  • ITCA: Inter-Task Conflict-Aware CPU accounting for CMP 

    Luque, Carlos; Moreto Planas, Miquel; Cazorla Almeida, Francisco Javier; Gioiosa, Roberto; Valero Cortés, Mateo (2010)
    Conference report
    Open Access
    Chip-MultiProcessors (CMP) introduce complexities when accounting CPU utilization to processes because the progress done by a process during an interval of time highly depends on the activity of the other processes it is ...
