11. 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.

12. The Ephemeral City : Songs for the Ghost Quarters
Sammanfattning : The towers of the Stockholm skyline twine with radio transmissions, flying out over the city, drifting down through the streets and sinking into the underground telephone system below. Stockholm has buildings that have been there for centuries, but is also full of modern and contemporary architectures, all jostling for their place in parallel collective memory. LÄS MER
13. Laga efter läge : Statsråds föreställningar om styrning i Regeringskansliet
Sammanfattning : This thesis concentrates on two questions: What beliefs do ministers have of appropriate steering in the Swedish core executive Regeringskansliet (RK)? Do they believe that RK is a politically steered organization as it is usually described, or as a throughout political organization, as some political scientists have recently depicted it? RK embraces two institutional subcultures: one non-political with permanent civil servants and firm rules and regulations for work processes, the other one political, where work conditions are more adaptive. Analyses of beliefs that ministers may have, build on information from interviews with 35 ministers in governments from 1991 to 2014. LÄS MER
14. Data Prefetching Techniques Targeting Single and a Network of Processing Nodes
Sammanfattning : This thesis considers two approaches to the design of high-performance computers. In a single processing node with one processor, performance is degraded when requested data is not found in the cache, because it has to be retrieved from slower memory. LÄS MER
15. Spatially Coupled Turbo-Like Codes
Sammanfattning : The focus of this thesis is on proposing and analyzing a powerful class of codes on graphs---with trellis constraints---that can simultaneously approach capacity and achieve very low error floor. In particular, we propose the concept of spatial coupling for turbo-like code (SC-TC) ensembles and investigate the impact of coupling on the performance of these codes. LÄS MER
