Build the Flow

Now that we have a flow description, we need to build the flow with vovbuild. Before we do that, however, we recommend that you use the GUI to monitor what is happening, as you have learned in the user tutorial. Also, in case you still have the flow generated in the user tutorial, you should tell FlowTracer to forget it.
% vovconsole &
% vovforget -elements System:nodes
% vovbuild 
....   # 4 dots, one per job.

Building the flow is different from running it. The jobs in the flow may take hours or days to execute, but building the flow is normally a rather quick step.
