Multi-Paradigm Programming with Modern C++ - Thread Pools

The video tutorial explains the concept of thread pools, their benefits, and how to implement a basic thread pool using condition variables, mutexes, and queues. It covers popular libraries like Microsoft's PPL, Intel TBB, and Boost for thread management. The tutorial details the implementation of a thread pool, including the destructor, schedule function, and handling special cases in the thread function.

What is one of the main advantages of using a thread pool?

• It allows for the creation of unlimited threads.

• It provides a common interface for running background tasks.

• It automatically optimizes memory usage.

• It eliminates the need for a queue.

Which library is recommended for thread pools on Windows?

• Microsoft's Parallel Patterns Library

• Intel Thread Building Blocks

• Standard Template Library

• Boost Thread

What pattern does the thread pool implementation follow?

• Producer-Consumer Pattern

• Factory Pattern

• Singleton Pattern

• Observer Pattern

What is the role of the 'executable' interface in the executor class?

• To provide logging capabilities

• To define a pure virtual function for tasks

• To manage memory allocation

• To handle thread synchronization

What is the purpose of the 'schedule' function in the executor class?

• To initialize the thread pool

• To schedule tasks on worker threads

• To log task execution

• To terminate all threads

Why is a mutex used in the thread pool implementation?

• To increase the speed of task execution

• To ensure only one thread accesses the queue at a time

• To automatically distribute tasks

• To reduce memory usage

What happens when the queue is empty in the thread pool?

• Tasks are executed in a random order

• All threads terminate immediately

• Threads wait for the condition variable to be signaled

• New threads are created

What is the function of the atomic boolean 'active' in the executor class?

• To track the number of active tasks

• To indicate when threads should shut down

• To manage memory allocation

• To log task execution

What is the significance of using a condition variable in the thread pool?

• It allows threads to execute tasks in parallel

• It keeps threads suspended when the queue is empty

• It automatically optimizes task execution

• It eliminates the need for a mutex

What should be done if a task is scheduled on an executor being destroyed?

• The task should be executed immediately

• The task should be ignored

• The executor should be restarted

• An exception should be thrown
