    • Measuring TCP bandwidth on top of a Gigabit and Myrinet network 

      Costa Prats, Juan José; Bueno Hedo, Javier; Martorell Bofill, Xavier; Cortés, Toni (2009)
      Research report
      Open Access
      In this article we measure the bandwidth achieved by the TCP protocol on top of a Gigabit and Myrinet network. We have created a synthetic benchmark, consisting on a server and a client that both produce and consume data, ...
    • Platform-agnostic steal-time measurement in a guest operating system 

      Verdú Mulà, Javier; Costa Prats, Juan José; Otero Calviño, Beatriz; Rodríguez Luna, Eva; Pajuelo González, Manuel Alejandro; Canal Corretger, Ramon (2018-10)
      Research report
      Open Access
      Steal time is a key performance metric for applications executed in a virtualized environment. Steal time measures the amount of time the processor is preempted by code outside the virtualized environment. This, in turn, ...
    • Running OpenMP application efficiently on an everything-shared SDSM
