  • Instruction replication for clustered microarchitectures 

    Aleta Ortega, Alexandre; Codina Viñas, Josep M.; González Colás, Antonio María; David, Kaeli (Institute of Electrical and Electronics Engineers (IEEE), 2003)
    Text en actes de congrés
    Accés obert
    This work presents a new compilation technique that uses instruction replication in order to reduce the number of communications executed on a clustered microarchitecture. For such architectures, the need to communicate ...
  • A structural encoding technique for the synthesis of asynchronous circuits 

    Carmona Vargas, Josep; Cortadella Fortuny, Jordi; Pastor Llorens, Enric (2000-12)
    Report de recerca
    Accés obert
    This paper presents a method for the automatic synthesis of asynchronous circuits from Petri net specifications. The method is based on a structural encoding of the system in such a way that a circuit implementation is ...
  • Analysis and optimization of engines for dynamically typed languages 

    Dot Artigas, Gem; Martínez, Alejandro; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Dynamically typed programming languages have become very popular in the recent years. These languages ease the task of the programmer but introduce significant overheads since assumptions about the types of variables have ...
  • MASkIt: soft error rate estimation for combinatorial circuits 

    Anglada Sánchez, Martí; Canal Corretger, Ramon; Aragon, Juan Luis; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Integrated circuits are getting increasingly vulnerable to soft errors; as a consequence, soft error rate (SER) estimation has become an important and very challenging goal. In this work, a novel approach for SER estimation ...
  • Towards incentive-compatible pricing for bandwidth reservation in community network clouds 

    Khan, Muhammad Amin; Vilaça, Xavier; Rodrigues, Luís; Freitag, Fèlix (Springer, 2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Community network clouds provide for applications of local interest deployed within community networks through collaborative efforts to provision cloud infrastructures. They complement the traditional large-scale public ...
  • On the sustainability of community clouds in guifi.net 

    Baig Viñas, Roger; Freitag, Fèlix; Navarro Moldes, Leandro (Springer, 2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The Internet and cloud services are key enablers for participation in society. The need for Internet access in areas underserved by commercial telecom operators has often been a motivation to develop community networks. Many ...
  • Toward sustainable data centers: a comprehensive energy management strategy 

    Guitart Fernández, Jordi (2016-06-28)
    Article
    Accés restringit per política de l'editorial
    Data centers are major contributors to the emission of carbon dioxide to the atmosphere, and this contribution is expected to increase in the following years. This has encouraged the development of techniques to reduce the ...
  • Shared resource aware scheduling on power-constrained tiled many-core processors 

    Jha, Sudhanshu Shekhar; Heirman, Wim; Falcón Samper, Ayose Jesus; Tubella Murgadas, Jordi; González Colás, Antonio María; Eeckhout, Lieven (2017-02-01)
    Article
    Accés restringit per política de l'editorial
    Power management through dynamic core, cache and frequency adaptation is becoming a necessity in today’s power-constrained many-core environments. Unfortunately, as core count grows, the complexity of both the adaptation ...
  • Energy-efficient Internet of Things monitoring with low-capacity devices 

    Carbajales, Rodrigo J.; Zennaro, Marco; Pietrosemoli, Ermanno; Freitag, Fèlix (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Text en actes de congrés
    Accés obert
    The Internet of Things (IoT) allows users to gather data from the physical environment. While sensors in public spaces are already widely used, users are reluctant to deploy sensors for shared data at their homes. The ...
  • Hubbub-scale: towards reliable elastic scaling under multi-tenancy 

    Rameshan, Navaneeth; Ying, Liu; Navarro Moldes, Leandro; Vlassov, Vladimir (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Elastic resource provisioning is used to guarantee service level objective (SLO) with reduced cost in a Cloud platform. However, performance interference in the hosting platform introduces uncertainty in the performance ...
