ab: Summary: In this chapter we present the new capabilities of QosCosGrid
    (QCG) middleware for advanced job and resource management in the grid
    environment. By connecting many computing clusters together, QosCosGrid
    offers easy-to-use mapping, execution and monitoring capabilities for a
    variety of complex computations, such as parameter sweep, workflows,
    MPI or hybrid MPI-OpenMP as well as multiscale simulations. Thanks to
    QosCosGrid, large-scale programming models written in Fortran, C, C++
    or Java can be automatically distributed over a network of computing
    resources with guaranteed Quality of Service ‒ for example guaranteed
    startup time of a job. Consequently, applications can be run at
    specified periods with reduced execution time and waiting times. This
    enables more complex problem instances to be addressed. In order to
    prove the usefulness of the new functionality of QosCosGrid a detailed
    description of the system along with a real use case scenario from the
    quantum chemistry science domain will be presented in this chapter.
