Energy-efficient computer systems are making increasing use of processors that have multiple core units, DVFS, and virtualization support. However, current system clocks have not been usually designed to cope with the capacity of such mechanisms to decelerate/accelerate the passage of time, which increases the time drifts in the system and produces two adverse side effects. First, a reduction in the...
Many works have reported simulated performance benefits of stream reuse techniques such as batching, chaining, and patching to the scalability of VoD systems. However, the relative contribution of such techniques has been rarely evaluated in practical implementations of scalable VoD servers. In this work, we investigated the efficiency of representative stream reuse techniques on the GloVE system,...
