Description

When you configure a customHardware Event-based Sampling Collection, you may reduce the collection overhead and limit the stack size (in bytes) processed by the VTune Amplifier by using the -stack-size option.

Example

This example configures and runs a custom event-based sampling data collection with the stack size limited to 8192 bytes:

$ amplxe-cl -collect-with runsa -knob enable-stack-collection=true -knob stack-size=8192 -knob enable-call-counts=true -knob event-config=CPU_CLK_UNHALTED.REF_TSC:sa=1800000,CPU_CLK_UNHALTED.THREAD:sa=1800000,INST_RETIRED.ANY:sa=1800000 -app-working-dir
