Default
Off (no-track-memory-objects)
Actions Modified

=tripcounts --enable-data-transfer-analysis
collect
=projection
Usage
Use as
one
 of the following:
  • Use the
    medium
     or
    full
     data transfer with
    collect=tripcounts
     and specify
    track-memory-objects
     only for
    collect=projection
    . For example:
    advisor --collect=tripcounts --flop
    --data-transfer=full
     --project-dir=<project-dir> -- <target-application>
    advisor --collect=projection
    --track-memory-objects
     --project-dir=<project-dir>
  • Enable the
    basic data transfer analysis
     with
    collect=tripcounts
     and specify
    track-memory-objects
     for both
    collect=tripcounts
     and
    collect=projection
    :
    advisor --collect=tripcounts --flop
    --enable-data-transfer-analysis
    --track-memory-objects
     --project-dir=<project-dir> -- <target-application>
    advisor --collect=projection
    --track-memory-objects
     --project-dir=<project-dir>
Enabling can increase overhead.
Example
  1. Run Survey Analysis.
  2. Run Trip Counts and FLOP analyses and track memory objects.
  3. Model your application performance on a target device and track memory objects. 
$ advisor --collect=survey -stackwalk-mode=online --static-instruction-mix --project-dir=./advi -- myApplication

$ advisor --collect=tripcounts --flop --data-transfer=medium --target-device=gen11_icl --project-dir=./advi -- myApplication
$ advisor --collect=projection --track-memory-objects --project-dir=./advi
