Enforce Offloading for Specific Loops

Model performance on a target device for specific loops only even if they are not profitable.
If you want to check offload profitability only for specific loops or if your loop of interest is reported as not recommended for offloading to an accelerator, you can model performance only for these loops.
Info
: In the commands below, make sure to replace the
myApplication
with your application executable path and name
before
executing a command. If your application requires additional command line options, add them
after
the executable name.
To do this:
  1. Collect performance data using the
    collect.py
    script or the
    advisor
    command line interface. For example:
    advisor --collect=survey --static-instruction-mix --project-dir=./advi_results -- ./myApplication
    advisor --collect=tripcounts --flop --enable-cache-simulation --target-device=gen11_icl --project-dir=./advi_results -- ./myApplication
  2. Rerun performance modeling. For example, use the
    advisor
    command line interface:
    advisor --collect=projection --select=foo.cpp:34,bar.cpp:192 --enforce-offload --project-dir=./advi_results
Open the
Offload Modeling
results in the
Intel® Advisor
GUI or view an HTML report. The results will show performance modeled for the selected loops only.
