  • DReAM: An approach to estimate per-Task DRAM energy in multicore systems 

    Liu, Qixiao; Moreto Planas, Miquel; Abella, Jaume; Cazorla Almeida, Francisco Javier; Valero Cortés, Mateo (2016-12)
    Article
    Open Access
    Accurate per-task energy estimation in multicore systems would allow performing per-task energy-aware task scheduling and energy-aware billing in data centers, among other applications. Per-task energy estimation is ...
  • DReAM: Per-task DRAM energy metering in multicore systems 

    Liu, Qixiao; Moreto Planas, Miquel; Abella Ferrer, Jaume; Cazorla Almeida, Francisco Javier; Valero Cortés, Mateo (Springer, 2014)
    Conference report
    Open Access
    Interaction across applications in DRAM memory impacts its energy consumption. This paper makes the case for accurate per-task DRAM energy metering in multicores, which opens new paths to energy/performance optimizations, ...
  • Per-task energy accounting in computing systems 

    Liu, Qixiao; Jiménez, Víctor; Moreto Planas, Miquel; Abella, Jaume; Cazorla, Francisco; Valero Cortés, Mateo (2013)
    External research report
    Open Access
    We present for the first time the concept of per-task energy accounting (PTEA) and relate it to per-task energy metering (PTEM). We show the benefits of supporting both in future computing systems. Using the shared last-level ...
  • Per-task energy metering and accounting in the multicore era 

    Liu, Qixiao (Universitat Politècnica de Catalunya, 2016-05-26)
    Doctoral thesis
    Open Access
    Chip multi-core processors (CMPs) are the preferred processing platform across different domains such as data centers, real-time systems and mobile devices. In all those domains, energy is arguably the most expensive ...
  • Per-task energy metering and accounting in the multicore era 

    Liu, Qixiao; Moreto Planas, Miquel; Abell, Jaume; Cazorla Almeida, Francisco Javier; Valero Cortés, Mateo (Barcelona Supercomputing Center, 2015-05-05)
    Conference report
    Open Access
    Energy has become arguably the most expensive resource in a computing system. As multi-core processors are the preferred processing platform across different computing domains, measuring the energy usage draws vast attention. ...
  • SEDEA: A sensible approach to account DRAM energy in multicore systems 

    Liu, Qixiao; Moreto Planas, Miquel; Abella, Jaume; Cazorla, Francisco; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Conference report
    Open Access
    As the energy cost in todays computing systems keeps increasing, measuring the energy becomes crucial in many scenarios. For instance, due to the fact that the operational cost of datacenters largely depends on the energy ...
  • Sensible energy accounting with abstract metering for multicore systems
