How modes misc set of parallel tasks

I have a network configuration project where we need to configure a set of network nodes. A set would consist of two to 10 individual nodes. The kinds of nodes configured would vary greatly from configuration order to configuration order. All of the nodes except the first can be configured in parallel. The entire configuration is finished when all the nodes are configured. The workflow for each node looks approximately like this:


Can anyone suggest what the top level workflow would look like for the set of configurations?

I hope my topic is appropriate for this forum.
