Concurrency and Multithreading with Modern C++

2 days
ModCPPmulti - Version:1
Description
Course will combine theory and hands-on live code demonstration. Attendees will practice learnt concepts and techniques by solving specially designed exercises. Hands-on practice is ~30% of each session time.
Intended audience
Software engineers with hands-on experience using C++11/14/17. Prior multithreading experience is not required but is recommended.
