SHTns is a high-performance Spherical Harmonic Transform library. It was designed for numerical simulation (fluid flows, mhd, etc.) in spherical geometries, but can be used for any kind of problem involving scalar or vector spherical harmonics. It is very fast, thanks to careful vectorization and runtime tuning. It supports multi-threaded transforms via OpenMP. It features scalar and vector transforms, synthesis and analysis, and flexible truncation and normalization. A Python interface is included.
Ada Util is a collection of utility packages for Ada 2005. Several packages are inspired from Java packages and libraries (Java properties, log4j, listeners, streams). The library provides a logging framework, a serialization/deserialization framework for XML, JSON, CSV, an Ada beans framework, a composition stream framework (raw, files, buffers, pipes, sockets), several concurrency tools (reference counters, counters, pools, fifos, arrays), a REST client framework, and more.
