Computer-language based data prefetching techniques
(Universitat Politècnica de Catalunya, 2019-01-25)
Tesi
Accés obertData prefetching has long been used as a technique to improve access times to persistent data. It is based on retrieving data records from persistent storage to main memory before the records are needed. Data prefetching ... -
Compiler and runtime based parallelization & optimization for GPUs
(Universitat Politècnica de Catalunya, 2018-12-13)
Tesi
Accés obertGraphics Processing Units (GPU) have been widely adopted to accelerate the execution of HPC workloads due to their vast computational throughput, ability to execute a large number of threads inside SIMD groups in parallel ... -
Aggressive undervolting of FPGAs : power & reliability trade-offs
(Universitat Politècnica de Catalunya, 2018-11-19)
Tesi
Accés obertIn this work, we evaluate aggressive undervolting, i.e., voltage underscaling below the nominal level to reduce the energy consumption of Field Programmable Gate Arrays (FPGAs). Usually, voltage guardbands are added by ... -
Hardware runtime management for task-based programming models
(Universitat Politècnica de Catalunya, 2018-11-26)
Tesi
Accés obertTask-based programming models allow programmers to express applications as a collection of tasks with dependences. They are simple to use and greatly improve programmability by using software runtimes to exploit task ... -
Orchestration of distributed ingestion and processing of IoT data for fog platforms
(Universitat Politècnica de Catalunya, 2018-11-26)
Tesi
Accés obertIn recent years there has been an extraordinary growth of the Internet of Things (IoT) and its protocols. The increasing diffusion of electronic devices with identification, computing and communication capabilities is ... -
Exploiting asymmetric multi-core systems with flexible system software
(Universitat Politècnica de Catalunya, 2018-11-21)
Tesi
Accés obertAsymmetric multi-cores (AMCs) are a successful architectural solution for both mobile devices and supercomputers. These architectures combine different types of processing cores designed at different performance and power ... -
Bringing cognition to multilayer transport networks
(Universitat Politècnica de Catalunya, 2018-11-09)
Tesi
Accés obertOperator’s transport networks are becoming increasingly more complex due to the large number of network layers needed to support the ever increasing number of new services (e.g., video-on-demand, social media, on-line ... -
Enhancing timing analysis for COTS multicores for safety-related industry : a software approach
(Universitat Politècnica de Catalunya, 2018-11-15)
Tesi
Accés obertArtificial system interaction with the real environment is in general based on the deployment of properly coordinated sensors and actuators, establishing between them a “dynamic control-loop”. The time to close this ... -
Model driven root cause analysis and reliability enhancement for large distributed computing systems
(Universitat Politècnica de Catalunya, 2018-10-15)
Tesi
Accés obertOver last years the number of Big Data, supercomputing, Internet of Things (IoT) or edge systems has snowballed. The core part of many areas and services in academia and business, are large, distributed, and complex IT ... -
Crowdsensing-driven route optimisation algorithms for smart urban mobility
(Universitat Politècnica de Catalunya, 2018-10-22)
Tesi
Accés obertUrban rörlighet anses ofta vara en av de främsta möjliggörarna för en hållbar statsutveckling. Idag skulle det dock kräva ett betydande skifte mot renare och effektivare stadstransporter vilket skulle stödja ökad social ... -
On service optimization in community network micro-clouds
(Universitat Politècnica de Catalunya, 2018-09-21)
Tesi
Accés obertInternet coverage in the world is still weak and local communities are required to come together and build their own network infrastructures. People collaborate for the common goal of accessing the Internet and cloud ... -
Memory systems for high-performance computing: the capacity and reliability implications
(Universitat Politècnica de Catalunya, 2018-07-02)
Tesi
Accés obertMemory systems are signicant contributors to the overall power requirements, energy consumption, and the operational cost of large high-performance computing systems (HPC). Limitations of main memory systems in terms of ...
