    Conference report
    Open Access
    In the recent years streaming accelerators like GPUs have been pop-up as an effective step towards parallel computing. The wish-list for these devices span from having a support for thousands of small cores to a nature ...
  • Dynamic transaction coalescing 

    Stipic, Srdjan; Karakostas, Vasileios; Smiljkovic, Vesna; Gajinov, Vladimir; Unsal, Osman Sabri; Cristal Kestelman, Adrián; Valero Cortés, Mateo (Association for Computing Machinery (ACM), 2014)
    Conference report
    Restricted access - publisher's policy
    Prior work in Software Transactional Memory has identified high overheads related to starting and committing transactions that may degrade the application performance. To amortize these overheads, transaction coalescing ...

    Interconnection networks are one of the fundamental components of a supercomputing facility, and one of the most expensive parts. They represent one of the main differences between two supercomputers built from the same ...
  • Peripheral twists for torus topologies with arbitrary aspect ratio 

    Vallejo Gutiérrez, Enrique; Moreto Planas, Miquel; Martínez, Carmen; Beivide Palacio, Julio Ramón (2011)
    Conference report
    Open Access
    A torus is a common topology used in supercomputer networks. Asymmetric Tori suffer from resource usage imbalance, which translates to reduced performance. Twisted Tori employ a twist in the peripheral links of one or more ...
