Execution Groups provide a way to partition nodes into different logical domains. Execution Groups more specifically allow the specification of which Jobs are allowed to run on which Nodes.
Execution Groups allow jobs to be restricted to certain nodes. An example would be restricting a bash Job to those Nodes labeled with the "Unix" Execution Group.
A Job does not require an Execution Group to run on a Node. However, if a node contains the Execution Group "Unix" for example, then a Job without any Execution Groups will not run on that node.
Open your web browser and go to http://localhost:8080/cerbergrid then click on Execution Groups and click Create Execution Group, input a name then save and done.
Clicking Execution Groups again will show you your newly created Execution Group.
