SpFFT - A 3D FFT library for sparse frequency domain data written
|
|
in C++ with support for MPI, OpenMP, CUDA and ROCm.
|
|
|
|
Inspired by the need of some computational material science
|
|
applications with spherical cutoff data in frequency domain, SpFFT
|
|
provides Fast Fourier Transformations of sparse frequency domain data.
|
|
For distributed computations with MPI, slab decomposition in space
|
|
domain and pencil decomposition in frequency domain (sparse data
|
|
within a pencil / column must be on one rank) is used.
|
|
|
|
|
|
By default the package is compiled with single-precision float-point
|
|
operations and a sequential version. If you want to change it use the
|
|
following environment variable options:
|
|
- DP=yes, use double-precision.
|
|
- OMP=yes, use openmp.
|
|
|
|
Options that requires extra packages:
|
|
- MPI=yes, use MPI (requires a MPI implementation either mpich or
|
|
openmpi).
|
|
- CUDA=yes, requires CUDA Toolkit
