Reducing energy consumption in data center of cloud computing

[ankurparekh65]

Hello All ,

I m doing masters in computer applications form Gujarat .. As a part of curriculum we need to write thesis and my topic is Reducing energy consumption in cloud computing . Due to the hardware dependency we cannot suggest the future implementations . But we all know that computer is made up of chips so we need to do to reduce the energy consumption in chips ? Is there any formula for less energy consumption chips or computer ?

Waiting for the reply

You could try with concept of putting cpu's into low power modes (Cx) states when system load is low.

Simple intro into topic:
**broken link removed**

This Intel paper should give you good overlook and information source as it's describing exactly what you want to do.
"Power and Thermal Management in the Intel® Core TM"

Other architectures are using similar technologies so its great starting point for ideas.

And if you are looking for more low level options (including algorithms) you could try something similar like in this paper:
"Energy-efficient soft real-time CPU scheduling for mobile multimedia systems".

Basically it's about custom written task scheduler for real time system which main goal is to optimize the power consumption by the CPU. I strongly believe that It is possible to write such kind of scheduler for real time Linux system, and in addition to utilize the previously mentioned C states of x86 cpu's.
