What is the default value for thread pool size?
The Min Thread Pool Size property specifies the minimum number of threads the server initiates upon startup. The default value is 2. Min Thread Pool Size represents a hard limit for the maximum number of active threads that can run simultaneously, which can become a bottleneck for performance.
How do you find optimal number of threads?
I came up with a method to calculate the optimal number of threads by making two measurements of processing times Tn and Tm for two arbitrary number of threads ‘n’ and ‘m’. For linear algorithms, the optimal number of threads will be N = sqrt ( (mn(Tm*(n-1) – Tn*(m-1)))/(nTn-mTm) ) .
Is there a thread pool in C + + 11?
Here’s the github: https://github.com/Tyler-Hardin/thread_pool. This is another thread pool implementation that is very simple, easy to understand and use, uses only C++11 standard library, and can be looked at or modified for your uses, should be a nice starter if you want to get into using thread pools:
Which is the best definition of a ThreadPool?
A threadpool is at core a set of threads all bound to a function working as an event loop. These threads will endlessly wait for a task to be executed, or their own termination.
Is there a ThreadPool with no dependencies outside of STL?
A threadpool with no dependencies outside of STL is entirely possible. I recently wrote a small header-only threadpool library to address the exact same problem. It supports dynamic pool resizing (changing the number of workers at runtime), waiting, stopping, pausing, resuming and so on.
Why do you need inter-thread communication in C + +?
To give the threads something meaningful to do, you have to design a system of inter-thread communication, both for the purpose of telling the thread that there’s something to do, as well as for communicating the actual work data.
