This step creates a resolution IV screening design,
which computes effects involving either one or two options, while
assuming that no significant higher order effects exist (in the
interests of space we have not included the statistical details of
computing and interpreting screening designs, which are described in
Wu []). The final screening design examines only 32
configurations of the 16,384 total configurations. Note that
benchmarking the entire configuration space takes over 48 CPU hours,
while benchmarking the screening design takes less than 6 minutes.
