  • Interpolation
  • Configuration of parallel IO in YAC
  • Polygon clipping in YAC
  • Sphere Partitioning Algorithm

The YAC core library contains all functionallity required for generating weights and doing basic exchanges using them.

It has a low-level C and Fortran interface. The C header file (yac_core.h) is generated automatically during the building process.

Additional information

Interpolation

YAC provides extensive interpolation capabilities. A description can be found here.

Configuration of parallel IO in YAC

YAC accesses weight and grid files in parallel. The user can provide hints to YAC in form of multiple environment variables, which are evalutated during runtime.

Polygon clipping in YAC

Some information on the implementation of polygon clipping algorithm in YAC can be found here.

Sphere Partitioning Algorithm

The Sphere Partitioning Algorithm is used in YAC for efficiently accessing data defined on the surface of a sphere. A basic description can be found here.
