Hi,
I am trying to use AMDuProfPcm to collect metrics for my application. I was able to install the AMDuProf successfully on my Ubuntu 22.04 system following the instructions in the user guide. However, I cannot launch any application using AMDuProfPcm. There are two types of errors: "Fail to execute with execvp" and "Error: Invalid Launch application path" (two examples and some info about my system are attached below). Unfortunately, I cannot find any relevant information in the user guide. Has anyone seen these error messages before? Thank you!
Example 1:
root@node0:/opt/AMDuProf_4.0-341# bin/AMDuProfPcm -m ipc -- sleep 1
Error: Invalid Launch application path : sleep
Example 2:
root@node0:/opt/AMDuProf_4.0-341# bin/AMDuProfPcm -m ipc -- Examples/AMDTClassicMatMul/bin/AMDTClassicMatMul-bin

Hello, for both issues you reported, can you please try using absolute path for the executable you are trying to profile?
AMDuProfPcm -m ipc -- `which sleep` 1
bin/AMDuProfPcm -m ipc -- $PWD/Examples/AMDTClassicMatMul/bin/AMDTClassicMatMul-bin
Regards,
Santosh
Hi Santosh,
Sorry for the late reply. I didn't get a notification of your message.
I can confirm that absolute paths work properly in both cases.
Thanks,
Yilong
So I assume this is a bug?
Hi yilong,
This is not a bug really - but i have filed a bug report / feature request to either allow users to specify relative path or document the requirement of absolute path in the user guide.
Hi, this issue has been fixed in our latest release of uProf 4.1. Please visit AMD μProf | AMD for details.
