Broadcast-oriented wireless network-on-chip : fundamentals and feasibility
Recent years have seen the emergence and ubiquitous adoption of Chip Multiprocessors (CMPs), which rely on the coordinated operation of multiple execution units or cores. Successive CMP generations integrate a larger number ...
In-operation planning in flexgrid optical core networks
New generation applications, such as cloud computing or video distribution, can run in a telecom cloud infrastructure where the datacenters (DCs) of telecom operators are integrated in their networks thus, increasing ...
Orchestrating datacenters and networks to facilitate the telecom cloud
In the Internet of services, information technology (IT) infrastructure providers play a critical role in making the services accessible to end-users. IT infrastructure providers host platforms and services in their ...
Per-task energy metering and accounting in the multicore era
Chip multi-core processors (CMPs) are the preferred processing platform across different domains such as data centers, real-time systems and mobile devices. In all those domains, energy is arguably the most expensive ...
Improving the performance and energy-efficiency of virtual memory
Virtual memory improves programmer productivity, enhances process security, and increases memory utilization. However, virtual memory requires an address translation from the virtual to the physical address space on every ...
Multicore architecture prototyping on reconfigurable devices
In the the last decades several performance walls were hit. The memory wall and the power wall are limiting the performance scaling of digital microprocessors. Homogeneous multicores rely on thread-level parallelism, which ...
Scalable community detection for social networks
Many applications can be modeled intuitively as graphs, where nodes represent the entities and the edges the relationships between them. This way, we are able to better understand them and how they interact. One particularity ...
Circuit designs for increasing reliability and reducing energy
Computing technology has witnessed an inimitable progress in the last decades which is the result of CMOS technology scaling commensurate with Moore's law. Transistor feature sizes have shrunk to half at each generation, ...
Memory architectures for exaflop computing systems
Most computing systems are heavily dependent on their main memories, as their primary storage, or as an intermediate cache for slower storage systems (HDDs). The capacity of memory systems, as well as their performance, ...
An approach to pervasive monitoring in dynamic learning contexts : data sensing, communication support and awareness provision
It is within the capabilities of current technology to support the emerging learning paradigms. These paradigms suggest that today’s learning activities and environments are pervas ive and require a higher level of dynamism ...
Specialization and reconfiguration of lightweight mobile processors for data-parallel applications
The worldwide utilization of mobile devices makes the segment of low power mobile processors leading in the entire computer industry. Customers demand low-cost, high-performance and energy-efficient mobile devices, which ...
Identifying and combating cyber-threats in the field of online banking
This thesis has been carried out in the industrial environment external to the University, as an industrial PhD. The results of this PhD have been tested, validated, and implemented in the production environment of Caixabank ...
Extending the applicability of deterministic multithreading
With the increased number of cores on a single processor chip, an application can achieve good performance if it splits the execution into multiple threads that run on multiple cores at the same time. To synchronize threads, ...
Code-Centric Domain Isolation : a hardware/software co-design for efficient program isolation
Current software systems contain a multitude of software components: from simple libraries to complex plugins and services. System security and resiliency depends on being able to isolate individual components onto separate ...
Macro- and microscopic analysis of the internet economy from network measurements
The growth of the Internet impacts multiple areas of the world economy, and it has become a permanent part of the economic landscape both at the macro- and at microeconomic level. On-line traffic and information are currently ...
Incentives for sharing heterogeneous resources in distributed systems : a participatory approach
Contributory and volunteer computing ecosystems built around a community of participants need, like any other common-pool resources, an adaptive governance mechanism to guarantee the sustainability of the ecosystem. ...
Parallel algorithms for fluid and rigid body interaction
This thesis is based on the implementation of a computational system to numerically simulate the interaction between a fluid and an arbitrary number of rigid bodies. This implementation was performed in a distributed ...
Hardware thread scheduling algorithms for single-ISA asymmetric CMPs
Through the past several decades, based on the Moore's law, the semiconductor industry was doubling the number of transistors on the single chip roughly every eighteen months. For a long time this continuous increase in ...
Semantic resource management and interoperability between distributed computing platforms
Distributed Computing is the paradigm where the application execution is distributed across different computers connected by a communication network. Distributed Computing platforms have evolved very fast during the las ...
MPI layer techniques to improve network energy efficiency
Interconnection networks represent the backbone of large-scale parallel systems. In order to build ultra-scale supercomputers larger interconnection networks are being designed and deployed. As compute nodes become more ...
