Code generation of array constructs for distributed memory systems
… since it would require a complex combination of MPI, OpenMP, CUDA, OpenCL, etc to achieve high performance even for sequentially simplistic codes. Programs requiring high performance are usually painstakingly written by hand in C/C++ or Fortran using MPI+X to target these machines. This work …

Techniques for communication optimization of parallel programs in an adaptive runtime system
… and distributed memory communication level, e.g. MPI, to create a model known as MPI+X. In this work, we present an alternative approach to improving the performance of modern HPC applications utilizing current generation supercomputer networks. We focus on the combination of several of the …

Towards a deeper understanding of hybrid programming
… model based on the message-passing interface (MPI). Thereby, they potentially do not make optimal use of shared memory resources. The pure message-passing approach---as argued in this work---is not necessarily the best fit to current and future supercomputing architectures. In this thesis, I …
