Need of Thread Pool in C++
In C++, a thread pool is needed in the following cases:
- When several activities must be completed simultaneously, like in server applications, parallel processing, and parallelizing loops, thread pools are frequently utilized.
- Thread Pools enhance overall performance by lowering the overhead of thread generation and destruction through thread reuse.
Thread Pool in C++
The Thread Pool in C++ is used to manage and efficiently resort to a group (or pool) of threads. Instead of creating threads again and again for each task and then later destroying them, what a thread pool does is it maintains a set of pre-created threads now these threads can be reused again to do many tasks concurrently. By using this approach we can minimize the overhead that costs us due to the creation and destruction of threads. This makes our application more efficient.
There is no in-built library in C++ that provides the thread pool, so we need to create the thread pool manually according to our needs.
