      abstract     = {Accelerators arrived to HPC when the power bill for
                      achieving Flop performance with traditional, homogeneous
                      systems became too expensive. By attaching graphic cards (or
                      many-core processors) to general purpose processors, certain
                      application kernels could be sped up at a much lower
                      Watt/flop rate.In 2011 the DEEP project recognised the
                      advantages that heterogeneous processors offered to HPC, but
                      raised the question whether the host-device approach chosen
                      until then for their integration was the most beneficial.
                      The proposed alternative was based on the construction of a
                      cluster of autonomous accelerators, so-called "Booster". The
                      "Cluster" and the "Booster" in DEEP are nothing else than
                      two compute modules with different hardware designs,
                      addressing each different application requirements. By
                      connecting each other with a high-speed network and
                      providing a full software stack that supports them jointly,
                      the resulting "Modular Supercomputer" behaves as a single
                      machine in which users can freely choose resources from any
                      of the compute modules.I will present the architecture and
                      concepts realised in the DEEP and DEEP-ER projects, some of
                      which are going into production this year within JSC's
                      JURECA system. A glimpse of the further developments planed
                      within the just started DEEP-EST project, will also be
                      presented.},
