同collect 后面的。

This example runs the hardware event-based sampling collector for the
sample application and displays the default summary report.

$ amplxe-cl -collect-with runsa -knob event-config=CPU_CLK_UNHALTED.CORE,CPU_CLK_UNHALTED.REF,INST_RETIRED.ANYhome/test/sample

比较常用的命令

collect

collect-with

event-config
knob
$ amplxe-cl -collect-with runsa -knob event-config=CPU_CLK_UNHALTED.CORE,CPU_CLK_UNHALTED.REF,INST_RETIRED.ANYhome/test/sample

查看报告时比较特殊

$amplxe-cl -report sfdump -result-dir r000rs

Currently, the only way to view the sample-after values is to display the results of a run with the default values using the 'sfdump' report type, e.g.,

sudo amplxe-cl -collect-with runsa -knob event-config=UOPS_EXECUTED.PORT2_CORE:sa=1000,UOPS_EXECUTED.PORT3_CORE:sa=1000,UOPS_EXECUTED.PORT4_CORE:sa=1000 -- ./driver

以我的经验，sa>=1000,否则机器容易跑死。

我设了100,1，死了2次。

$ amplxe-cl -report hw-events -r r010runsa/

这个report 类型对于原生事件查看结果比较好

This option enables multiple runs to achieve more precise results for hardware event-based collections.

When disabled, the collector uses event multiplexing.

sudo amplxe-cl -collect-with runsa -knob event-config=UOPS_EXECUTED.PORT2_CORE,UOPS_EXECUTED.PORT3_CORE,UOPS_EXECUTED.PORT4_CORE -- ./dr iver

用了 之后，不能跑第二次。

测的结果不太准啊， 郁闷。。。

不知道为什么，一定要学好architecture system and os system.

找出原因来。
