collect-with

Run a hardware event-based, or user-mode, collection using your settings.

Syntax

-collect-with <collector_name>

Arguments

collector_name

Description

runsa

Perform hardware event-based sampling collection.

runsa-knc

Perform user mode or hardware event-based sampling collection on Intel Platform Code Name Knights Corner.

runss

Perform user-mode sampling and tracing collection.

Description

Use the collect-with action when you want finer control over analysis settings than the collect action can offer. Specify both the collector type and the knob. The collector type determines the type of collection, and the knob determines the level or granularity. Lower levels are coarser grained, while higher levels are finer grained. The analysis process includes finalization of the result, and a summary report is displayed by default.

For the runsa (event-based sampling) collector, the event-config option specifies the list of events to collect.

Note

  • To access the most current command line documentation for the collect or collect-with action, enter amplxe-cl -help collect or amplxe-cl -help collect-with.

  • For the most current information on available knobs, enter amplxe-cl -help collect <analysis_type> or amplxe-cl -help collect-with <analysis_type>, where <analysis_type> is the type of analysis you wish to perform.

Alternate Options

Use the collect action with predefined settings.

Example

This example runs the hardware event-based sampling collector for the sample.exe application on the specified events and displays a summary report.

$ amplxe-cl -collect-with runsa -knob event-config=CPU_CLK_UNHALTED.CORE,CPU_CLK_UNHALTED.REF,INST_RETIRED.ANY C:\test\sample.exe
