Half (``FP16``), single, and double precision floating point formats
|
|
* 1D, 2D, and 3D transforms
|
|
* Computation of transforms in batches
|
|
* Real and complex FFTs
|
|
* Arbitrary lengths, with optimizations for combinations of powers of 2, 3, 5, 7, 11, 13, and 17
|
|
|
|
rocFFT also provides experimental support for:
|
|
|
|
* Distributing transforms across multiple GPU devices in a single process
|
|
* Distributing transforms across multiple MPI (Message Passing Interface) processes
|
|
|
|
