enforce-fallback

Emulate data distribution over stacks if stacks collection is disabled.

Syntax

--enforce-fallback
--no-enforce-fallback
Default
Off (no-enforce-fallback)
Actions Modified
collect
=projection
Usage
Use the
enforce-fallback
option to emulate data distribution over stacks after reducing collection overhead by removing
--stacks
option from Trip Counts collection (
--no-stacks
is default).
This may reduce analysis accuracy.
  1. Run Survey Analysis.
  2. Run Trip Counts and FLOP analyses without stacks collection.
  3. Model your application performance emulating data distribution over stacks.
$ advisor --collect=survey -stackwalk-mode=online --static-instruction-mix --project-dir=./advi -- myApplication
$ advisor --collect=tripcounts --flop --enable-data-transfer-analysis --target-device=gen11_gt2 --project-dir=./advi -- myApplication
$ advisor --collect=projection --enforce-fallback --project-dir=./advi
