stack-access-granularity

Specify stack access size to set stack memory access measurement granularity for the data transfer simulation.

Syntax

--stack-access-granularity
=
<integer>
Arguments
<integer>
 is a power-of-two value from 16 to 1048576.
Default
1048576
Actions Modified
collect
=tripcounts --data-transfer=[medium | full]
collect
=tripcounts --enable-data-transfer-analysis --track-stack-accesses
Usage
Decrease the stack access granularity if your application has multiple small objects on a stack to improve analysis accuracy. Decreasing the granularity increases collection overhead.
Example
Run the Trip Counts analysis with medium data transfer and decrease the stack access size to 32: 
advisor --collect=tripcounts --data-transfer=medium --stack-access-granularity=16 --project-dir=./advi_results -- ./myApplication
