After you locate the parts of your program that use significant CPU time, add Intel® Advisor annotations into your sources to mark (propose) the likely places where you might add parallelism. You run Intel Advisor tools to collect data about your running program.
To begin, use the Survey or other profiling tool to identify parts of the loops or functions that use significant CPU time. Focus on these code regions, especially those whose work can be performed independently and distributed amongst multiple cores. By adding annotations, you mark proposed parallel code regions for the Intel Advisor Suitability and Correctness tools to examine in detail to predict your program's parallel behavior.
