Algorithms for Data Migration
… thesis is concerned with the problem related to data storage and management. A large storage server consists of several hundreds of disks. To balance the load across disks, the system computes data layouts that are typically adjusted according to the workload. As workloads change over time, the …

Automatic Geometric Data Migration Throughout Views of a Model Fidelity Family
Changes in geometric model parameters are constant throughout the design process. Each group in an organization needs different model information at varying times during the design process. As a result many different models of the same part or assembly arise for the needs and use of each group in …

ADAM : a decentralized parallel computer architecture featuring fast thread and data migration and a uniform hardware abstraction
… is to reduce latency by migrating threads and data, but the overhead of existing implementations has previously made migration an unserviceable solution so far. I present an architecture, implementation, and mechanisms that reduces the overhead of migration to the point where migration is a …

Critical success factors, mechanisms, and information technology project success: a case study of a data migration project in a large South African organisation
… Success Mechanisms was utilised to guide the data collection process. The model was based on three fundamental constructs developed from various sources of literature viz. success criteria, critical success factors, and mechanisms. The study made use of a single case study based on a data …

Towards Improving Endurance and Performance in Flash Storage Clusters
… with a critical goal to optimize performance. Data migration techniques are used to handle wear balancing but they suffer from a huge metadata overhead and extra erasures. To overcome these problems, we propose an endurance-aware write off-loading technique (EWO) for balancing the wear across …

Supporting I/O for Remote Visualization of High-Performance Scientific Simulations
… library that show that our proposed approach to data migration can reduce application turnaround time significantly. We also show that our declustering approaches can reduce the retrieval time for visualization queries on heterogeneous disks, while lessening performance variance across different …

Database engine integration and performance analysis of the BigDAWG polystore system
The BigDAWG polystore database system aims to address workloads dealing with large, heterogeneous datasets. The need for such a system is motivated by an increase in Big Data applications dealing with disparate types of data, from large scale analytics to realtime data streams to text-based …

Efficient storage and retrieval methods for multimedia information
… extensive storage capacity for multimedia data at very economical cost, but the long access latency of tertiary storage devices makes them not attractive for multimedia systems. In this thesis, we present new storage and retrieval methods to handle multimedia data on hierarchical storage …

Optimization of FFT communication on 3-D torus and mesh supercomputer networks
… a new mapping that greatly improves performance. Data migration techniques are then used to alleviate possible link contention associated with the new mappings. Migration techniques are discussed and modeled. It is discovered that specific migration patterns are able to reduce link contention …

Developing, Optimizing and Hosting Data-Driven Web Applications
… challenges in developing, optimizing and hosting data-driven web applications. Data-Driven web applications are usually structured following the standard three-tier architecture with different programming models used at different tiers. This division not only creates an impedance mismatch problem …

Remote sensing for geomorphic and hydrodynamic modeling and process understanding
… sensing. Due to the novelty of remote sensing data, there are still unknowns that need investigation to better understand how these data can be properly applied to our current models and empirical understanding. This dissertation contains three studies that examine how remote sensing, in …
