Seminar with Prof. Sara Madeira : December the 15h : CANCELED
15 dezembro 2017, 14:42 • Bruno Emanuel Da Graça Martins
The final lecture of the 2017/2018 edition of the Research Topics course was scheduled for today. However, Professor Sara Madeira will not be able to give the seminar that was scheduled for today in the Research Topics course, due to minor health problems. Today's class is therefore canceled.
There will not be a "short quiz" associated to the seminar, and the evaluation component corresponding to the "short quiz" questions will be based on the answers provided to the four previous seminars.
Until the end of the semester, students wanting to discuss aspects associated to the execution of the course project should contact me directly trough my email address, in order for us to schedule a meeting. Best wishes for the Christmas holidays.
Seminar by Stevens Le Blond (EPFL)
2 dezembro 2017, 00:21 • Bruno Emanuel Da Graça Martins
IST will host on December the 7th seminar by Stevens Le Blond, a world-renowned researcher from EPFL.
The attendance to this seminar will be considered for the course evaluation in the same way as in the case of seminars from the “INESC-ID Distinguished Lectures” series.
Towards providing digital immunity to humanitarian organisations
Stevens Le Blond (EPFL)
Date: December 7, 12:30pm
Location: DEI Meeting room 0.19 (informática II building)
Abstract:
Abstract:
Humanitarian action, the process of aiding individuals in situations ofcrises, poses unique information-security challenges due to natural ormanmade disasters, the adverse environments in which it takes place, andthe scale and multi-disciplinary nature of the problems. Despite thesechallenges, humanitarian organizations are transitioning towards astrong reliance on digitalization of collected data and digital tools,which improves their effectiveness but also exposes them to computersecurity threats. This talk presents the first academic effort seekingto understand and address the computer-security challenges associatedwith the digitalizing humanitarian action.
First, I will describe a qualitative analysis of the computer-securitychallenges of the International Committee of the Red Cross (ICRC), alarge humanitarian organization with over sixteen thousand employees,legal privileges and immunities, and over 150 years of experience witharmed conflicts and other situations of violence worldwide. Second, Iwill present a research agenda to design and implement anonymitynetworks, block chains, and secure-processing systems addressing thesechallenges, and to deploy them in collaboration with the ICRC. I willclose with a discussion on how to generalize our approach to providedigital immunity to humanitarian and other at-risk organisations.

After having enjoyed sun bathing at INRIA Sophia-Antipolis, and actualbathing at the MPI-SWS, Stevens is now skiing in Switzerland where he'sa research scientist at EPFL. His Ph.D. thesis on the privacy analysisof the Skype protocol has has led to privacy enhancements of the Skypearchitecture which is daily used by hundreds of millions of users. Hispost-graduate work on anonymity networks was qualified of the“[next-generation] anonymity network closest to deployment” byArsTechnica. He is one of the first academic researchers to have studiedthe computer security practices of politically-motivated attackers andtheir targets. His research has been published in leading conferencessuch as Oakland, Usenix Security, NDSS, SIGCOMM, and IMC.

Rethinking Memory System Design (and the Computing Platforms We Design Around It)
Rethinking Memory System Design (and the Computing Platforms We Design Around It)
IST anfiteatro FA3| December 4th | 11h
Abstract
The memory system is a fundamental performance and energy bottleneck in almost all computing systems. Recent system design, application, and technology trends that require more capacity, bandwidth, efficiency, and predictability out of the memory system make it an even more important system bottleneck. At the same time, DRAM and flash technologies are experiencing difficult technology scaling challenges that make the maintenance and enhancement of their capacity, energy efficiency, and reliability significantly more costly with conventional techniques. In fact, recent reliability issues with DRAM, such as the RowHammer problem, are already threatening system security and predictability.In this talk, we first discuss major challenges facing modern memory systems in the presence of greatly increasing demand for data and its fast analysis. We then examine some promising research and design directions to overcome these challenges. We discuss three key solution directions: 1) enabling new memory architectures, functions, interfaces, via more memory-centric system design, 2) enabling emerging non-volatile memory (NVM) technologies via hybrid and persistent memory systems, 3) enabling predictable memory systems via QoS-aware memory system design. If time permits, we will also discuss research challenges and opportunities in NAND flash memories.

Onur Mutlu is a Professor of Computer Science at ETH Zurich. He is also a faculty member at Carnegie Mellon University, where he previously held the William D. and Nancy W. Strecker Early Career Professorship. His current broader research interests are in computer architecture, systems, and bioinformatics. He is especially interested in interactions across domains and between applications, system software, compilers, and microarchitecture, with a major current focus on memory and storage systems. A variety of techniques he and his group have invented over the years have influenced industry and have been employed in commercial microprocessors and memory/storage systems. He obtained his PhD and MS in ECE from the University of Texas at Austin and BS degrees in Computer Engineering and Psychology from the University of Michigan, Ann Arbor. His industrial experience spans starting the Computer Architecture Group at Microsoft Research (2006-2009), and various product and research positions at Intel Corporation, Advanced Micro Devices, VMware, and Google. He received the inaugural IEEE Computer Society Young Computer Architect Award, the inaugural Intel Early Career Faculty Award, faculty partnership awards from various companies, and a healthy number of best paper or "Top Pick" paper recognitions at various computer systems and architecture venues. His computer architecture course lectures and materials are freely available on YouTube, and his research group makes software artifacts freely available online.
