In this tutorial, we will guide you step-by-step through the web portals: the Studio, the Scheduler, the Resource Manager and the Automation Dashboard portals.
1 Your first single task job
The easiest way to build your workflow is the online Studio portal which is
The main components are:
2 Your first multi-task job
Click on the Workflow Studio button to open the studio interface.
Click on the File->Close button to show the workflow list.
Click on Create to create a second workflow, and Open it.
Edit the workflow name and enter Parallel tasks.
Drag and drop a few tasks.
You can click on the Layout button to reorganize the layout.
3 Your first replicated tasks job
Create a 4th workflow and name it Replicate job.
Drag & drop the Replicate control from the Controls menu.
Click on the replicate script and set the number of runs to 10.
Execute the workflow.
Click on Resource Manager to open its interface. Execute the replicate job again, and watch how ProActive nodes are used to execute the tasks.
4 Your first multi-node job
Create a 5th workflow and name it Multinode job.
Drag & drop the Multi-Node Task from the basic-examples menu.
Click on the task, then on Multi-Node Execution.
Set the Number of Nodes to 4.
In the Topology list, choose single host.
Execute the job and watch on the Resource Manager how multiple ProActive Nodes are used by the task.
5 Import and Export your workflow
Workflows are represented in XML format, such as:
6 Customize your task
Tasks can be defined using various script languages. When a task is drag & dropped
from the Tasks menu,
it contains a default code such as print ‘Hello World’. Let’s see how we can edit
the provided code.
Create a new workflow and call it Script job, create a Groovy task and click on it.
On the left panel, in the Task Implementation tab, you can edit the script content. You can use the button to open an editor with syntax highlighting.
The Scheduler Portal allows to see task results and errors (when they don’t appear in the task logs). Create a new workflow and call it Result job, create a Groovy task and replace the script code by the following:
Jython, Scalaw, …
Create a new workflow and open it. Drag and drop the corresponding script languages Tasks. Execute the workflow and observe that all tasks are executed successfully.
7 Job lifecycle
The user has some control over the job execution. Let’s illustrate the possibilities
by an example.
Open the Replicate job and submit it. Then open the scheduler interface.
Right-click on the job and select Pause.
8 ProActive Catalog
From the studio interface, users can publish their workflows into the ProActive
Catalog. Users can also import existing workflows to modify or execute them.
Multiple revisions of the same workflows are handled to follow the workflow
Let’s modify the Multinode Job. Click on the task and rename it to myTask.
From the Catalog menu, click on Publish current Workflow to the Catalog.
9 ProActive Automation Dashboard
ProActive Automation Dashboard gathers views for business people.
First of all, from the Workflow Automation view, select the Himmelblau_Function workflow in the auto-ml-optimization bucket and submit it 3 times.

Select one of the monitoring rules on the right panel.
Check/modify parameters (workflow to trigger,..) from the popup before clicking on the Activate button.
To modify a rule: Right click on a rule and Edit.
This view centralizes all notifications triggered by jobs. Let’s trigger a validation notification!
Go to Workflow Automation view, select the notification-tools bucket and click on the Web_Validation workflow and Submit.
Go to the Notifications view, select the Validation requests sub view under the Notifications tab.
You can validate/unvalidate/ignore your validation notification by clicking on one of these .
