15.6.1.3.2 Clustering Performance Summary Report

This report is the anchor of the Workload Characterization
application and provides a complete overview of the results
of the clustering process.  You can use this report to make a
quick determination of how well the operation performed and
to better understand how each cluster feature contributed to
the overall performance of the process.  Additionally, the
execution options and operating parameters used in the
process are included to provide a record of the complete
operation.

Sparse clusters are defined as having a population that is less than 0.5% of the total population. In this study, the sparse cluster population limit is 10 cases. _____________________________________________________________________________________


  Figure 15-26.  Clustering Performance Summary report

In the above report, cluster 9 accounts for nearly 92 percent
of all jobs.  The jobs represented by this cluster are the
bulk of the work performed by this LPAR, and any new job
class structure should ensure that these jobs receive
priority in terms of the number of initiators.  Additionally,
clusters 11 & 14 contain significant numbers of jobs and will
need to be considered in any new job class scheme as well.
