Performance Evaluation of Blocking and Non-Blocking Concurrent Queues on GPUs
… GPU environment. We implement both <em>blocking</em> and <em>non-blocking</em> approaches and compare their performance and behavior using both micro-benchmark and real-world application. We provide a complete evaluation and analysis of our implementations on an AMD Radeon R7 GPU. Our …

Precursors to atmospheric blocking events
Atmospheric blocking disturbs synoptic-scale features from their normal eastward progression, causing extreme weather conditions for the duration of the blocking event. Blocking precursors, as indicators of meridional flow preceding the onset of strong Atlantic blocking episodes, have been …

Designing robust railroad blocking plans
… may be grouped together to form a block. The blocking problem consists of choosing the set of blocks to be built at each terminal (the blocking plan) and assigning each commodity to a series of blocks that will take it from origin to destination. It is one of the most important problems in …

Precursors to atmospheric blocking events
Atmospheric blocking events disturb synoptic-scale features from their normal eastward progression, causing anomalous weather conditions for the duration of the blocking event. The essence of blocking can be captured by variation of potential temperature ([theta]trop) on the dynamically-defined …

Reduction of blocking artifacts using side information
… suffer from annoying discontinuities, called blocking artifacts. Prior research shows that incorporating systems that reduce blocking artifacts into codecs is useful because visual quality is improved. Existing methods reduce blocking artifacts by applying various post-processing techniques to …

Non-Blocking Data Structures Handling Multiple Changes Atomically
Here, we propose a new approach to design non-blocking algorithms that can apply multiple changes to a shared data structure atomically using Compare&Swap (CAS) instructions. We applied our approach to two data structures, doubly-linked lists and Patricia tries. In our implementations, only update …

t-blocking sets and semiovals in Witt designs
… of this thesis is to characterize all 't'-blocking sets (see definition 3.1) and all semiovals (see definition 4.2) in the Witt designs up to the frequency vectors. In chapter 2 we obtain some results which correct some mistakes in [7, 8]. We also improve the results in [9]. In chapter 3 we …

Macroscopic Coupling Conditions with Partial Blocking for Highway Ramps
We consider the Lighthill-Whitman-Richards traffic model on a network consisting of a highway with an off ramp, connected by a junction. We compare the known coupling conditions for the evolution of traffic at the junction and suggest a novel improvement to the existing conditions. That is, we …

Design and development of blocking approaches for record linkage
… solutions that address existing issues among blocking approaches used for record linkage.<br/><br/>A thorough explanation of blocking and record linkage is provided so as to better introduce the reader to these concepts. An extensive literature study is also provided to detail many existing …

Scale and stability analysis of selected atmospheric blocking events
… six year climatology of mid latitude atmospheric blocking events, during the period 1999-2004, is presented based on the scale and stability analysis, using the NCEP/NCAR re-analysis data. A total of 278 blocking events over the Northern as well as the Southern Hemispheres are analyzed. It is …

A semi-blocking checkpoint protocol to minimize checkpoint overhead
… bandwidth. In this thesis, we introduce the semi-blocking checkpoint/restart protocol to hide the checkpoint overhead by overlapping global checkpoint with applications. To further analyze the benefits of using semi-blocking checkpoint protocol in case of failures, we extend Daly’s model and show …

Scalable non-blocking Krylov solvers for extreme-scale computing
… at scale. Many Krylov solvers require frequent blocking allreduce collective operations that can limit performance at scale due to the increasing cost of this collective as the node count increases and the cost of synchronizing all processes. This thesis investigates non-blocking Krylov solver …
