Analyze potential data reuse between code regions.

Syntax
--data-reuse-analysis --no-data-reuse-analysis |
Default
Off (no-data-reuse-analysis)
Actions Modified
collect=offload
collect=tripcounts --enable-data-transfer-analysis
collect=projection
Usage
With collect=offload, this option automatically applies the data-reuse-analysis option to all analyses it runs.
With collect=tripcounts and collect=projeciton, use as one of the following:
- Use the full data transfer with collect=tripcounts and specify data-reuse-analysis only for collect=projection:
advisor --collect=tripcounts --flop --data-transfer=full --project-dir=<project-dir> -- <target-application>
advisor --collect=projection --data-reuse-analysis --project-dir=<project-dir>
- Enable the basic data transfer analysis with collect=tripcounts and specify data-reuse-analysis for both collect=tripcounts and collect=projection:
advisor --collect=tripcounts --flop --enable-data-transfer-analysis--data-reuse-analysis --project-dir=<project-dir> -- <target-application>
advisor --collect=projection --data-reuse-analysis --project-dir=<project-dir>
Example
Run the Offload Modeling with data reuse analysis using a collection preset.
advisor --collect=offload --data-reuse-analysis --project-dir=./advi_results
With the full data transfer analysis:
Run the Survey analysis.
Run Trip Counts and FLOP analyses of the Characterization stage with the full data transfer analysis.
Analyze data reuse 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 --project-dir=./advi_results
