Prints basic statistics about the network topology which will result from a given system.

$ spinner-topology-stats -h
usage: spinner-topology-stats [-h] [--version] (--num-boards N | --triads W H)
                              [--transformation {shear,slice}]
                              [--uncrinkle-direction {columns,rows}]
                              [--folds X Y]

Print basic topological statistics for a specified configuration of boards.

optional arguments:
  -h, --help            show this help message and exit
  --version, -V         show program's version number and exit

machine topology dimensions:
  --num-boards N, -n N  build the 'squarest' system with this many boards
  --triads W H, -t W H  build a system with the specified number of triads of
                        boards in each dimension (yielding 3*W*H boards)

topology folding options:
  --transformation {shear,slice}, -T {shear,slice}
                        the transformation function to use from hexagonal
                        torus to rectangular Cartesian grid (selected
                        automatically if omitted)
  --uncrinkle-direction {columns,rows}
                        direction in which to uncrinkle the hexagonal mesh to
                        form a regular grid (default: rows)
  --folds X Y, -F X Y   the number of pieces to fold into in each dimension
                        (default: (2, 2)) ignored if --transformation is not

Finding sytstem dimensions

The most common use-case for spinner-topology-stats is determining the network dimensions of a given system of N boards.

For example, want to know about a 120-board system?

$ spinner-topology-stats -n 120
Topology Statistics

| Measurement        | Value  | Unit  |
| ------------------ | ------ | ----- |
| Network dimensions | 96x60  | chips |
| Board array        | 8x5    | triad |
| Number of boards   | 120    |       |
| Number of cables   | 360    |       |
| Number of chips    | 5760   |       |
| Number of cores    | 103680 |       |

In this example, the network of SpiNNaker chips in this system will be 96x60 and the system is made up of 8x5 triads.
