Syntax

--trip-counts
--no-trip-counts
Default
On (trip-counts)
Actions Modified
collect
=tripcounts
Usage
Use the option, which allows you to dynamically identify the number of times loops are invoked and executed, to:
  • Detect loops with too-small trip counts and trip counts that are not a multiple of vector length.
  • Analyze parallelism granularity more deeply.
Disabling can decrease analysis overhead.
Example
Run a Trip Counts & FLOP analysis. Collect trip counts, FLOP, and call stack data. 
$ advisor --collect=tripcounts --flop --stacks --project-dir=./advi -- ./bin/myApplication
Run a Trip Counts & FLOP analysis. Collect only FLOP data. 
$ advisor --collect=tripcounts --no-trip-counts --project-dir=./advi --search-dir src:=./src -- ./bin/myApplication
