Decentralised and Adaptive workflows

Participants : Christine Morin, Jean-Louis Pazat, Javier Rojas Balderrama, Matthieu Simonin, Cédric Tedeschi, Palakyiem Wallah.

Template workflows

Participants : Christine Morin, Javier Rojas Balderrama, Matthieu Simonin, Cédric Tedeschi.

In the framework of the DALHIS associate team (http://project.inria.fr/dalhis ), we started to combine the high-level template workflow language TIGRES (http://tigres.lbl.gov/home ), developed by our partner team from Lawrence Berkeley National Lab (LBL) with the workflow management system developed in the team [5] . The design of this integration and its benefits have been presented in a workhsop article [24] .

Adaptive Workflows with Chemical Computing

Participants : Javier Rojas Balderrama, Matthieu Simonin, Cédric Tedeschi.

We are currently designing a complete programming model for the management of adaptive workflows, based on an extension of the HOCL language, in particular workflows that may evolve at run time in their shape. An article is under preparation.

Best-effort decentralised workflow execution

Participants : Jean-Louis Pazat, Cédric Tedeschi, Palakyiem Wallah.

We are currently proposing a simple workflow model for workflow execution in platforms with limited computing resources and services. The key idea is to devise a best-effort workflow engine that does not require a strong centralised orchestrator. Such a workflow engine relies on point-to-point cooperation between nodes supporting the execution.
