## Engine Option Window

Figure 8

You can use Engine Option Window, shown in figure, to pick a host profile to use when there are multiple host profiles for a computer or if there are any parallel host profiles. When there is a single serial host profile or no host profiles, the window is not activated when VisIt launches a compute engine. The window's primary purpose is to select a host profile and set some parallel options such as the number of processors. This window is provided as a convenience so host profiles do not have to be modified each time you want to launch a parallel engine is run with a different number of processors.

The Engine Option Window has a list of host profiles from which to choose. The active profile for the host is selected by default though the another can be profile used instead. Once a host profile is selected, the parallel options such as the number of processors/nodes, processor count, can be changed to fine-tune how the compute engine is launched. After making any changes, click the window's OK button to launch the compute engine. Clicking the Cancel button prevents the compute engine from being launched.
