Resum
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 co-scheduled with. We propose a new hardware accounting mechanism to improve the accuracy when measuring the CPU utilization in CMPs and compare it with the previous accounting mechanisms. Our results show that currently known mechanisms could lead to a 12% average error when it...
