Student associations: JEMP and NECTSLab

Blog

University means many things: lessons, exams, people. Study, learn, grow. A reality of which there is often little awareness in the context of academic life is that represented by student associations. By Greta Valsecchi and Alice ArcardiniJEMP members and student, Politecnico di Milano The horizon of student associations is very broad, varied and welcoming: we deal with representation, social, political, cultural, sports and entertainment projects. In different ways and forms, the aim is to bring students closer to the academic institution, to provide tools to enrich the course of study. Projects, people and ideas are just some of the benefits available to students who want to get involved to do something more.Sometimes these realities even manage to create a very tangible bridge between the academic classroom and the world of…

High Performance Computing – Graph and data analytics

Blog

Universities have to face increasing challenges posed by new technologies, techniques, and tools. If we consider technical studies such as computer science and computer engineering, one of the key roles of the university is to help the students to learn the hard and soft skills that will enable them to continuously learn throughout their life. This is fundamental as technology keeps changing and the students should be able to apply the concepts they learn and measure themselves independently from the actual technology. By Rolando Brondolin and Alberto ParraviciniPhD Students at NECSTLab, Politecnico di Milano @NECSTLab, Politecnico di Milano Along with classical frontal lessons, Politecnico di Milano decided to add new classes to the “Passion In Action” program, to support the development of transversal, soft and social skills to encourage and…

Tracking latency in microservice environments with DEEP-mon

Blog

In our previous article we introduced HyPPO, our project aimed at optimizing workloads in Docker and Kubernetes based environments, in order to minimize power consumption. To do so, HyPPO is equipped with a monitoring agent, DEEP-mon, which exploits Linux eBPF to collect various metrics at runtime, from Docker containers and assigns a power consumption level to each container. By Tommaso Sardelli Student at Politecnico di Milano With this follow up, we would like to talk about the recent changes we made to DEEP-mon, in order to add a new metric to our arsenal: latency.As we anticipated in the first article about DEEP-mon, our target is a specific kind of applications which are referred as On-Line Data Intensive applications (OLDI). Web search, advertising, and machine translation are some examples of this…

NECSTLab 2018-2019, NECSTCamp, Innovative Teaching and NGCX: a new exciting year

Blog

The new academic year has started and at NECSTLab we are already working hard on both new and old projects. First of all, the NECSTCamp - our holistic approach towards students personal development as both persons and future engineers - is renovated. During the last months, we devoted a special attention to understand how the project could become scalable,while not losing the focus on students’ individual needs. By Sara Notargiacomo and Marco D. Santambrogio, respectively Technology Trasfer Manager and RADRL @NECSTLab, Politecnico di Milano Goal Definition Starting from this year, we are devoting a special attention to help students defining research, teaching and soft skills development goals. For this reason each students is mentored individually at least four times per academic year. This is a crucial part of their…

Who Said Academic Research Can’t Go to Market? Studying and Improving Technology Transfer Processes

Blog

Scientific research and industry are often perceived as a dichotomy, two inconciliable world dumb to never understand each other. However, when scientific research is not successfully transferred to the market, it does not fully leverage its innovation potential and does not impact on people’s lives. By Sara Notargiacomo Technology Transfer Manager @NECSTLab, Politecnico di Milano The main reason of such a gap can be found in their different time frame and incentive system. Indeed, the long period perspective of academic research is unsuitable to match with companies short-term necessities and go-to-market strategies. Furthermore, researchers do not always foresee the true potential of their research projects because they lack of business and commercialization skills. Moreover, they are often asked to postpone the publication of their work in order to comply with…

CONDOR: Convolutional Neural Networks Dataflow Optimization Using Reconfigurable Hardware

Blog

Condor is an end-to-end framework to implement Convolutional Neural Networks on FPGA, that does not require the user to have experience in FPGA programming. The framework is able to interpret models from the well-known deep learning engine Caffe. By Giuseppe Natale PhD student @Politecnico di Milano The recent years have seen a rapid diffusion of deep learning algorithms as Convolutional Neural Networks (CNNs) and, as a consequence, an intensification of industrial and academic research focused on optimizing their implementation. Different computing architectures have been explored and, among all of them, Field Programmable Gate Arrays (FPGAs) seem to be a very attractive choice, since they can deliver sustained performances with high power efficiency, as CNNs can be directly mapped onto hardware and still offer flexibility thanks to their programmability. Nevertheless, the…

I’m not malicious, detection of evasive Android malware

Blog

The increasing popularity of the smartphones attracted lots “bad actors” that wants to spread malicious software into the ecosystem for profit. To avoid being detected and maximize profit, malware uses evasive techniques. We propose an approach to combat evasive malware. By Chengyu Zheng PhD student @Politecnico di Milano How to avoid being detected With over 500 million devices and an estimated 84% market share, Android-based devices are the main target for cyber-criminals. In addition to the alarming amount of malware families and samples, evasive techniques used by malwares are becoming more and more sophisticated. With the high amount of new applications being released every month, “app store” maintainer are struggling to find a reliable solutions to analyze apps in order to recognize and isolate malicious ones. Techniques used to analyze…

FROST: a common backend to accelerate Domain Specific Languages on FPGA

Blog

Domain Specific Languages are gaining more and more interest thanks to the significant level of performance they can reach on different architectures. FROST is a common backend able to accelerate on FPGA applications developed in different DSLs. By Emanuele Del Sozzo Ph.D. student @ Politecnico di Milano Due to the reaching of the end of Dennard scaling and Moore’s law, we are experiencing a growing interest towards Heterogeneous System Architectures (HSAs) as a promising solution to boost performance and, at the same time, reduce power consumption. The combination of different hardware accelerators, like GPUs, FPGAs, and ASICs, along with CPUs, allows to choose the most suitable architecture for a specific task, and, for this reason, many high-performance systems are currently taking advantage of heterogeneity.

Breaking… the laws of robotics: attacking industrial robots

Blog

Industrial robots are everywhere: what happens if they get compromised? Is this hard? Are they attractive for attackers? How can we improve their security? To answer these questions, last year we studied the security landscape of an industrial robot and we analysed (and compromised) a widespread robot. By Marcello Pogliani PhD student at the NECSTLab, working on Systems Security Industrial robots are drastically evolving: on one side, “caged” giant robots are being complemented by smaller, “collaborative” models designed to share the workspace with human workers; on the other side, they are more “intelligent”, for example, by means of an improved interconnection for tasks such as remote maintenance, and integration with information systems. This means that robots, once “air-gapped”, are now exposed to hostile avenues. What happens (Skynet aside) if…
