System monitoring with lo2s: Power and runtime impact of c-state transitions
2018 IEEE International Parallel and Distributed Processing …, 2018•ieeexplore.ieee.org
In this paper, we present improvements to the low-overhead performance monitoring tool
lo2s. We combine a detailed recording of system events with information from a high-
resolution power measurement, to record the scheduling of applications and C-state
transitions. These sub-millisecond transitions are difficult to observe with traditional
approaches. Our methodology provides us with insights into the behavior of the system
before, during, and after C-state transitions of processors cores.
