Workflow Generation with wfGenes

Performing simulation and data analysis on su-percomputers requires using workflow management systems(WMSs). Due to the high diversity of application requirementsthere are currently many different WMSs in use with verydifferent input languages and enactment mechanisms. This hin-ders the reuse of workflows across these WMSs and makes thetransition from one WMS to another difficult. We propose alightweight framework based on a generative approach to makethis affordable for the WMS end user. With a proof-of-conceptimplementation, wfGenes, workflows for different workflowssystems are generated automatically from an abstract workflowdescription. We tested wfGenes for a use case in computationalnanoscience to generate workflows for FireWorks and SimStack. The framework can be readily extended to support further WMSsand to adopt a more standardized workflow description languagefor its input.
