in the context of per-cpu data.  The library offers ABI headers to interface
with the kernel and various utilities such as per-cpu counters.")

It can also compare (@dfn{diff}) binaries with graphs and extract information

facilitate the exchange between codes and solvers.

The persistent data storage is based upon HDF format (like CGNS, a standard
developed by Boeing and NASA in the area of Computational Fluid Dynamic).

MED also provides structures to hold data on meshes and fields.  These
structures are exchanged between solvers, hide the communication level (CORBA
or MPI), and offer persistence (read/write in .med files).

The main benefit of a common exchange format is reduced complexity of code
coupling.  It also allows sharing such high level functionalities as
computation of nodal connectivity of sub-elements (faces and edges),
arithmetic operations on fields, entity location functionalities, and
interpolation toolkit.")

supports both the original X11 protocol for communicating with the driver, and
the new alternative non-X protocol.  Programs that choose to use the X11
protocol, are automatically compatible with either the free spacenavd driver
or the official 3dxserv, as if they were using the magellan SDK.

Also, libspnav provides a magellan API wrapper on top of the new API.  So, any
applications that were using the magellan library, can switch to libspnav
without any changes.  And programmers that are familiar with the magellan API
can continue using it with a free library without the restrictions of the
official SDK.")
