  • A quantitative assessment of thread-level speculation techniques 

    Marcuello Pascual, Pedro; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 2000)
    Conference report
    Open Access
    Speculative thread-level parallelism has been recently proposed as an alternative source of parallelism that can boost the performance for applications where independent threads are hard to find. Several schemes to exploit ...
  • Fg-STP: fine-grain single thread partitioning on multicores 

    Ranjan, Rakesh; Latorre Salinas, Fernando; Marcuello Pascual, Pedro; González Colás, Antonio María (IEEE Press. Institute of Electrical and Electronics Engineers, 2011)
    Conference report
    Restricted access - publisher's policy
    Power and complexity issues have led the microprocessor industry to shift to Chip Multiprocessors in order to be able to better utilize the additional transistors ensured by Moore's law. While parallel programs are going ...
  • P-slice based efficient speculative multithreading 

    Ranjan, Rakesh; Marcuello Pascual, Pedro; Latorre Salinas, Fernando; González Colás, Antonio María (IEEE Computer Society Publications, 2009-12-16)
    Conference report
    Open Access
    Microprocessor industry has recently shifted towards multi-core to take advantage of the ever increasing number of transistors provided by the new technologies. Unfortunately, the multi-core approach does not allow single ...
  • Rendering elimination: early discard of redundant tiles in the graphics pipeline 

    Anglada Sánchez, Martí; de Lucas Casamayor, Enrique; Parcerisa Bundó, Joan Manuel; Aragón, Juan Luis; Marcuello Pascual, Pedro; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Restricted access - publisher's policy
    GPUs are one of the most energy-consuming components for real-time rendering applications, since a large number of fragment shading computations and memory accesses are involved. Main memory bandwidth is especially taxing ...
  • Speculative multithreaded processors 

    Marcuello Pascual, Pedro (Universitat Politècnica de Catalunya, 2003-07-22)
    Doctoral thesis
    Open Access
    En esta tesis se estudia el modelo de ejecución de los procesadores multithreaded especulativos así como los requisitos necesarios para su implementación. El modelo de ejecución se basa en la inserción de instrucciones de ...
  • Thread-spawning schemes for speculative multithreading 

    Marcuello Pascual, Pedro; González Colás, Antonio María (IEEE Computer Society, 2002)
    Conference report
    Open Access
    Speculative multithreading has been recently proposed to boost performance by means of exploiting thread-level parallelism in applications difficult to parallelize. The performance of these processors heavily depends on ...
  • Ultra-low power render based collision detection for CPU/GPU systems 

    Lucas Casamayor, Enrique de; Marcuello Pascual, Pedro; Parcerisa Bundó, Joan Manuel; González Colás, Antonio María (Association for Computing Machinery (ACM), 2015)
    Conference report
    Restricted access - publisher's policy
    Smartphones have become powerful computing systems able to carry out complex tasks, such as web browsing, image processing and gaming, among others. Graphics animation applications such as 3D games represent a large ...
  • Value prediction for speculative multithreaded architectures 

    Marcuello Pascual, Pedro; Tubella Murgadas, Jordi; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 1999)
    Conference report
    Open Access
    The speculative multithreading paradigm (speculative thread-level parallelism) is based on the concurrent execution of control-speculative threads. The efficiency of microarchitectures that adopt this paradigm strongly ...
  • Visibility rendering order: Improving energy efficiency on mobile GPUs through frame coherence 

    Lucas Casamayor, Enrique de; Marcuello Pascual, Pedro; Parcerisa Bundó, Joan Manuel; González Colás, Antonio María (2019-02-01)
    Article
    Open Access
    During real-time graphics rendering, objects are processed by the GPU in the order they are submitted by the CPU, and occluded surfaces are often processed even though they will end up not being part of the final image, ...
