Usage
Dynamic instruction mix is counted for the entire execution of the application; static instruction mix is counted per iteration. The
static-instruction-mix
,
dynamic
, and
mix
 options work together in the following manner:
  • Collect static instruction mix data:
    --collect=survey --static-instruction-mix
    (In the GUI: Static instruction mix data is calculated on demand.)
  • Collect dynamic instruction mix data (and static instruction mix data, from which dynamic mix data is calculated):
    --collect=tripcounts --flop
  • Show static instruction mix data in a Survey report:
    --report=survey --mix --no-dynamic
  • Show dynamic mix instruction data in a Survey report:
    --report=survey --mix --dynamic
  • A Survey report cannot show both static and dynamic mix instruction data.
    (In the GUI:
    Code Analytics
     can show both static and dynamic instruction mix data.)
Enabling
static-instruction-mix
:
  • Is necessary in scenarios involving the Python* API.
  • Can increase finalization overhead.
Example
  1. Run a Survey analysis. Collect static instruction mix data.
  2. Generate a Survey report. Show static instruction mix data. 
$ advisor --collect=survey --static-instruction-mix --project-dir=./advi_results -- ./myApplication
$ advisor --report=survey --mix --no-dynamic --project-dir=./advi_results
