System wide Hardware Event-based Sampling (EBS) analysis is not available on the system

Hi,

I am trying to install Intel ParallelStudio 2015 on Ubuntu 14.04 without root (only installed for a single user). I get the following error message during installation:

Missing optional prerequisites
-- System wide Hardware Event-based Sampling (EBS) analysis is not available on
the system.


Here's the output from cat /proc/cpuinfo for the first processor

Any ideas what might be going on here? This processor should support EBS.

 

Thanks!

Hi John.

That's correct!  If you don't have root access, the installer can't load the hardware driver module needed to take hardware samples.  Thus, you are limited to software-based sampling, e.g., basic hotspots, concurrency, and locks and waits.

Thank you for the help, MrAnderson.

 

I've now run into another issue. I get the message:

Missing optional prerequisites
-- 32-bit libraries not found


I am installing on Ubuntu 14.04, which has deprecated the 32 bit libraries. Is it safe to continue and ignore this message, or should I install the 32 bit libraries?

 

Thanks!

Yes, you can ignore it.

Hello,

Let me note that w/o driver installation PMU-based collection will be still available through perf (Ubuntu 14.04 allows to do this). The point is that it 2015 Gold had some limitations on this.

I would recommend to install the latest Update 2 of VTune Amplifier XE where in driverless mode system wide and stack sampling are available. Please note that uncore events (and hence bandwidth analysis that is based on them) are still not available for this mode yet.

Thansk & Regards, Dmitry
