This is the second paper in a series describing a numerical implementation
of the conformal Einstein equation. This paper deals with the technical det
ails of the numerical code used to perform numerical time evolutions from a
'minimal' set of data.
We outline the numerical construction of a complete set of data for our equ
ations from a minimal set of data. The second- and the fourth-order discret
izations, which are used for the construction of the complete data set and
for the numerical integration of the time evolution equations, are describe
d and their efficiencies are compared. By using the fourth-order scheme we
reduce our computer resource requirements-with respect to memory as well as
computation time-by at least two orders of magnitude as compared to the se
cond-order scheme.
