Reusing cached schedules in an out-of-order processor with in-order issue logic
Modern processors use out-of-order processing logic to achieve high performance in Instructions Per Cycle (IPC) but this logic has a serious impact on the achievable frequency. In order to get better performance out of ...
Multifaceted resource management on virtualized providers
Last decade, providers started using Virtual Machines (VMs) in their datacenters to pack users and their applications. This was a good way to consolidate multiple users in fewer physical nodes while isolating them from ...
Architectural support for high-performing hardware transactional memory systems
Parallel programming presents an efficient solution to exploit future multicore processors. Unfortunately, traditional programming models depend on programmer’s skills for synchronizing concurrent threads, which makes ...
Parallel video decoding
Digital video is a popular technology used in many different applications. The quality of video, expressed in the spatial and temporal resolution, has been increasing continuously in the last years. In order to reduce the ...
Managing dynamic non-uiform cache architectures
Researchers from both academia and industry agree that future CMPs will accommodate large shared on-chip last-level caches. However, the exponential increase in multicore processor cache sizes accompanied by growing on-chip ...
Mstack: a communications stack for mobile ad-hoc networks
Les xarxes mòbils ad-hoc, també conegues com a MANETs, han estat des de fa ja molt temps objectiu d'estudi per part de la comunitat científica. No obstant això, la seva importància dins el món de la indústria és encara ...
GMPLS-OBS interoperability and routing acalability in internet
The popularization of Internet has turned the telecom world upside down over the last two decades. Network operators, vendors and service providers are being challenged to adapt themselves to Internet requirements in a way ...
A Multi-core processor for hard real-time systems
The increasing demand for new functionalities in current and future hard real-time embedded systems, like the ones deployed in automotive and avionics industries, is driving an increment in the performance required in ...
Programming, debugging, profiling and optimizing transactional memory programs
Transactional memory (TM) is a new optimistic synchronization technique which has the potential of making shared memory parallel programming easier compared to locks without giving up from the performance. This thesis ...
Network coding for transport protocols
With the proliferation of smart devices that require Internet connectivity anytime, anywhere, and the recent technological advances that make it possible, current networked systems will have to provide a various range of ...
Proactive software rejuvenation solution for web enviroments on virtualized platforms
The availability of the Information Technologies for everything, from everywhere, at all times is a growing requirement. We use information Technologies from common and social tasks to critical tasks like managing nuclear ...
Load shedding in network monitoring applications
Monitoring and mining real-time network data streams are crucial operations for managing and operating data networks. The information that network operators desire to extract from the network traffic is of different size, ...
Optimizing programming models for massively parallel computers
Since the invention of the transistor, clock frequency increase was the primary method of improving computing performance. As the reach of Moore's law came to an end, however, technology driven performance gains became ...
A prediction-based routing mechanism for optical and IP/MPLS networks
En los últimos años, las nuevas aplicaciones de Internet tales como aplicaciones multimedia, video a demanda, etc, requieren progresivamente mayor capacidad y garantías de calidad de servicio. En ese sentido el modelo de ...
Securing group based peer-to-peer systems
Peer-to-peer applications enable a group of users to create a communications framework from scratch without the need of a central service provider. This is achievable via the aggregation of resources each one of them ...
On the programmability of heterogeneous massively-parallel computing systems
Heterogeneous parallel computing combines general purpose processors with accelerators to efficiently execute both sequential control-intensive and data-parallel phases of applications. Existing programming models for ...
Planificación global en sistemas multiprocesador de tiempo real
Esta tesis afronta el problema de la planificación de sistemas de tiempo real utilizando sistemas multiprocesador con memoria compartida. Según laliteratura este problema es NP-Hard. En las aplicaciones de sistemas de ...
