count-memory-objects-accesses

Count the number of accesses to memory objects created by code regions.

Syntax

--count-memory-objects-accesses
--no-count-memory-objects-accesses
Default
Off (no-count-memory-objects-accesses)
Actions Modified
collect
=projection --data-reuse-analysis
Usage
Use as
one
 of the following:
  • Use the
    full
     data transfer with
    collect=tripcounts
    :
    advisor --collect=tripcounts --flop
    --data-transfer=full
     --project-dir=<project-dir> -- <target-application>
    advisor --collect=projection
    --data-reuse-analysis --count-memory-objects-accesses
     --project-dir=<project-dir>
  • Enable the
    basic data transfer analysis
     and
    data-reuse-analysis
     with
    collect=tripcounts
    :
    advisor --collect=tripcounts --flop
    --enable-data-transfer-analysis
    --data-reuse-analysis
     --project-dir=<project-dir> -- <target-application>
    advisor --collect=projection
    --data-reuse-analysis --count-memory-objects-accesses
     --project-dir=<project-dir>
Example
With the full data transfer analysis:
  1. Run the Survey analysis.
  2. Run Trip Counts and FLOP analyses of the Characterization stage with the full data transfer analysis.
  3. Analyze data reuse and count the number of accesses to memory objects when modeling your application performance. 
$ advisor --collect=survey --static-instruction-mix --project-dir=./advi_results -- ./myApplication

$ advisor --collect=tripcounts --flop --data-transfer=full --project-dir=./advi_results -- ./myApplication
$ advisor --collect=projection --data-reuse-analysis --count-memory-objects-accesses --project-dir=./advi_results
