Energy Efficient Computing Systems (EECS)

Energy efficiency is the key design challenge for future computing systems, ranging from wireless embedded client devices to high performance computing centres. The Energy Efficient Computing Systems (EECS) research initiative has been established in 2012 by the Faculty for Information Technology, Mathematics and Electrical Engineering, NTNU, to precisely respond to the related research challenges met in the current socio-economic context. The EECS Group's primary research efforts will focus on improving the energy efficiency of computing systems across all abstraction layers - spanning disciplines such as nano-scale electronics, computer architecture and system software and applications.


Ubiquitous Energy Efficiency

Computing systems are often perceived as clean and environmentally friendly. However, the energy used to power these systems is produced in the same fashion as the energy that powers all other systems. The figure to the left links the production of electric energy to present and future computing system usage scenarios.

This illustration represents the various computing systems in four main categories: home and professional computing, mobile computing, high performance computing and ultra-low energy computing. For each of these categories, the main limitations have been identified as follows: cooling system capacity, battery capacity, the monetary cost of energy or the total energy consumption during lifetime of the system, respectively. As a result, energy efficiency stands out as the primary design objective.


The research activity of EECS is organised around research projects. Currently, EECS is contributing to the following projects:

EECS has been selected as one of seven groups at NTNU to get special support for work with applications to EU's Horizon 2020 research program. In this context Professor Per Gunnar Kjeldsberg is project leader working together with Associate Professor Magnus Jahre who acts as process leader.


EECS aims to disseminate its research results to the scientific community through scientific publications. EECS researchers have published at the highest international level.

EECS collaborates with both leading companies and universities, at the national and international level.

How does EECS interact with industry partners? Typically the company contributes to the research or teaching activities of EECS researchers. In other cases, the partnership can translate into a joint application for external funding opportunities.

How does EECS interact with research partners? Usually a research partner co-authors a paper  with an EECS researcher or may contribute to a research funding proposal.
