Window: Offload Modeling Report - Accelerated Regions

Use the Acceleation Regions window to view detailed information about offloaded and non-offloaded loops/functions, view source code for your loops/functions.

Review the controls available in the main report of the Offload Modeling perspective of the Intel® Advisor. In the Accelerated Regions and Summary reports, you can drag-and-drop, close/open, collapse/expand panes to change the report layout.

Review the summary offload characteristics for your application to decide if the application is recommended for offloading. The pane highlights total speedup, number of loops and functions offloaded, and a fraction of code accelerated.

Select code regions to show in the report based on offload type:

  • Show all code regions in your code.
  • Show only code regions recommended for offloading.
  • Show only code regions not recommended for offloading.

Review the detailed information about your application performance measured on a host platform and its performance modeled on a target plaform. For details about metrics reported, see GUID-76AE27D9-29E5-4C9A-A2D6-E2809F665E17.

Depending on a perspective configuration, you might see different metrics reported and some metrics might be not accurate. Refer to the following topics for interpretation details:

Examine details about estimated data transfers in a loop and memory objects tracked and review data transfer recommendations. Select a loop in the CPU+GPU table to see the data transfer estimations for it.

For details about how to read this pane, see GUID-1920F707-FEC9-4118-9E49-175C447ABA46.

Note

You need to enable data transfer analysis before running the perspective to see metrics in this pane,

Examine the source code and offload details for each source line. Select a loop in the CPU+GPU table to focus on the corresponding part of the source code.

Examine offload details about a loop. Select a loop in the CPU+GPU table to see the offload speed-up and status for this loop. If the loop is not recommended for offloading, this pane reports the reason why it is not recommended. for details, see GUID-52007588-9F95-45CB-B2B2-066BBB707979.
