Old VTune can display function name in hotspot analysis, but new VTune cannot. [C#][.Net]

HKR — Wed, 26 Jan 2022 10:46:32 GMT

I'm migrating development environment. I find recent VTune cannot work.

In the old environment, VTune can display function names in my codes with "Managed code profiling mode" = Managed.

However, in the new environment, VTune cannot show function names with the same codes and "Managed code profiling mode" = Managed.

I googled and found I may need to generate native PDB using ngen.exe. Then, I'm facing a few problems.

- I don't understand why the old environment can show function names.

- Though ngen.exe needs administrative privileges. I don't have administrative privileges.

Questions

1. How can VTune work well?

2. Why does the old VTune work well?

My environment is as follows.

My source codes

- Mixed with C# and C++

- Main: C#. C++ codes are called in C# codes.

- .Net Framework 4.5.2

Old environment

- Win7

- VS2013

- Intel VTune Amplifier XE 2015 Update 4

New environment

- Win10

- VS2019

- Intel VTune Profiler 2021

Hi,

Thanks for posting in Intel Communities. We looked into your case. We tried reproducing your issue from our end. We are able to see the function names in the Vtune after doing the analysis (both in standalone VTune and part of Visual Studio configuration of VTune) with the following configurations of the System and the Software:

Windows 10 OS
Visual Studio 2019
VTune 2022.0.0
With Managed code profiling mode = Managed

Could you please try updating your VTune to the version which is 2022.0.0.

Hope this help.

Rahul

Hi Rahul,

Thank you so much for your response.

Unfortunately, I can't try the newer version due to the slowness of the software installation procedure in my office.

I'll try the newer version maybe next month.

I'm ok to close this post.

Thanks,

HKR
