System administrators can produce more starting conïfigurations by multiplying
the values taken from some existing configuration by the same number,
or by combining 2 configurations into a new one. [[UBC derived configuration examples]] shows 2
examples of such configurations, derived from existing examples.
== Scaling configurations ==
Multiplying all the confguration numbers by a number greater than 1
produces a configuration for more “heavy” load or applications (see
[[UBC derived configuration examples#2A|example 2A]]). Multiplying by positive numbers less than 1
produces “lighter” configuration. Configurations produced by multiplying an
existing configuration by a number greater than 1 will be consistent if the
original configuration was consistent.
'''Caution''': lighter configurations produced by multiplying some configuration
by a number less than 1 may happen to be inconsistent (see [[UBC consistency check]]
for more details about configuration consistency).
== Intermediate configurations ==
It is also possible to produce intermediate configurations between the
given two, combining the numbers with coefficients:
<math>
config_{new} = \alpha \cdot config_1 + (1-\alpha) \cdot config_2,
</math>
where <math>0<\alpha<1</math>. Example labelled “0.5A+0.5B” (see [[UBC derived configuration examples]]) is such an intermediate configuration with <math>\alpha=</math>½.
Intermediate configurations produced by this rule will be consistent if the
original configurations were consistent.
'''Caution''': configurations produced by summing configurations with arbitrary
coefficients (not giving 1 in sum or not all positive) may produce inconsistent
configurations.
