Don't Race the Memory Bus: Taming the GC Leadfoot

Hussein, Ahmed; Hosking, Antony; Payer, Mathias; Vick, Christopher A.


Dynamic voltage and frequency scaling (DVFS) is ubiquitous on mobile devices as a mechanism for saving energy. Reducing the clock frequency of a processor allows a corresponding reduction in power consumption, as does turning off idle cores. Garbage collection is a canonical example of the sort of memory-bound workload that best responds to such scaling. Here, we explore the impact of frequency scaling for garbage collection in a real mobile device running Android's Dalvik virtual machine,...[Show more]
