Recent architectures provide the possibility to modify the uncore
frequency (L3 cache, memory controllers, ...). Similar to DVFS
techniques, it is handled by the Uncore Frequency Scaling (UFS). In
this talk, we will first study the default behavior of UFS and present
the impact of uncore frequency on power, energy and performance for
different application profile. Then we will present how uncore
frequency can be used as a leverage to improve application
