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. ### Design Goals - Sparse frequency domain input - Reuse of pre-allocated memory - Support for shifted indexing with centered zero-frequency - Optional parallelization and GPU acceleration - Unified interface for calculations on CPUs and GPUs - Support of Complex-To-Real and Real-To-Complex transforms, where the full hermitian symmetry property is utilized - C++, C and Fortran interfaces ### Interface Design To allow for pre-allocation and reuse of memory, the design is based on two classes: - **Grid**: Provides memory for transforms up to a given size. - **Transform**: Created with information on sparse input data and is associated with a *Grid*. Maximum size is limited by *Grid* dimensions. Internal reference counting to *Grid* objects guarantee a valid state until *Transform* object destruction. A transform can be computed in-place and out-of-place. Addtionally, an internally allocated work buffer can optionally be used for input / output of space domain data. fas: fed500 Comments: Working on packages with rocfft and single precision. Checking on appropriate location for Fortran modules in MPI packages. Ensuring all directories are owned.
