Parallel Programming with OmniThreadLibrary

This book is 100% complete

Completed on 2019-03-01

About the Book

Parallel programming is hard. Your best bet to a stable application is a good multithreading framework and for Delphi that means OmniThreadLibrary (www.omnithreadlibrary.com).

This book - which is, incidentally, written by the very author of the OmniThreadLibrary - walks you through different parts of the library. It gives an overview of low-level multithreading approach (programming with tasks), high-level approach (programming with abstractions) and describes various helper functions and data structures implemented in the library.

The book also walks you through multiple examples which demonstrate different aspects of multithreaded programming - from parallel execution of http requests to creation of database connection pools and multithreaded user interfaces.

A printed version is available on Lulu. If you'd like to buy both electronic and paper edition, buy the printed version first as that will give you a coupon for the e-book.
