Aggressive undervolting of FPGAs : power & reliability trade-offs
In 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
Task-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
In 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
Asymmetric 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
Operator’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
Artificial 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
Over 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
Urban 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
Internet 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
Memory 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 ...
Elastic phone : towards detecting and mitigating computation and energy inefficiencies in mobile apps
Mobile devices have become ubiquitous and their ever evolving capabilities are bringing them closer to personal computers. Nonetheless, due to their mobility and small size factor constraints, they still present many ...
Programming models for mobile environments
For the last decade, mobile devices have grown in popularity and became the best-selling computing devices. Despite their high capabilities for user interactions and network connectivity, the computing power of mobile ...
Contributions to routing scalability and QoS assurance in cloud data transport networks based on the recursive internetwork architecture
With an increasing number of devices and heterogeneous distributed applications, it is becoming evident that service delivered by the current Internet fall short to supply the actual Quality of Service (QoS) requirements ...
Development and certification of mixed-criticality embedded systems based on probabilistic timing analysis
An increasing variety of emerging systems relentlessly replaces or augments the functionality of mechanical subsystems with embedded electronics. For quantity, complexity, and use, the safety of such subsystems is an ...
High-level compiler analysis for OpenMP
Nowadays, applications from dissimilar domains, such as high-performance computing and high-integrity systems, require levels of performance that can only be achieved by means of sophisticated heterogeneous architectures. ...
Towards cognitive in-operation network planning
Next-generation internet services such as live TV and video on demand require high bandwidth and ultra-low latency. The ever-increasing volume, dynamicity and stringent requirements of these services’ demands are generating ...
A time-predictable many-core processor design for critical real-time embedded systems
Critical Real-Time Embedded Systems (CRTES) are in charge of controlling fundamental parts of embedded system, e.g. energy harvesting solar panels in satellites, steering and breaking in cars, or flight management systems ...
E-EON : Energy-Efficient and Optimized Networks for Hadoop
Energy efficiency and performance improvements have been two of the major concerns of current Data Centers. With the advent of Big Data, more information is generated year after year, and even the most aggressive predictions ...
Reducing redundancy of real time computer graphics in mobile systems
The goal of this thesis is to propose novel and effective techniques to eliminate redundant computations that waste energy and are performed in real-time computer graphics applications, with special focus on mobile GPU ...
Low-power architectures for automatic speech recognition
Automatic Speech Recognition (ASR) is one of the most important applications in the area of cognitive computing. Fast and accurate ASR is emerging as a key application for mobile and wearable devices. These devices, such ...
