Suitability Report, Site Details, Lock Row

If you choose a Target System of CPU, to view detailed characteristics of the selected site as well as its tasks and locks, click the Site Details tab. The Lock row shows the statistics for that lock.

You can reduce lock contention by using a fine-grain lock when you convert to a parallel framework. Your locks are considered to be fine-grain when you have a different lock for each data-structure or data-element that you need to synchronize. You can also eliminate locks by using other synchronization techniques, such as by using private copies of shared data.

In the upper-right part of the Suitability Report pane, if multiple parallel sites were detected during target execution, select a different Site row to display its details.

Implementing Modeling Assumptions Later When Adding Parallel Code

In the lower-right part of the Suitability Report under Runtime Modeling, changing a checkmark does not resolve an issue - it configures the modeling of your proposed parallel program execution. To implement the modeled improvements indicated by the check boxes, use specific parallel framework constructs in the Add Parallel Framework step of the workflow and consider tuning your parallel code.
