Workflow automation for processing plasma fusion simulation data

Abstract

The Center for Plasma Edge Simulation project aims to automate the tedious tasks of monitoring the simulation, archiving and post-processing the output. This paper describes the tasks and requirements, the several components developed within the Kepler workflow system to provide the required functionality and the automated workflow solution. Besides functionality, the focus is on the robust execution of the workflow. A user-level checkpoint/restart model has been developed that allows the workflow to restart, moreover, it also performs operations that failed during the previous run.
