The code for computing the weights was developed with SPARCompiler Pascal 3.0 and cross-compiled to C with p2c, version 1.20. The actual compilation took place with the cc compiler (again using the -O3 flag) on a SPARCstation 20 with 64 MB main memory and SunOS 5.3 operating system.
On this machine we computed the optimal weights for the facility distributions from the first stage with facilities (see Section 3.2).
Computation times were obtained by the UNIX time command. Figure 6 shows these computation times for Stage 2.
Figure - for N = 16, 25, 36, 49 and - for N = 64, 81, 100, whereas the extremal fundamental systems of Reimer and Sündermann  differ from equal weights by about - for N = 16, 25, 36, 49. Moreover, our weights are closer to equal weights than the weights from . All of our weights are positive except for some isolated cases.
