libsharp 3.8.2
Channel: guix
Location: gnu/packages/astronomy.scm (gnu packages astronomy)
Home page: https://healpix.sourceforge.io/
Licenses: GPL 2+
Build system: gnu
Synopsis: Efficient spherical harmonic transforms at arbitrary spins
Description:

This package provides a librari for spherical harmonic transforms (SHTs), which evolved from the libpsht library, addressing several of its shortcomings, such as adding MPI support for distributed memory systems and SHTs of fields with arbitrary spin, but also supporting new developments in CPU instruction sets like the Advanced Vector Extensions (AVX) or fused multiply-accumulate (FMA) instructions. The library is implemented in portable C99 and provides an interface that can be easily accessed from other programming languages such as C++, Fortran, Python etc. Generally, libsharp's performance is at least on par with that of its predecessor; however, significant improvements were made to the algorithms for scalar SHTs, which are roughly twice as fast when using the same CPU capabilities.
