  • Energy optimising methodologies on heterogeneous data centres 

    Nishtala, Rajiv (Universitat Politècnica de Catalunya, 2017-07-10)
    Doctoral thesis
    Open Access
    In 2013, U.S. data centres accounted for 2.2% of the country's total electricity consumption, a figure that is projected to increase rapidly over the next decade. A significant proportion of power consumed within a data ...
  • Energy optimizing methodologies on heterogeneous data centers 

    Nishtala, Rajiv; Carpenter, Paul; Petrucci, Vinicius; Martorell Bofill, Xavier (Barcelona Supercomputing Center, 2017-05-04)
    Conference report
    Open Access
    In 2013, U.S. data centers accounted for 2.2% of the country’s total electricity consumption, a figure that is projected to increase rapidly over the next decade. Many important work-loads are interactive, and they demand ...

  • RePP-C: runtime estimation of performance-power with workload consolidation in CMPs 

    Nishtala, Rajiv; Martorell Bofill, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Conference report
    Open Access
    Configuration of hardware knobs in multicore environments for meeting performance-power demands constitutes a desirable feature in modern data centers. At the same time, high energy efficiency (performance per watt) requires ...
  • REPP-H: runtime estimation of power and performance on heterogeneous data centers 

    Nishtala, Rajiv; Martorell Bofill, Xavier; Petrucci, Vinicius; Mossé, Daniel (2016)
    Conference report
    Open Access
    Modern data centers increasingly demand improved performance with minimal power consumption. Managing the power and performance requirements of the applications is challenging because these data centers, incidentally or ...
  • Runtime estimation of performance–power in CMPs under QoS constraints 

    Nishtala, Rajiv; Martorell Bofill, Xavier; Carpenter, Paul (Barcelona Supercomputing Center, 2015-05-05)
    Conference report
    Open Access
    One of the main challenges in data center systems is operating under certain Quality of Service (QoS) while minimizing power consumption. Increasingly, data centers are exploring and adopting heterogeneous server architectures ...
