Max VMs Optional The maximum number of virtual machines to run the application This is used only for COMPSs applications e Min VMs Optional The minimum number of virtual machines to run the application This is used only for COMPSs applications Besides that information each application also contains a list of arguments To add a new one hit the green button on top of the argument list 43 Each argument will be optional if specified or mandatory otherwise and it is defined by a name an optional default value and an optional prefix When launching the application a value for each argument will be requested and passed to the command line in the order they appear on the list The way the actual command will be constructed is e For COMPSs applications runcompss executable prefix argument e For non COMPSs applications executable prefix argument Once all the information is provided hitting the Save button will add a new application to the system Finally applications can be edited by hitting the pencil button 2 on their right in the applications list Job Management Once an application has been created it is possible to run jobs in the infrastructure To do that in the main view of the dashboard Figure 1 go to Jobs New and select the type of job This action will show a job submission dialog like the one depicted in Figure 3 To create a new job select the application to launch insert the desired valu
