Replace write_arrays with init_arrays
...
This allows each model to initialise their arrays with a parallel
approach, which yields the first touch required for good performance
on NUMA architectures.

Switch data from 1.0, 2.0 and 3.0 to 0.1, 0.2, and 0.3 resp.
...
Using integers for maths gets unstable past 38 interations even
in double precision. Using the original values/10 is safe up to
the default 100 iterations.
