    ATLAS 10m
    
    Speakers: Dr Andreu Pacheco Pages (Institut de Física d'Altes Energies - Barcelona (ES)), Rodney Walker (Ludwig Maximilians Universitat (DE))
    
    We just had the ATLAS workflow management meeting with a round table going through our latest projects.
    
    Already mentioned by Tadashi in presentation:
    * Thoughts on metrics: how do we describe if a change in PanDA made things better or worse. Still in early stages of thinking how this could be and the machinery to collect and store metrics.
    * R&Ds: Task requirement predictions through ML and tracking system error codes and messages. System errors should not count towards the user job retries.
    
    * Submitted abstract to WLCG Environmental Sustainability Workshop about job CO2 estimations: https://indico.cern.ch/event/1450885/overview
    
    * Planning to rewrite and modernise the PanDA server API
    * Cleaner code and organization
    * Json
    * Documentation
    * Versioning
    * Data Carousel being implemented in PanDA: Instead of each task submitting independent staging requests, tasks with input on tape will go through a central machinery to make more controlled access. This should optimise and relieve tape systems from unorganised tape staging requests.
