After the HPVM front-end client applet is launched, the main window is displayed. The user performs nearly all client operations by interacting with components in the main window. The main window consists of four major components:
The menu bar contains menus for `Authentication', `Cluster Monitoring', and `Job Submission'. The `Authentication' menu contains options that allow the user to `Log On' to the HPVM cluster, or to `Exit' the applet. The `Cluster Monitoring' menu contains options that allow the user to `List Cluster Hosts' which displays a list of all hosts in the HPVM cluster along with load information for each host, or to invoke the `Real Time Cluster Monitor' window which displays updating graphs containing load information for each host. Finally, the `Job Submission' menu contains options that allow the user to `Submit Jobs' for execution on the cluster, `Kill Jobs' that are running on the cluster, `List the Job Queue' to display a list of all running and queued batch jobs on the cluster, or `List Finished Jobs' to display a list of all batch jobs which have recently finished running on the cluster.
The text window in the main window displays output from various commands. For example, the `List Cluster Hosts' command and the `List Job Queue' command display their output in the text window. Additionally, most other commands display messages in the text area indicating whether the command completed successfully or failed.
The host panel and queue panel in the main window display a list of hosts in the HPVM cluster and a list of queues in the HPVM cluster respectively. When the user double-clicks on a host listed in the host list, a dialog box is displayed listing information about the host. This information includes the host status, utilization metrics, and various counts of free memory on the host. Similarly, when the user double-clicks on a queue listed in the queue list, a dialog box is displayed listing information about the queue. This information includes the queue name and description, the number of batch jobs in various states in the queue, and a list of hosts to which the queue dispatches jobs.
