Modern C++ Software Design (Advanced)

This advanced C++ training is a course on object-oriented (OO) software design with the C++ programming language. The focus of the training are the essential OO and C++ software development principles, concepts, idioms, and best practices, which enable programmers to create professional, high-quality code. Additionally, the course gives insight into kernel development with C++. The course will not address special areas and applications of C++, such as for instance Template Meta Programming (TMP), or the quirks and curiosities of the C++ language. It rather teaches guidelines to develop mature, robust, maintainable, and efficient C++ code.

Since 2020 we provide two types of C++ courses, each offered two times per year:

  • intermediate: March 8-11, 2022, and June 21-24, 2022 
  • advanced: May 3-6, 2022, and Nov. 22-25, 2022 (this course)

with two different levels of prerequisites.

Prerequisites and content levels

Prerequisites and Language Hints Advanced C++

At least two to three years of experience with the language is needed. This includes a solid knowledge of the syntax of C++, experience with the standard library (std::vector, std::list, …), hands-on experience with both template-based and inheritance-based designs and some experience with design patterns.

In the on-site course, participants will be provided Linux machines. For that reason some familiarity with Linux is beneficial. Alternatively, participants will be able to use their own machines. Any operating system (Windows, Linux, MacOS, ...), any IDE/editor (MS Visual Studio, CLion, vi, emacs, ...) and any compiler capable of at least C++14 (GCC, Clang, MSVC, ...) can be used. In the online course, participants are expected to use their own devices. The programming tasks, including both Makefiles and CMake files, will be distributed before the course.

The course language is German. The slides are in English.

If you want a similar course in English, then please look at the 3- or 4-day advanced C++ courses at LRZ , the 4 day course at VSC in Vienna or directly on Klaus Iglberger's course page.

Content levels
  • Basic: 3 hours
  • Intermediate: 10 hours
  • Advanced: 14 hours

On-site course & COVID rules

Although this event is a training course, another important aspect is the scientific exchange between participants, which did not work as well as we hoped in our online courses.

The concept to enable this communication among our participants consists of

  • common coffee and lunch breaks, and
  • if you want and permitted by official COVID-19 rules, working together in groups of two during the exercises.

For your safety, we allow only completely vaccinated, or fully recovered, or participants tested negatively on COVID-19 on all days. Note that participation with tests might be prohibited when the course starts or even while the course runs. In the course room and when not eating/drinking, FFP2 masks are required. See registration page for details. Of course, these rules also apply to the instructors.

We strongly recommend to choose travel options and hotels with the possibility to cancel (even close to the event) because we might be forced to deliver the course as an online course.

Registration information

Register via the button at the top of this page.

Registration closes on April 17, 2022 (extended registration phase).

Late registrations after that date are still possible according to the course capacity, possibly with reduced quality of the handout.


Students without Diploma/Master: 35 EUR.
Students with Diploma/Master (PhD students) at German universities: 75 EUR.  
Members of German universities and public research institutes: 75 EUR.
Members of universities and public research institutes within EU or PRACE member countries: 150 EUR.   
Members of other universities and public research institutes: 300 EUR.  
Others: 780 EUR.

Our course fee includes coffee breaks (in classroom courses only).


There will be several shorter breaks and a lunch break every day. Unfortunately, due to the COVID-19 pandemic, we can only offer water (carbonized and natural) and apple juice in single bottles in breaks but no coffee. If you would like to drink coffee you might bring it in a thermos yourself or you can go to a nearby bakery. All bottles that contain liquids must be safely lockable by a screw cap to protect the laptops and underfloor in the lecture hall.

We recommend that you bring your own lunch. As of today, due to COVID-19 restrictions, there will be no possibility to have lunch at the canteen. We are only aware of the following two publicly accessible nearby places for lunch:

  • A food truck from 11:00-14:00, see "Standort Allmandring 30" at this website, approximately 300 m from HLRS,
  • Bakery Sehne, near bus stop "Im Lauchhau", approximately 400 m from HLRS.

HLRS is part of the Gauss Centre for Supercomputing (GCS), which is one of the six PRACE Advanced Training Centres (PATCs) that started in Feb. 2012.

HLRS is also member of the Baden-Württemberg initiative bwHPC.

This course is also provided within the framework of the bwHPC training program. This course is not part of the PATC curriculum and is not sponsored by the PATC program.
