Syntax

--data-transfer-histogram
--no-data-transfer-histogram
Default
Off (no-data-transfer-histogram)
Actions Modified
collect
=projection
Usage
Use as
one
 of the following:
  • Use the
    medium
     or
    full
     data transfer with
    collect=tripcounts
     and specify only
    data-transfer-histogram
     for
    collect=projection
    . For example:
    advisor --collect=tripcounts --flop
    --data-transfer=medium
     --project-dir=<project-dir> -- <target-application>
    advisor --collect=projection
    --data-transfer-histogram
     --project-dir=<project-dir>
  • Enable the
    basic data transfer analysis
     and
    track-memory-objects
     with
    collect=tripcounts
     and specify
    track-memory-objects
     and
    data-transfer-histogram
     for
    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
    --data-transfer-histogram
     --project-dir=<project-dir>
Example
With the medium data transfer analysis:
  1. Run Survey Analysis.
  2. Run Trip Counts and FLOP analyses of the Characterization stage.
  3. Model your application performance on a target device and enable data transfer histogram. 
advisor --collect=survey --static-instruction-mix --project-dir=./advi_results -- ./myApplication

advisor --collect=tripcounts --flop --data-transfer=medium --project-dir=./advi_results -- ./myApplication
advisor --collect=projection --data-transfer-histogram --project-dir=./advi_results
