10:30 Keynote #1: Fighting Internet-based Sexual Exploitation Crimes Against Children
Brian Levine, University of Massachusetts Amherst   [Abstract]


Working with law enforcement and criminologists, my research group has been developing strategies to fight online child sexual exploitation. Investigators in the US and other countries have been using our Internet-based tools daily, acquiring evidence that has resulted in many thousands of arrests for child pornography possession since 2009. Over 100 children have been rescued from abuse as a result of these cases in the last 12 months.

Using data and results from our project, I will provide an analysis of our view of the massive Internet-based child pornography trade. And I will illustrate our approach to problems in network-based criminal investigation. Our work demonstrates that even if "fully secured", the Internet would still play a role aiding and abetting crimes that harm persons. The project stands in contrast to security research focused on solving technical flaws that expose data or allow access, and to research where the victim can be protected with technical solutions. Addressing problems beyond technical flaws requires an interdisciplinary approach, as we have taken.

09:00 Keynote #2: Spanner: Google's Globally-Distributed Database
Brian F. Cooper, Google   [Abstract]


Spanner is Google's scalable, multi-version, globally-distributed, and synchronously-replicated database. It provides strong transactional semantics, consistent replication, and high performance reads and writes for a variety of Google's applications. I'll discuss the design and implementation of Spanner, as well as some of the lessons we have learned along the way. I'll also discuss some open challenges that we still see in building scalable distributed storage systems.

12:10 Keynote #3: Big Data -- Little Software?
Thomas Gross, ETH Zurich   [Abstract]


The steps of accessing, storing, and transmitting "Big Data" raise many interesting problems. But big data sets also amplify any system or software inefficiencies when large data sets require processing. So the efficiency of the generate code (and the runtime system) is crucial if we want to see widespread use of applications based on big data.

Adaptive software exploits platform and data properties to custom-tailor program executions to the current environment. However, modern platforms have many features that make it difficult to support adaptive software. Multi-core systems with a non-uniform memory architecture expose various asymmetries and complicate the runtime system's task of data management, yet even modest multi-processors exhibit NUMA properties. Processor features like prefetchers are difficult to model by a compiler and may influence the execution in unexpected ways. Finally, performance monitoring units are supposed to allow a (just-in-time) compiler to obtain the information needed to adapt the generated code. But current performance monitoring units are incomplete and, worse, subject to change over time. An adaptive software system needs performance data that is readily available, reliable, and stable.

In this talk I will discuss our experiences in modeling modern systems and argue for portable performance monitoring units that allow higher levels of the software tool chain to rely on live performance data.
