This document is an introduction by Paul Klint who is the head of the Software Engineering department at Centrum Wiskunde & Informatica (CWI), the national research institute for Mathematics and Computer Science in the Netherlands. CWI has been a leader in computing since 1946, hosting the first European Unix installation and connecting Europe to the Internet. It has also incubated over 20 spinoff companies in areas like computing and Internet services. The Software Engineering department focuses on research related to software analysis and transformation, foundations of software engineering, multi-agent systems, and distributed systems across four research groups. Some areas of research include using software tools and techniques to make energy systems more efficient through applications like smart energy grids, energy-aware compilers,

Compilers
● Battery life is the achilles heel of the mobile
industry
● Use software analysis and modeling
techniques to predict resource usage
● Ex. generate code that turns memory/disk off
between computation intensive code segments
● Also relevant for data centers
● Can also be applied to estimating energy usage
