Simulator input panels and sample output

---

This section contains the primary simulator input panels and sample output panels.

Select workload pattern

When you start the simulator, Figure 9-3 appears with the application type and workload pattern default to online shopping. You specify your project name, select your application type and workload pattern, and characterize your workload.
