vtune community edition not working for skylake

Hi,

 I just downloaded and installed the free version of vtune on my skylake based server. I want to profile the CPU utilizatio for my workloads. Below is error log i m  getting when verifying the installation which suggest that there may be an issue with support for Skylake. Can you please confirm what may be the issue. 

Here are the cpu details.

CPU family:            6
Model:                 85
Model name:            Intel Xeon Processor (Skylake, IBRS)

Thanks,

Amar

Hello, Amar,

Can you clarify on what OS you run analysis?

VTune Amplifier Self Check Utility should provide you path to logs in case of some failures.

Log location: path

Can you send content of log or attach log file?

And you can try to reinstall Vune because it may be a problem with installation.

 

Regards,

Danil

Thanks for your prompt response Danil.

Below is error log.  Attached is the full log file. Any help is highly appreciated.

I tried reinstalling but it did not help.

Regards,

Amar

Looks like problem in getting Hypervisor name. Do you know the name of Hypervisor that you use? One of the possibilities to get it: run "cat /sys/hypervisor/type"

Hi Amar,

It looks like your system is running under hypervisor which isn't defining CPUID value properly. This confuses VTune and it can't proceed, unfortunately. It looks like your "/sys/hypervisor/type" is empty which is also OK for some hypervisors.

Also, it looks like hypervisor doesn't virtualize PMU - so, you would not be able to use hardware based sampling. This might be configured in the hypervisor.
