Prerequisites
Knowledge of .Net or an object-oriented programming language.
Course schedule
1 Basic multithreading tools
- What is a thread? Notion of thread and process.
- Memory sharing by threads.
- ThreadPool to avoid thread creation.
- AppDomain for module isolation.
- Multi-process synchronization: Event, Mutex and Semaphore synchronization objects.
- Intraprocess synchronization: the framework's Monitor class and the lock keyword.
- The danger of a fatal embrace and how to detect it.
- ReaderWriterSlimLock class. Interlocked class.
Hands-on work
Synchronization of two threads, data producer and data consumer. Use of standard classes.
2 Basics of the Task Parallel Library
- Start tasks and get results.
- await and async keywords.
- Continuations to manage normal end, on exception, cancellation.
- Event Asynchronous Pattern versus Task Asynchronous Pattern.
- Parallel Linq to run Linq queries in parallel.
- Handling exceptions and cancellations with Parallel Linq.
- Parallel.ForEach to launch data-driven tasks.
- Parallel.For for aggregate calculations.
Hands-on work
Calcul d’une somme en parallèle avec différents outils. Démarrage de Tasks et utilisation de await et async.
3 Find out more about Task Parallel Library
- Select where to run a task: TaskScheduler.
- ConfigureAwait to optimize recovery.
- Report progress with Progress<T>.
- Task cancellation with CancellationTokenSource.
- IAsynEnumerable<T> and await foreach from C# 8.
Hands-on work
Job cancellation and progress report in the crawler.
4 Collections for the competition
- Immutable collections when a snapshot of the data is sufficient.
- Concurrent collections for protected sharing of modified data.
- Collections for producer/consumer issues.
Hands-on work
Optimizing and protecting the crawler with competing collections.
5 Task Parallel Library Dataflow
- Task Parallel Library Dataflow for execution in parallel networks.
- The different Dataflow blocks, and how they are linked.
- Conditional block linking.
- Dataflow and data buffering.
- Dataflow and parallelized processing.
- Dynamic block linking.
Hands-on work
Decoupled communication between a web server and a backend.
6 Reactive Extension for reactive programming
- Reactive Extension to treat events as sequences.
- Reactive design model.
- Hot and cold observables, event data subscription.
- Linq-style data processing.
Hands-on work
Provide a reactive autosuggestion implementation.
