Can we create a new analysis type with VTune Amplifier XE command line interface

[yeyangever]

Hello everyone,

I am running VTune Amplifier XE in command line. I wanted to use the "hardware event based sampling" to see the number of specific hardware events.

But there's only 4 build-in "hardware event based" analysis types:

nehalem_general-exploration

nehalem_cycles-uops

nehalem_frontend-investigation

nehalem_memory-access

But running four of these analysis, I cannot get the exact event I want to see. In GUI, there's configuration panel for you to "create a new analysis type" and select precisely the kind of events you want to include. But for command line, I cannot find correspond options to do so from the online document:

http://software.intel.com/sites/products/documentation/hpc/amplifierxe/en-us/lin/ug_docs/index.htm

Can anyone tell me how to do it? Thank you!

Hello,

See my example: use example application from the product

1.export PATH=$PATH:/opt/intel/vtune_amplifier_xe_2011/bin64
2. cd /opt/intel/vtune_amplifier_xe_2011/sepdk/src/
3. ./build-driver
4../insmod-sep3
5.amplxe-cl -collect-list ; findpredefinedanalysis "nehalem_memory-access", which includes more events
6. cd /opt/intel/vtune_amplifier_xe_2011/samples/en
7.amplxe-cl -collect nehalem_memory-access -r r0006ma -- ./tachyon_analyze_locks
8.amplxe-cl -report pmu-events -r r0006ma -group-by function -filter module=tachyon_analyze_locks

All event should be displayed from outputs. Note that all related events are wrapped and showed as Analysis Type. Absolutely the user can see events from GUI, or define their favorite eventsto crearea new Analysis Type.

Regards, Peter

Hey Peter,

Thank you for the respond. According to your explanation, there seems no way to customer analysis types in command line (I haven't find it either). But I have tried four buit-in hw-events based analysis types, I found there are many less events listed by them than that is supported.

My processor is 32nm Xeon processor, therere totally around 100 events supported by these 4 analysis types I haven't take time to find duplication). But according to the online "Reference for Processor Events", there're many more. And actually I cannot find a lot of them from the result of the 4 analysis, for instance (just a random instance):

the group of:

L1D.PERL

L1D.M_PERL

L1D.M_EVICT

L1D.SNOOP_EVICT

I cannot find them.

Could you help telling if there is a way to make it work? Thank you!

There is currently no way to create a new analysis type from the command line. However, new analysis types created in the GUI can be used from the command line.

Use -collect-list to see the analysis types, including ones created from the GUI.

This is exact story as Mark described above. Thanks Mark!

Hi, yeyangever

I think that Peter has already answered your question.

you could create a new analysis type in the GUI mode, and then use it in the command-line mode.

I mean you could create a new analysis type such as named "cpu clk break". And you could add events which you are interesting in this new analysis type. Then you can switch to the command-line mode. Runamplxe-cl --collect-list command. You will see that the new analysis type "cpu clk break" is there. And you could use this type same as the predefined types.
