Toward Dark Silicon in Servers

Energy-efficient Scheduling for Heterogeneous Servers in the Dark Silicon Era

Driven by stringent power and thermal constraints, heterogeneous multi-core processors, such as the ARM big-LITTLE architecture, are becoming increasingly popular. In this thesis, the use of low-power heterogeneous multi-cores as Microservers using web search as a motivational application is addressed. In particular, I propose a new family of scheduling policies for heterogeneous microservers t...

A Perspective on Dark Silicon

The possibilities to increase single core performance has ended due to limited instruction level parallelism and a high penalty when increasing frequency. This prompted designers to move towards multi-core paradigms [1], largely supported by transistor scaling [2]. Scaling down transistor gate length makes it possible to switch them faster at a lower power, as they have a low capacitance. In th...

Toward Integration Dark Matter Revisited

D istributed systems, middleware, and integration are just plain hard. The seemingly intractable difficulties permeating these areas drive our industry to continually seek out easier ways to build such systems. During the past 20 years, we’ve produced myriad toolkits aimed at simplifying distributed programming and integration, including many proprietary or homegrownbased approaches and many ot...

Asynchronous Design Methods for Dark Silicon Chips

The scaling of CMOS technologies continues to enable each two years more and more transistors to the ASIC designers and eventually application users. In theory this would mean that the processing architectures could also exponentially develop in the direction of further many-processor systems scaling. Nevertheless there are significant issues which may disable such scenario with the current (20...
