It's the CheckpointIO format. It can write either binary or ASCII files
and is similar to the xdr/a format that libmesh uses to write meshes in
serial. Only thing it can't really do is restart from N files on M procs,
but that shouldn't affect your use case.

Yes, that's how it should work. You can use one of the Partitioner classes
that comes with libmesh, or partition the mesh yourself in some
application-specific way.
