Agenda - Main components: Director, Actor, Port, Relation - Workflow building area - Different workflow types - Actor related details - Concept of composite actor - Java API 4 HPC/GRID EUFORIA FP7-INFRASTRUCTURES , Grant

How can I build workflow? Kepler allows you to build workflows using standard elements: - Workflow - Director - Actor - Port - Relation EUFORIA FP7-INFRASTRUCTURES , Grant

Accessing workflow - Workflow allows to compose data flow between elements - Elements can be Dragged and Dropped into Workflow's area - After workflow is ready it can be started two ways: directly from the GUI from the command line EUFORIA FP7-INFRASTRUCTURES , Grant

Accessing workflow EUFORIA FP7-INFRASTRUCTURES , Grant

Accessing Actors and Directors - Available elements can be accessed through the component's browser - Elements can be Dragged and Dropped into Workflow's area - You can search for elements if you don't know the exact name of the component - You can add your own components into library EUFORIA FP7-INFRASTRUCTURES , Grant

Accessing Actors and Directors EUFORIA FP7-INFRASTRUCTURES , Grant

Accessing Supplementary Components - Components that bind all elements together are accessible from toolbar - Ports, relations, can be Dragged and Dropped into Workflow's area - You can easily Start/Stop workflow directly from the GUI using toolbar icons EUFORIA FP7-INFRASTRUCTURES , Grant

Main components EUFORIA FP7-INFRASTRUCTURES , Grant

Directors Directors are responsible for the orchestration of the workflow. Directors can provide various means of execution: - CT Director (Continuous Time) - DDF Director (Dynamic Data flow) - SDF Director (Sequential Data flow) - PN Director (Process Network) - parallel executions EUFORIA FP7-INFRASTRUCTURES , Grant

Actors Actors perform actions basing on input ports and parameters EUFORIA FP7-INFRASTRUCTURES , Grant

Actors - You can use already existing actors that are available within Kepler - You can import actors from the other sources into Kepler - You can develop your own actors and add them to the Kepler EUFORIA FP7-INFRASTRUCTURES , Grant

Concept of composite actor - Composite actors allow to encapsulate workflows - Composite actors can be copy-pasted between workflows - Composite actors can be exported as components EUFORIA FP7-INFRASTRUCTURES , Grant

Concept of composite actor EUFORIA FP7-INFRASTRUCTURES , Grant

Java API 4 HPC/GRID Developed within EUFORIA project - One of the goals of the project is to provide users with convenient way of accessing HPC/GRID infrastructures using Kepler orchestration tool - Java API 4 HPC/GRID is based on vine:toolkit EUFORIA FP7-INFRASTRUCTURES , Grant

What is Java API 4 HPC/GRID EUFORIA FP7-INFRASTRUCTURES , Grant

What Java API 4 HPC/GRID provides Java API 4 HPC/GRID provides: - set of actors that extends Kepler with HPC access - set of actors that extends Kepler with GRID access - already existing workflows that can be modified - set of composite actors for faster workflow building EUFORIA FP7-INFRASTRUCTURES , Grant

Thank you for your attention EUFORIA FP7-INFRASTRUCTURES , Grant
