Atlas is a ECMWF framework for parallel data-structures supporting unstructured grids and function spaces.
Atlas is predominantly C++ code, with main features available to Fortran codes through a F2003 interface.
It requires some flavour of Unix (such as Linux). It is known to run on a number of systems, some of which are directly supported by ECMWF.
Greek Mythology
Atlas was the primordial Titan who held up the celestial spheres. He is also the titan of astronomy and navigation.

PS -- Atlas is not an acronym, so it should not be capitalized.
Applications using Atlas
