French-US workshop on grid workflows


The workshop will be held on March 23rd and 24th in Sophia Antipolis (area of Nice, France). It will start on the 23rd at 10:30 and finish on the 24th at 16:30.


The meeting will be held in the Polytech' School building (“Les templiers”), in room 424 (council meeting room). Travel instructions and maps can be found here.



The idea of the workshop is to identify what complementarities and overlap our teams have, what are each group strengths and weaknesses, and how this could be used in the future to have a fruitful collaboration. To allocate time to discussions, talks are scheduled with short presentations (15') and long discussions (25') on purpose.


I think we have complementary skills in designing the different layers needed to assemble a complete grid workflow environment, from abstract workflows representation to tasks scheduling:

  • Abstract workflow languages (languages, expressiveness, control and data flows)

    GWENDIA, A data-driven workflow language for grids based on array programming principles

  • Concrete workflow generation (executable workflows production and languages, meta-workflows, just-in-time production)
  • Workflow execution environment
    Tristan (CREATIS)
    A review of operational nightmares and related dreams of grid workflows (preliminary slides)
  • Workflow scheduling (workflow schedulers and scheduling strategies)
    Frédéric Desprez, Frédéric Suter (LIP)
    An Overview of Parallel Task Graph and Multi-Workflow Scheduling Algorithms
  • Resource allocation and tasks scheduling (tasks management)
    Miron (UW), CONDOR

These are 6 talks (15 minutes presentation + 25 minutes discussion = 40 minutes per talk → less than 5h). Each speaker should address a list of questions (to be determined) to help identifying challenges, limitations and what achievement is targeted. We have about 3h left for general discussions (complementarities, expectations, cross-challenges, etc). On the second day we could elaborate on possible interaction and collaboration organization.

French-US collaboration opportunities

  1. There are some modalities for proposing joint NSF-ANR projects (ANR is the French counter-part of NSF). See this document (strangely enough, the document is half-french, half-english).
  2. The PUF (Partner University Fund) set up by the French embassy in the US and the FACE (French American Cultural Exchange) funds research and education partnerships (up to 80000 USD a year, up to 3 years). See PUF.
  3. Chateaubriand traineeship Funding for US PhD students (or young researchers) spending 3 to 10 months in France.
