Window:
Offload Modeling
Report - Accelerated Regions

Use the
Accelerated 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 platform. For details about metrics reported, see Accelerator Metrics.
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:
Switch between the
Data Transfer Estimations
tab and
Details
tab.
In the
Data Transfer Estimations
tab, 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. Click a recommendation to expand it and view hints for offloading your code to another accelerator, code samples, and links to useful resources.
For details about how to read this pane, see Examine Data Transfers for Modeled Regions.
You need to enable data transfer analysis before running the perspective to see metrics in this pane,
In the
Details
tab, view performance metrics for a selected function/loop.
Advanced view pane enables you to:
  • Examine the source code for selected functions/loops in the
    Source
    tab. Select a loop in the
    CPU+GPU
    table to focus on the corresponding part of the source code.
    Right-click a code line and click
    View Source
    to open the source view. Double click a code line in the source view to open it in code editor.
  • View the execution details for a selected function/loop in the call stack using the
    Top-Down
    tab.
  • Examine recommendations that provide guidance and code samples to resolve the issues found by
    Intel Advisor
    using the
    Recommendations
    tab. Use the drop-down to expand code snippets if you need them.
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 Investigate Non-Offloaded Code Regions.
This pane is collapsed by default. Click an arrow icon on the top of it to expand the pane.
