SpFFT 1.0.0

SpFFT 1.0.0 Release Notes

This is a new major release, introducing new functionalities.
It is fully backward compatible to previous release, but includes extensions to the API.

Major Changes

• Support for externally allocated memory for space domain data including in-place and out-of-place transforms
• Optional asynchronous computation when using GPUs
• Simplified / direct transform handle creation if no resource reuse through grid handles is required

Minor Changes

• Added CMake option to allow explicit selection of library providing a FFTW3 implementation
• Updated ROCm build to use installed CMake config files
• SpFFT CMake config file generated upon installation is now fully relocatable for static builds as well
