Intel® Threading Building Blocks (Intel® TBB)Synchronization Code
After you add
Intel® Threading Building Blocks (Intel® TBB)synchronization code (such as mutexes), but before adding the constructs that cause the program to use parallel execution, you should test your serial program. The synchronization code may introduce problems if you have inadvertently used a non-recursive mutex in a recursive context, or if your edits accidentally changed some other piece of program behavior.
It is much easier to find these problems in the serial version of your program than it will be in the parallel version.
