If your tasks access the same memory locations, then, left to themselves, they will tend to trip over each other. You can solve this by adding synchronization code to make sure the tasks are well-behaved when they access shared memory locations, but synchronization code can be tedious to add and hard to get right, and it is easy to end up with tasks that spend more time doing synchronization than doing work.
Intel® Advisor Memory Access Patterns tool performs extensive analysis of your running program to predict memory access problems. After you change the sources, run the Memory Access Patterns tool again to check the memory access strides.
While the Memory Access Patterns tool is running your application program:
After you choose the parallel framework, you need to add the parallel framework to your build environment.
Adding the parallel framework to your build environment can require installing additional software, as well as modifying build scripts, modifying project properties , and so on, as described in the following sections.
