1. Advances in Task-Based Parallel Programming for Distributed Memory Architectures
Sammanfattning : It has become common knowledge that parallel programming is needed for scientific applications, particularly for running large scale simulations. Different programming models are introduced for simplifying parallel programming, while enabling an application to use the full computational capacity of the hardware. LÄS MER
2. Dynamic Traffic Control in Multiservice Networks - Applications of Decision Models
Sammanfattning : In this thesis, we develop and examine decision models intended for traffic engineering analysis of multiservice networks. Two important issues are addressed, namely call admission and routing control in multiservice broadband networks, and overload control in distributed-memory systems. LÄS MER
3. Efficient Memory Access and Synchronization in NoC-based Many-core Processors
Sammanfattning : In NoC-based many-core processors, memory subsystem and synchronization mechanism are always the two important design aspects, since mining parallelism and pursuing higher performance require not only optimized memory management but also efficient synchronization mechanism. Therefore, we are motivated to research on efficient memory access and synchronization in three topics, namely, efficient on-chip memory organization, fair shared memory access, and efficient many-core synchronization.

4. Parallel Algorithms and Library Software for the Generalized Eigenvalue Problem on Distributed Memory Computer Systems
Sammanfattning : We present and discuss algorithms and library software for solving the generalized non-symmetric eigenvalue problem (GNEP) on high performance computing (HPC) platforms with distributed memory. Such problems occur frequently in computational science and engineering, and our contributions make it possible to solve GNEPs fast and accurate in parallel using state-of-the-art HPC systems.

5. Design of Energy-Efficient High-Performance ASIP-DSP Platforms
Sammanfattning : In the last ten years, limited clock frequency scaling and increasing power density has shifted IC design focus towards parallelism, heterogeneity and energy efficiency. Improving energy efficiency is by no means simple and it calls for a reevaluation of old design choices in processor architecture, and perhaps more importantly, development of new programming methodologies that exploit the features of modern architectures.
