The developed and tested part of the scalable benchmark code, the
Pythagorean triples core, has been applied to the platform system of a scalable number of processors. The measurement has been performed on the system cluster consisting of 16 Pentium CPUs. The number of nodes of selected subclusters of an equivalent or a different performance of CPUs is scaled by the factor of 2. The core has been running in different conditions (homogeneous subcluster, heterogeneous subcluster, computationally free nodes and/or occupied nodes, etc.). A group of four measurements of the scalable number of processors has been selected and displayed in four characteristic blocks of the elapsed time Windows comparable with those of the previous paper. The characteristic exponential curves fit well to the measured points under the normal conditions of task run. The maximum deviations of the two exponential parameters in all presented cases do not exceed 5 percent.
