Techniques for communication optimization of parallel programs in an adaptive runtime system
… node level, e.g. OpenMP, 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 …

Software topological message aggregation techniques for large-scale parallel systems
High overhead of fine-grained communication is a significant performance bottleneck for many classes of applications written for large scale parallel systems. This thesis explores techniques for reducing this overhead through topological aggregation, in which fine-grained messages are dynamically …
