Multi-threading is a key approach to scale programs. However, dealing with multiple threads is also a source of trouble. Running code in parallel is great as long as this code doesn't need concurrent access to the same objects and synchronization. With concurrency, care must be taken to ensure that multiple threads is not counter-productive. As usual, usings C++ as a language brings additional challenges.

In this workshop we will experience the basics of multi-threading and concurrency on a full program of significant size. By start with a pretty simple single-threaded program, which reads and writes sequentially, and perform live-programming to convert it into a well-working multi-thereaded program reading and writing in parallel.

During this change you will see the issues and pain that can occur when using multiple threads and learn how to deal with them. In fact, you will learn how to start threads in C++, how to deal with exceptions, how to synchronize code (using mutexes and atomics), and how to deal with synchronization (using condition variables). This all is discussed while falling intro traps and solve issues step by step.

The workshop is a helpful experience to understand multi-threading and concurrency way better and learn how to benefit from the various C++ features for multi-threaded programming.

The training can be tailored according to your current context, knowledge, and interests.
