Error: PMU resources are not available.

Intel VTune Amplifier XE 2013

Windows 8 64 bits. VS 2010 & VS 2012. IvyBridge, i7, GT2.

when I try to run bandwidth - Sandy Bridge / Ivy Bridge analysis, I get this error:

Error: PMU resources are not available. Hardware Event-based Sampling is not supported on this operating system.

Then I checked driver status - here's what I got. In admin commandline of coz.

It seemed that drivers were installed correctly except vtss++, but it doesn't matter.

Was it possible one of below reasons? You may verify:

1.You may install Windows* 8 on Virtual Machine, the tool cannot access PMU resource?

2.You may install other tool, which already uses PMU resource? 

If none of above, you can try:

a. Open a cmd with administrator privilege 

b. C:\temp>"\Program Files (x86)\intel\VTune Amplifier XE 2013\amplxe-vars.bat"

Copyright (C) 2009-2013 Intel Corporation. All rights reserved.
Intel(R) VTune(TM) Amplifier XE 2013 (build 274450)

c. C:\temp>amplxe-cl -collect snb-bandwidth -duration 20

What happens?

[rohit_t_]

1 more possible reason is that you would have previously run vtune and its sampling session might be still going on in the background and when you again run vtune for new sampling session .

It will give this kind of error.

try killing the previous running session the rerun vtune

[Bernard]

It is quite possible explanation for the error.The question is does VTune can run multiple sampling sessions?

Only one PMU event-based sampling can run at a time. If you invoke PMU event-based sampling for another session, the tool will report error. However if you invoke user-mode sampling for another session - it is allowed.

If this standard WDM driver then I/O manager is responsible for calling driver entry function.Not going too deep you can at least monitor registry calls with regmon during the VTune session and look for driver related queries.

No other vtune session running, at least not I aware. How to confirm?

And it's running on physical machine, no VM.

here's result for amplxe-cl:

C:\Windows\system32>amplxe-cl -collect snb-bandwidth -duration 20
amplxe: Error: PMU resources are not available. Hardware Event-based Sampling is
not supported on this operating system.
amplxe: Internal Error

You can look at task manager or process explorer(process explorer is a better option) and look for the instances of VTune process.I do not know how exactly VTune session can be recognized , but i suppose that at least some thread will be created solely for this and you can track such a thread with process explorer.

Hi Peter

what is the purpose of vtss.sys driver?

that is the driver to capture call stack info when doing PMU event-based sampling collections.

[Bernard]

Could this driver loading and initialization failure be responsible for the error?

Failure of this driver can also explain the error message.

[Peter_W_Intel]

Loading vtss++ driver failure should not impact on PMU event-based sampling (without stack info in result). Not sure if the user worked on old XE 2013 version which might not support new silicon or new OS. Strongly suggest to try latest XE 2013 Update 6.

I agree with you.

All product registered users will receive a notice in their email box, when VTune(TM) Amplifier XE 2013 new update is ready. Also the user can view/get new package from Intel Register Center Download -

https://registrationcenter.intel.com/RegCenter/Download.aspx?productid=1686, for Windows*

https://registrationcenter.intel.com/RegCenter/Download.aspx?productid=1682, for Linux*

I'm using XE 2013 Update 5, will try update 6... Thanks!

[gabest]

I have the same problem, Win8 x64, i7-4770, vtune update8.

[Peter_W_Intel]

Latest build is Update 8. vtss+ driver failure will not impact on using Event-base sampling collection - again.

I strongly suggest to submit this problem to Intel Premier support with system info - "amplxe-feedback.exe -create-bug-report logfile" can generate log file for investigating.

[gabest]

No idea how to do that, email says there will be a link below the vtune download, but there is not.

"On the download page, click the "Click here for technical support" link below the Download Now button to start your 30 days of free support."

Maybe someone on the dev team should try to run it on Windows 8 x64 on a new Haswell and see? I know it is hard to move from XP.

[gabest]

More weird stuff is happening here. 

cpuid(7) => 0x281, it does not look like a valid answer, AVX2/BMI1/BMI2 flags aren't set, but the related new instructions execute just fine.

Attached a picture of CPU-Z.

[gabest]

Alright, here is what I figured out.

If you are developing for Windows Phone, the SDK enables the built-in Hypervisor of Windows 8. It blocks something for vtune to work with hardware events and it is not up-to-date enough to set the right cpuid feature bits if you want to detect Haswell.
