| Cluster (Hosts)
A list of the cluster's computers (hosts) with the status of each – Add (not yet added, clicking it immediately sends the add request), Adding (connection in progress), Added (active), Left (disconnected/crashed) – together with the number of awake/maximum computing processes (slaves) and the relative computing speed compared to the fastest computer in the cluster. Checking several computers and using the Add All button adds several hosts at once.
