vtune amplifier memory analysis causing hard reboot on linux

[emmanuel1]

Hello,

I'm using vtune_amplifier_xe_2017.3.0.510739

on CentOS 7.6.1810

with processor Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz

on a simple test C++ program int main() { int s = 0; for(int i = 0; i < 1000; i++) { s += i; } printf("%d\n", s); }

I launch amplxe-gui with environment variable AMPLXE_MORE_PIN_OPTION='-ifeellucky', and nmi_watchdog disabled.

Then, a few seconds after launching the Memory Access Analysis tool, the screen turns black and the computer reboots.

Any idea?

Hey emmanuel1,

The version of vtune you use seems to be old/outdated, which might be causing the issue. Could you please try downloading the latest vtune version and try your experiment again. You can download latest version of vtune from the below Link for free.

Intel VTune Profiler

Please let us know if you are facing any issues with the latest version

Thanks

Hello & thanks for your suggestion.

We updated and tried vtune_amplifier_xe_2017.6.0.554757

The result is the same.

Perhaps that is not the latest version?

Hi.

The last version is 2020 update 3. You have 2017 major version, I think it was 3 years ago
