HP-UX Workload Manager Toolkits User's Guide

HP-UX WLM Duration Management Toolkit and HP-UX WLM Toolkit for Base SAS Software
Why use DMTK / SASTK with WLM?
Chapter 6106
In Figure 6-2, we have the same three applications—App1, App2, and
App3. This time, however, duration management is used. App3 is started
earlier in the day—with duration management ensuring it still finishes
by 6 am. With duration management in effect, App3 now consumes about
30% of the CPU resources. Consequently, App1 and App2 are able to user
their typical 20% and 50% of the CPU resources.
Figure 6-2 Unrelated applications with duration management
Another example of when DMTK / SASTK is useful is the case when
several related processes run simultaneously. Duration management can
remove spikes in the load by making all the processes complete about the
same time. Each process needs to be in a workload group of its own so
that WLM can manage the durations individually.
