Adaptive execution environments for application servers
El creixement experimentat tant per la web com per Internet en els últims anys ha potenciat l'introducció de servidors d'aplicacions dins de la majoria d'entorns d'execució distribuits. El servidors d'aplicacions web porten ...
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 ...
Self-tuned parallel runtimes: a case of study for OpenMP
In recent years parallel computing has become ubiquitous. Lead by the spread of commodity multicore processors, parallel programming is not anymore an obscure discipline only mastered by a few.<br/>Unfortunately, the amount ...
Analysis and architectural support for parallel stateful packet processing
The evolution of network services is closely related to the network technology trend. Originally network nodes forwarded packets from a source to a destination in the network by executing lightweight packet processing, or ...
A Dynamic Validation Infrastructure for Interoperable Grid Services
Los encargados de recursos Grid pueden autorizar el acceso a sus elementos de cómputo por medio de procedimientos bien establecidos para los clientes, regularmente a través del uso de credenciales criptográficas que en su ...
Affordable kilo-instruction processors
Diversos motius expliquen l'estancament en el que es troba el desenvolupament del processador tradicional dissenyat per maximitzar el rendiment d'un únic fil d'execució. Per una banda, técniques agressives com la supersegmentacó ...
Predicated execution and register windows for out-of-order processors
ISA extensions are a very powerful approach to implement new hardware techniques that require or benefit from compiler support: decisions made at compile time can be complemented at runtime, achieving a synergistic effect ...
Improving web server efficiency on commodity hardware
El ràpid creixement de la Web requereix una gran quantitat de recursos computacionals que han de ser utilitzats eficientment. Avui en dia, els servidors basats en hardware estendard son les plataformes preferides per ...
Aplicación de la simulación en tiempo real para mejorar la calidad de servicio del middleware
La utilización de aplicaciones de diferente naturaleza dentro de un mismo entorno, entorno heterogéneo, se está extendiendo gracias a la incorporación de técnicas de virtualización a los servidores. Compartir un servidor ...
Improving cache Behavior in CMP architectures throug cache partitioning techniques
The evolution of microprocessor design in the last few decades has changed significantly, moving from simple inorder single core architectures to superscalar and vector architectures in order to extract the maximum available ...
Runahead threads
Los temas de investigación sobre multithreading han ganado mucho interés en la arquitectura de computadores con la aparición de procesadores multihilo y multinucleo. Los procesadores SMT (Simultaneous Multithreading) son ...
Formal mission specification and execution mechanisms for unmanned aircraft systems
Unmanned Aircraft Systems (UAS) are rapidly gaining attention due to the increasing potential of their applications in the civil domain. UAS can provide great value performing environmental applications, during emergency ...
Spectral analysis of executions of computer programs and its applications on performance analysis
This work is motivated by the growing intricacy of high performance computing infrastructures. For example, supercomputer MareNostrum (installed in 2005 at BSC) has 10240 processors and currently there are machines with ...
Exploring coordinated software and hardware support for hardware resource allocation
Multithreaded processors are now common in the industry as they offer high performance at a low cost. Traditionally, in such processors, the assignation of hardware resources between the multiple threads is done implicitly, ...
Heterogeneity-awareness in multithreaded multicore processors
During the last decades, Computer Architecture has experienced a great series of revolutionary changes. The increasing transistor count on a single chip has led to some of the main milestones in the field, from the release ...
GRID superscalar: a programming model for the Grid
Durant els darrers anys el Grid ha sorgit com una nova plataforma per la computació distribuïda. La tecnologia Gris permet unir diferents recursos de diferents dominis administratius i formar un superordinador virtual amb ...
"Virtual malleability" applied to MPI jobs to improve their execution in a multiprogrammed environment"
This work focuses on scheduling of MPI jobs when executing in shared-memory multiprocessors (SMPs). <br/>The objective was to obtain the best performance in response time in multiprogrammed multiprocessors systems using ...
