14:00 - 15:00
First lecture starts with a definition of computer security and an explanation of why it is so difficult to achieve. The lecture highlights the importance of proper threat modelling and risk assessment. It then presents three complementary methods of mitigating threats: protection, detection, reaction; and tries to prove that security through obscurity is not a good choice.

15:00 - 16:00
To start, we discuss some of the characteristics of software projects for high energy physics, and some of the issues that arise when people want to contribute to them. This forms the framework for the Software Technologies Track. We then continue with a brief introduction to software engineering from the perspective of the individual contributor, both as a formal process and how it actually affects what you do. The lecture discusses several categories of tools & techniques you can use to make yourself more productive and effective. Continuous testing and documentation has proven to be important in producing high quality work, but it's often difficult to do; we discuss some available approaches. Many problems require specific tools and techniques to solve them effectively: We discuss the examples of performance tuning and memory access problems.

In this talk we will talk about the way in which in the 21st Century we will probably be limited to design and create by what we can compute, not by what we can measure, as was the case in the 20th Century. We will discuss about current trends in HPC technology, hardware and software alike, the landscape of Supercomputing in terms of computing architectures and likely development trends, as well as the opportunities that HPC offers for many scientific and engineering domains.

In the practice session, a range of typical security vulnerabilities will be presented. The goal is to learn how they can be exploited (for privilege escalation, data confidentiality compromise etc.), how to correct them, and how to avoid them in the first place! Students will be given small pieces of source code in different programming languages, and will be asked to find vulnerabilities and fix them. The online course documentation will gradually reveal more and more information to help students in this task. Additionally, students will have a chance to try several source code analysis tools, and see how such tools can help them find functionality bugs and security vulnerabilities.

HEP software is built by huge teams. How can this be done effectively, while still giving people satisfying tasks to perform? Large systems are a hard problem, and this lecture focuses on the current techniques for dealing with it. Use of central source control has become routine, so we build on that understanding to discuss distributed systems like Git. We then discuss the larger area of release & distributing via a package versioning system vs. a distributed build system (e.g. Git and CMake). Now that we've covered both individual and group work, we go back to the software engineering topics of the first lecture to see how these fit together. How does our individual work affect the ability of the entire project to proceed? What are tools and techniques that will improve both our individual work, and out contributions to the whole? We close with a summary of observations.

08:45 - 09:45
Even though the miniaturization of transistors on chips continues like predicted by Moore's law, computer hardware starts to face scaling issues, so-called performance 'walls'. Probably, the best known is the 'power wall', which limits clock frequencies. Amongst others, a way of increasing processor performance remains now to integrate many cores in the same chip. At the same time, the upcoming LHC upgrade will increase the required CPU power drastically. Both problems challenge the current way of software design in high energy physics (HEP). Developers in high energy physics are forced to re-think their ways of software design and need to move to massively parallel applications. This lecture will explain the current HEP software design, the hardware and physics issues that need to be tackled, and possible approaches to achieve the required level of parallelization.

Software Design L3: Understanding, Debugging and Profiling a Complex Multithreaded Application
Andrei Gheata
(

10:00 - 11:00
Dealing with a parallel application is complex. We need to use procedures to rise fences to protect against mistakes, like static analysis tools allowing to find bugs in an automatic way. We also need to use tools to inspect and manipulate the behavior of programs at runtime, like the GDB debugger. Finally, profilers such as igprof can help us understand the performance bottlenecks of an application and get more insight on its efficiency. The objective of this lecture is to become familiar with these tools and be able to apply them in multithreaded programs.

The objective of this series of two lectures is to present the fundamentals of networking, to help those involved in scientific computing to design systems or programmes involving at-a-distance actions, as well as to better understand their behaviours. Therefore, the aim is not to dwell on the nitty-gritty details, formats, or protocols, but to extract and synthetize the knowledge useful to the non-networkers. The first lecture will focus on the transport network and will present the fundamental principles of IP, its historical limits and recent enhancements that led it to become a universal transport technology.

Two traditional programming models are considered: MPI as a representative of the distributed memory model, and OpenMP that offers a very simple and in the same time efficient way to specify multithreading computation. We intend to present also how to create a basic hybrid program based on both, and how this approach could efficiently exploits the hardware facilities.

The first part of hands-on exercises aims to improve understanding of basic parameters in IO systems: • network and media latency • access patterns • OS caching • bottlenecks and optimization strategies for local and remote data access. Few essential Linux tools will be introduced to monitor and measure IO performance avoiding bias introduced by OS caching. Students will experience and measure the impact of latency and access patterns on IO performance. The second part covers the concept of parallelism and redundancy in storage system. We will apply the technology of Cloud storage systems to store and retrieve files in our local desktop cluster using a distributed hash table to locate files or file fragments and a REST interface to do GET, PUT or DELETE operations on these. The exercises conclude with the implementation and performance tuning of a RAID verification algorithm.

09:45 - 10:30
Disease diagnostic, biomarkers discovery, drugs development, personalized medicine, land cover mapping, biodiversity conservation, predictive maintenance, product development, process optimization, autonomous driving, smart mobility – building - factory, fraud detection, recommendation systems etc. – this is an extremely short list of applications where data science plays an essential role. Data science touches all economic sectors and is truly impacting almost every aspect of our everyday life. This vast diversity of applications can be narrowed down to much smaller set of tools and methods that provide with more or less standard solutions to the very wide range of real life challenges. This is the role of a data scientist who works hand in hand with a domain expert to tailor the optimal solution for the goal in mind. In the industrial sector, data is generated in all areas of activity and all industries, from the hiring process, to the development and production of a product (a product can be a car, an assurance policy, a medical prescription, a market survey etc.) to the customer itself. Of much importance for most industries is also the data generated during the entire life cycle of the products, extremely valuable in order to design better products. The role of a data scientist is to extract knowledge from data by means of standard algorithms and methods and to create new assets for the business. We propose to showcase the variety of use cases issued from the manufacturing industries paired with similar use cases from other application areas. For example a comparison of image processing in medical imaging vs. automated optical inspections on manufacturing lines, recommendation systems in manufacturing vs recommendation systems in E-commerce or application of statistical tests for biomarkers discovery vs. root cause analysis of failures on a production line.
