Vectorization Accuracy Presets

For each perspective, Intel® Advisor has several levels of collection accuracy. Each accuracy level is a set of analyses and properties that control what data is collected and the level of collection details. The higher accuracy value you choose, the higher runtime overhead is added.

The following accuracy levels are available:

Comparison / Accuracy Level






5 - 8x

10 - 40x
