10 Modifying Example Configurations for Compute Nodes Edit source

This section contains detailed information about the Compute Node parts of the input model. For example input models, see Chapter 9, Example Configurations. For general descriptions of the input model, see Section 6.14, “Networks”.

Usually, the example models provide most of the data that is required to create a valid input model. However, before you start to deploy, you may want to customize an input model using the following information about Compute Nodes.
