FINUFFT v.2.3.0 is out! Check out the new Performance page!

[DiamonDinoia]

FINUFFT v2.3.0 is out. Thanks for all the feedback on the release candidate! Some minor issues were signaled and are now fixed.

FINUFFT v2.3.0 is the first version that uses explicit SIMD vectorization to improve performance and it also supports DUCC0 FFT.

We added a new Performance page to the documentation to monitor FINUFFT performance across releases so that slowdowns can be caught early and hopefully avoided. It also includes some benchmarks showing the difference in performance between DUCC0 and FFTW. We encourage the users to validate our results (scripts and code to generate plots are present in the repository) and participate in the relevant discussions to share FINUFFT uses, but also performance issues and bugs.

This release includes many new features since 2.2.0. The main ones are:

• major performance improvements in CPU spread/interpolation through manual SIMD vectorization
• performance improvements for the GPU library
• switchable FFT: either FFTW3 or DUCC0 (where the latter exploits sparse block structure for speed in 2D and 3D)
• modernized Python wrapping
• revamped CMake build
• many bugfixes, improved testing and benchmarking, new documentation...
• See CHANGELOG for the full list.
