- Mechanisms for implementing multithreading and multiprocessing available in C++.
- Standard library implementation - elements from C++14 to present (C++2a)
- Implementation available in Boost - differences from the standard library
Processes and threads

- Process and thread synchronization mechanisms
- Structural implementation of synchronization
- Specificity of the implementation of multithreading in the object-oriented approach (role of the RAII pattern)
Memory model in language C++
- Objects and places in memory
- Scheduling operations and enforcing them
- Relations: synchronization, priming, ordering of operations for atomic actions, release sequences

Enjoyed the flexibility and variety of topics, the combination of trainings and exercises meant that I could apply what I'd learnt straight away. I also enjoyed the projects on the last day to bring everything together.

Interactivity, time for self-contained programming. I learn easier if I have the chance to find out the answer and not just telling me it. It was also a very good thing that the training was well-planned, we kept coffee pauses and the training did not lose my attention. The trainer had very deep knowledge in C++, we felt we could ask anything.
Barna Szecsi - GIS Europe SE
Course - C++ for Embedded Systems
The instructor's knowledge.

The details on how compiler behaves depending on to the syntax usage. The "Quiz" sections are very stimulating
