VTune 2023.0.0 crashed everytime when using user-mode sampling

[g199209]

Crashed everytime when using user-mode sampling in hotspots analysis. Memory consumption analysis also crashed.

Local Machine: macOS

Target: Remote Linux (SSH)

The `vtune-worker --type=result` command crashed, when trying to loading `xxx.pytrace` file:

I have tried 2023.1.0, also crashed.

Performance Snapshot, hardware event-based sampling in hotspots analysis and microarchitecture exploration work well.

Hi, 

The Intel VTune GUI is not supported on M1/M2 CPUs, only on x86 CPUs.

A workaround is to run the VTune server (backend) and open a browser from the Mac to the system running the VTune server.

Port Forwarding in Servers:

If you have a web browser on your host machine, you can follow the below process.

Note: VPN must be disconnected while doing port forwarding in servers

Step 1: To connect to a remote server, we use "ssh user_name@<IP_address of that server>"

Since we need to port forward from our local host to the remote server, we use the below command.

ssh -L localhost:<port_number>:localhost:<port_number> <server_username@server_ipaddress>
Eg: ssh -L localhost:8080:localhost:8080 sdp@10.165.154.190

Step 2: Source the variables.

 source /opt/intel/oneapi/setvars.sh

Step 3: Let us try to open the GUI of Vtune

vtune-backend --web-port 8080 --allow-remote-access --enable-server-profiling

Step 4: After running the above command, you can see two links are generated. Copy any one of the GUI links (Note: do not press ctrl+C) and open it in any of your browsers.

Step 5: Click on “Advanced” and proceed and set the passphrase. 

The passphrase should contain:

* A special character

* Any capital alphabet

* The length of the passphrase should be a minimum of 8 characters.

Vtune can now be accessed from a browser and you can do the respective analysis. 

If this resolves your issue, make sure to accept this as a solution. This would help others with similar issues.

Thanks and Regards,
