To create a workflow by using Flow
Flow module initiates a sequence of processing modules. This is the first module added by default when the user creates a workflow inside the g-Platform main window. Whenever the user adds any module, it will automatically adds below the Flow module.
After the Flow module, the user can add other modules to build workflows to suit your objectives.
The workflow can include a number of different tasks by inserting additional Flow modules. The can add a comment to any Flow entry or module within a workflow by pressing F2 key.
Inside the Flow, the user can add as many FLOW modules as they want. Also, whenever there is a second Flow module added within a Flow module and theuser wants to add any other module, it will come up with few options like Modules Inside & Modules Next.
If the user chooses Modules Inside, it will add the next module below the current/selected Flow.
In case the user selected Modules Next, the next module will be added outside the Flow module.
When the user selects the Flow (back ground color changes to BLUE) and double click or press the execute button, it will execute the entire workflow from top to bottom.
In between if there is any workflow with Flow is added and it is not active, it will skip it and move to the next one.
In this above image, if we observe, there is a Flow at the top. Below the Flow, we've added multiple Flow(s). The user can expand or collapse these individual workflows by simply clicking on the + icon right before the Flow.
There are no input data requirements for this module and this tab is disabled.
There are no parameters associated with this module.
Run scripts - this option is used when the user wants to run some special scripts to delay the execution of the workflow or terminate the workflow or to start and stop the cluster nodes etc. This is very useful feature when the user wants to submit/terminate the jobs while the nodes working/not working.
By default, FALSE (Unchecked). If TRUE (Checked). it is possible to use user's scripts for execution any additional commands before and after workflow execution
Script before run - path to ssh file and its name that will be executed before workflow calculation. For example, it can be a script that switch on and switch off remote server nodes (on Cloud).
Script after run - path to ssh file and its name that will be executed before workflow calculation.
Skip - By default, FALSE(Unchecked). This option helps to bypass the module from the workflow.
