      abstract     = {In this talk, we provide an introduction to the Maestro
                      project.This project was started in September 2018 involving
                      the following partners:Appentra, CEA, Cray, CSCS, ECMWF,
                      Forschungszentrum Juelich, Seagate.The goal is to develop
                      and demonstrate a new middleware that aims at addressingtwo
                      key shortcomings observed for today's supercomputing
                      solutions.First, available solutions typically lack data
                      awareness as they are optimisedfor filling processing
                      pipelines, not for managing data.Furthermore, available
                      solutions lack memory awareness, i.e. available middlewaredo
                      not have information about available memory (or storage)
                      hardware and thusare not able to make data transport
                      decisions.Maestro applies a co-design approach for designing
                      a solution addressing these challenges.The co-design
                      applications, in particular, include data-intensive
                      applications likethe weather prediction workflow from
                      ECMWF.In this case, simulations of the IFS model produce
                      huge amounts of data that are consumedby other applications,
                      which generate products for ECMWF's products member states
                      and customers.This matches well Maestro's concept of
                      providing a pool of data objects, wheredata producers give
                      objects to the pool and data consumers take objects from the
                      pool.Using suitable metadata, the Maestro middleware can
                      manage storing and transport of data objectstaking the
                      hardware architecture into account, on which the
                      applications are being executed.We will conclude this talk
                      with an outlook on the work of the Maestro project.},
