How to count the PMU events using nsys CLI?

[chongxiao_li]

Hello! I am new to the nsight system.

I am trying to use the nsys CLI to count PMU events such as “L1 Data cache access” when running an application on AGX Xavier. I use the following command:

sudo nsys profile --stats true --cpu-core-events='0x13' ./TEST

But I can’t find the counting result of the event ‘0x13’ in the report. Where can I find it?

Thanks in advance.

Hi,

Have you checked it with the Nsight System UI tool on the host?
We can find some memory events with it.

$ cd /usr/local/cuda-10.2/samples/0_Simple/matrixMul
$ sudo make
$ sudo nsys profile --cpu-core-events=0x01,0x08,0x11,0x13 ./matrixMul

Thanks.

Thank you for your reply!

But I want to know the exact number of the events counting. Where can I find this information?

Thanks!

The --stats option only gives a generic set of stats to the screen, and that set does not include GPU markers.

We also have a post run option “nsys stats” that can give more options for getting data, but I do not believe that the GPU markers are being export currently. @jkreibich to confirm.

No, I don’t believe we export that data. Even if we do, I don’t believe we have an existing stats report that will display it.
