Vtune won't show memory usage properly

[Allopis]

Hello, 

I'm trying to profile a program that is initiated by a script which spans a bunch of suprocesses. When analyzing hotspots vtune sees the cpu usage in our tool:

However if I run on the same program the memory consumption analysis only memory from standard linux tools is shown. (these are programs that are directly or indirectly called by the tool).  The real memory usage is higher, but it is not seen by vtune.

What could be the problem?

Hi,

Good day to you.

Thanks for posting in Intel Communities.

To assist you better, can you get back to us with the following information:

1. CPU details along with OS details and build number

2. Sample reproducer application/code to reproduce the issue from our side

3. Exact steps/commands that you used

4. VTune version

Thanks

1.

This is the cpu I'm using:

Model name: Intel(R) Xeon(R) Gold 6258R CPU @ 2.70GHz
Stepping: 7
CPU MHz: 2699.999
BogoMIPS: 5399.99
Hypervisor vendor: VMware
Virtualization type: full
L1d cache: 32K
L1i cache: 32K
L2 cache: 1024K
L3 cache: 39424K
NUMA node0 CPU(s): 0-7

It is a virtual machine in a VMWare environment

OS:

Red Hat Enterprise Linux Workstation release 7.8 (Maipo)

2.  The real code is very big and I cannot find a small example code that reproduces the problem

3. Make a project, run my program in memory consumption mode

4. VTune 2023.2.0.49485

Thanks in advance

Hi,

Thanks for your reply. 

To assist you better, we would need a sample reproducer, i.e., the application you're running(if you're not trying the in-built samples).

Could you please share the sample reproducer to check the issue from our side?

Thanks

Hi Rahila,

I tried creating a small reproducible test case but I couldn't manage unfortunately.

Hi,

For Community support we would require a minimum reproduction sample code specific to your issue that provides us with the most relevant background information for triaging your issue further. As you're having issue creating one, we have shared the procedure for uploading large files through private messages (Please note that this link expires in 24 hours)

In case you require privacy, and unable to share the issue / sample with us publicly, please submit a ticket for Priority support so that your application can be handled with the required data protection and privacy regulations.
