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
given

Making Machine-Readable Physical-Position-to-Chip-Coordinate Mappings¶
A CSV format mapping between physical cabinet, frame and board position to the
SpiNNaker network coordinates of each Ethernet connected chip can be produced
with the spinner-ethernet-chips command:
$ spinner-ethernet-chips -n 3
cabinet,frame,board,x,y
0,0,0,0,0
0,0,2,4,8
0,0,1,8,4
For a complementary visual mapping from physical board positions to SpiNNaker chip coordinates, see the spinner-wiring-diagram command. For the inverse mapping see spinner-machine-map.
