Archetype implementation

Several implementations (program skeletons and code libraries) exist for the mesh archetype, including:

• Fortran M (1D, 2D, 3D, and 3D without a host process).
• Fortran plus NX (2D and 2D without a host process).

In general, the user-level specifications of all implementations are the same. Where they differ, we describe here the Fortran M 3D implementation. (Fortran M [2, 1] is a Fortran variant available via anonymous FTP from Argonne National Labs.)
