<em>ISCA '18: 45th International Symposium on Computer Architecture, Keynote</em>
</p>
<p>Employing Machine Learning to generate models from data is replacing traditional software development in many
applications. This fundamental shift in how we develop software is known as Software 2.0. However, the
continued success of Software 2.0 relies on the availability of powerful, efficient and flexible computer
systems. </p>
<p>This talk will introduce a design paradigm that exploits the characteristics of Software 2.0 to create
computer systems that are optimized for both programmability and performance. The key to the design paradigm
is a full-stack approach that integrates algorithms, domain-specific languages, advanced compilation
technology and new hardware architectures.</p>
