08:45 → 09:45 Software Design L1: Parallelism in a Modern HEP Data Processing Framework

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.

12:30 → 13:30 Software Design L3: Understanding, Debugging and Profiling a Complex Multithreaded Application

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.

Do not miss the Estonian National Museum! https://erm.ee/en
The Estonian National Museum was founded in Tartu in 1909 on the initiative and with the support of the nation – with the task to protect and develop the history and culture of Estonia. As in many other European countries, primary importance was attached to preserving the old, fading peasant culture. Also considered essential was gathering and looking after artefacts contributing to better understanding of cultural development, archaeological findings, old coins, books, manuscripts and historical records.

Over time, a number of other museums, archives and libraries were founded, and the Estonian National Museum re-focused mainly on folk culture. Until World War II, the Estonian National Museum accumulated everything related to the Estonian national heritage. The fact that the museum had become a recognised memory institution by the 1930s was greatly supported also by contacts with foreign countries (Finland, Sweden, Germany, France etc), both in exchanging scientific literature, participating in study and research trips and scientific conferences and also through organising exhibitions outside Estonia.

Today, Estonian National Museum preserves the feeling of continuity and tradition. The museum is the generator and developer of cultural dialogue which links the past and the future. ENMs role as a centre of ethnological research is to record, study and interpret culture as a way of life, taking into account its periodical, spatial and social diversity. The Museum's function as a contemporary cultural and tourist centre is to show our cultures uniqueness and primeval power of creation to every Estonian and visitor.

The main emphasis of research and collecting is on Estonian everyday life in the second half of the 20th century as well as on the Estonian diaspora and audiovisual, archival and artifactual data from Finno-Ugric cultures. Through the Museum’s exhibitions and events, one can take a look at Estonians’ everyday lives in different periods. Interactive displays offer hands-on experience; it is possible to observe what an Estonian home looks like, explore Estonian cuisine and make oneself familiar with local dress, language and customs. Attention is also paid to the cultures of other nations, especially those of the Finno-Ugric peoples.

12:30 → 13:30 Exercises 2: Data Analysis

There will be 3 sets of exercises covering basic properties of PDFs and Monte Carlo generators, Maximum Likelihood fit, and Hypothesis testing. Students will be given realistic but simplified problems where key concepts from statistics need to be applied in order to provide scientific interpretation of data. Each set of exercises consists of 5 problems that will help guide the student. Data is provided in a simple text file and can be analysed with any programming language that offers libraries for statistical analysis (Python or C++ are recommended).

16:30 → 17:30 Exercise 3: Software Security

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.

11:30 → 13:00 Visits to GSCAN/Tartu Observatory

Field trip to GScan
GScan is a company near Tartu that is redefining the boundaries of 3D scanning with Muon Flux Technology (MFT) detectors.
GScan is using naturally occurring cosmic-ray induced muons, electrons and positrons as the source for performing 3D scanning and chemical composition analysis. Utilising a natural source makes every GScan system radiation safe - no harm to the surrounding people nor the environment itself. Their solutions are modular and highly-scalable, using the in-house developed 1m x 2m detector array modules. With a strong base of startup mindset, fundamental and information sciences, a highly modern manufacturing industry, coupled with high work ethics coming from Estonia has provided us with a strong competitive edge for developing such a complex technology.

Field trip to Tartu Observatory
Tartu Observatory is an Estonian space centre whose main task is research and development. They train young scientists in astronomy, remote sensing, and space technology, and are a recognised partner in international networks. Tartu Observatory has accredited test laboratories where companies can test their equipment in different environmental conditions. The laboratory complex of the observatory offers environmental testing of devices and optical measurements. The laboratories include special electrostatic discharge (ESD) safe areas, a cleanroom and an anechoic environment.
Tartu Observatory´s history goes back to the 19th century when the Tartu Old Observatory (Tartu Tähetorn) was built. There, astronomer F. G. W. Struve created the meridian arc to determine the shape and size of the globe, this geodetic arc is listed under UNESCO World Heritage. In the mid 20th century scientists led by Einasto discovered the honeycomb-like structure of the universe.
We`ll visit the laboratories, have mini lecture about data gathering and science in soviet times and of course visit the big telescope (1.5 m mirror telescope AZT-12 with a long-slit spectograph in the Cassegrain focus, providing spectral resolution of R~ 100 to 12000).
