Guided Auto Parallelism (GAP) is a feature of the Intel compiler that offers selective advice and, when correctly applied, results in auto-vectorization or auto-parallelization for serially-coded applications. Using the [Q]guide option with your normal compiler options at O2 or higher is sufficient to enable the GAP technology to generate the advice for auto-vectorization. Using [Q]guide in conjunction with [Q]parallel will enable the compiler to generate advice for auto-parallelization.
In this tutorial, you will:
Prepare the sample application.
Run guided auto parallelism.
Analyze the guided auto parallelism report.
Implement the report recommendations.
