Apply threading to functional-decomposition problems in the Implementation Phase of application development. Functional-decomposition problems are situations where the roles of different threads are defined by having different functionality (as opposed to identical functionality that is applied to different data).
Prevent negative performance impacts in application execution due to spin-wait loops on systems that support Hyper-Threading Technology.
A spin-wait loop is a technique used in multithreaded applications whereby one thread waits for other threads. The wait can be required for protection of a critical section, for barriers, or for other necessary synchronizations. Typically, the structure of a spin-wait loop consists of a loop that compares a synchronization variable with a predefined value as shown in the following sample code:
