Emulate data distribution over stacks if stacks collection is disabled.

Off (no-enforce-fallback)
collect=projection
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.
Run Survey Analysis.
Run Trip Counts and FLOP analyses without stacks collection.
Model your application performance emulating data distribution over stacks.
