Why the CPU Usage differ between Basic Hotspots and Advanced Hotspots?

Two images: in the basic hotspots is what I was expecting (towards 400% utilization, the "4" cores used by threads). In the Advanced hotspots (not even 100% utilization), like only 1 core used.

In the Advanced, If I check the platform or bottom-up with threads/cores there is no overlapping, it just shows the same, like only 1 core is used. I don't specify any type of AFFINITY.

Hi Folks,

I'm working on profiling a third-party database server running on a single baremetal Skylake Xeon Platinum 8180 node running CentOS 7.2.  The server software is running as root user as well as the vtune command-line tool.  When using any preconfigured user sampling profile such as hotspots, VTune will not stop recording after the given duration.  In addition, my query benchmark running on a separate client machine runs well past its own time limits on execution.  At a certain point, the query rate just slows to a crawl and I cannot break out of amplxe-cl using Ctrl-C or its own stop command (that gives me an internal error).  Any advice is much appreciated.

-Marc

UPDATE:  Through some strange combination of *when* I start the benchmark, I'm able to capture some of the trace inside the GUI.  It finalizes results but the collection log shows:

Hi, I want to run an HPC analysis since our app is heavy FPU intensive.

Our setup is an OSX host, Parallels VM with Windows 10 insider preview guest running on an "Intel(R) Core(TM) Processor code name Penryn" with Frequency: 3.2 GHz and  Logical CPU Count: 2

The FPU intensive part is inside a DLL that is loaded dynamically by our EXE.

I'm getting an "FPU Utilization: Not supported for this CPU." message, which I don't understand. Any idea what to do to measure FPU utilization etc.?

I update VTune to 2018 update 1. It reports "Cannot enable Hardware Event-based Sampling due to a problem with the driver (sep*/sepdrv*). Check that the driver is running and the driver group is in the current user group list. See the "Sampling Drivers" help topic for further details."

my machine installs Windows 10

OS Name Microsoft Windows 10 Enterprise
Version 10.0.14393 Build 14393
 

I referred  to the help page, and run "amplxe-sepreg.exe -i". it fails with the following error message

I am trying to analyze 100 different types of pdfs in adobe reader , is there any way for batch analysis of those files one after the other.Thank You.

The results are generated by the following structure.

How to convert it to CSV or any other available format through the command line.

Hello All,

I was wondering if there is a way from the command line to group the results by synchronization event. By synchronization event I mean each time a synchronization was called. For example, if the same barrier wait is called multiple times, I would like to see stats for each of these times individually.

Thank you very much in advance

I have created a simple C++ app called timeWaster. Built it using MSVC  19. This app runs fine in a command window created by Parallel Studio. (compiled using cl -EHsc -Zi timeWaster.cpp)

Sample run:

D:\Users\...\VTune\timeWaster>timeWaster64.exe

a=3.21061e+006

primeCnt=348844

11.2066  seconds

Done

Launch Vtune with admin rights.

Go to configure, select “Launch Application”, browse to the timeWaster64.exe, set working dir to same.

Toggle over to the run screen, “Basic Hotspots” selected, everything set to default. Hit start …

Up pops a command window … that stays empty (this window sticks around till killed with task master, timeWaster process still running 0% cpu).

Then within seconds of hitting start:

Intel VTune Amplifier XE 2017 has faced a serious problem

Error 0x40000024 (No data) -- No data is collected. Possible reasons:

 - Workload is too small. No samples are collected.

 - The application environment is not specified correctly.

 See the Troubleshooting help topic for more details. 

Trouble shooting area of of no help so I am here.

So where do I start tracking this down? I have already considered dll dependencies and pruned that list down to a minimum.

Hello VTune Users,

With constant interest to OpenMP parallel efficiently analysis and growing popularity of VTune Amplifier Performance Analysis Cookbook we added a recipe that explains how to detect OpenMP imbalance on barriers and scheduling overhead based on a use case with prime numbers calculation: https://software.intel.com/en-us/vtune-amplifier-cookbook-openmp-imbalance-and-scheduling-overhead. 

It would be great to hear your feedback on the article usefulness, format convenience and what we can do more to make OpenMP analysis in VTune Amplifier better.

Thank you, Regards, Dmitry

Hi,

In our internal linux distribution based on "Debian testing" I get a complete system crash when starting a profiling session (even if the command being profiled is as simple as a "/bin/ls"). As a starting point, hoping that this issue is not exclusive to our internal distro, can anyone please confirm whether VTune works in "debian testing"?

This is with VTune Amplifier 2018 Update 1 (build 535340):

1- Run VTune and press "New Project" toolbar button.
2- Set "target type" to "launch application", and "Application" to "/bin/ls".
3- Press "Choose Analysis" button on the right
4- Choose "Advanced Hotspots" analysis (I haven't tried other modes yet)
5- Press "Start" button on the right.

Result: the system crashes completely.

Thanks,
Ricardo

- vtune (20128 u1) in visual studio 2017 (all updates applied as of today)

- in visual studio, have vtune profile the executable (which is built by the open solution)

- after that finishes, attempt to launch the executable in the vs debugger

-> screen goes back and the machine restarts. There are no errors in the system event log or a code dump file for the system (according to our IT guy).

Any ideas? This is the only time the machine has crashes recently. Happened 2x with the above workflow.

Thanks.

Will this error produce some unwanted results ? if yes how to fix it .

Thank You

I am using VTune 2018 update 1 and when running my application via VTune it crashes immediately at startup. I also tried executing vtune via command line: amplxe-cl -c hotspots application.exe

I also tried attaching VTune to a running process and that goes fine until application shutdown, than VTune seems to think its a crash and loses all profiling information. If i collect profiling information before shutdown the results look good.

Its a 32 bit process  on windows 10 (delphi) which run's C++ code.

Any tips for investigation or possible causes?

Dear forum,

we recently ran into a problem with Intel VTune™ Amplifier 2018 update 1:

• Win 10 1703: Failing to start VTSS driver: error 0xfffffffa on "net start vtss"
• Win 10 1709: BSOD when starting the VTSS driver

After quite a lot of troubleshooting we narrowed the problem down to the following:

• Together with rolling out Win 10 in the company, our IT department decided to increase security by activating Windows Defender Device Guard
• If I take away the respective registry keys, everything runs as expected again.

Now our questions:

• Is there already a version of VTSS (maybe also beta) that is compatible with device guard
• When will there be an officially released version of VTune / VTSS fully compatible with Defender Device Guard
• Are there known workarounds for the problem other than deactivation of Device Guard?

Thanks a lot for your help in advance and best wishes,
Brainlab Team

Has anyone gotten an Open Source non-commercial license for VTune (Parallel Studio XE) lately, e.g., following this process:

https://software.intel.com/en-us/qualify-for-free-software/opensourcecon...

That is, within the last couple of months or so?

It worked flawlessly for me a year ago, but this time there has been zero response despite the following "confirmation" message in registrationcenter:

Please check your email for instructions to download your product. Note that this may take up to two business days.

that was six weeks ago and I've been kind of chasing my tail with support. Trying to figure out if this is affecting other non-commercial users or "just me".

I mostly use this pacakge so I can support the icc compiler in addition to the other major compilers, but I'm starting to question my commitment. Some more details on my ICC thread.

Hello

I want to profile my application on Intel Xeon-Phi co-processor using Intel Vtune Amplifier 2018. I am using the following command : 

amplxe-cl -target-system:mic-native:mic0 -collect-with runsa -knob event-config=?

to get all the PMU events for xeon-phi, but I am getting the following error :

amplxe: Error: FailedTo Read Content Definition(mic-native)

The xeon-phi card(mic0) is working.

What is the issue here?

I'm evaulating VTUNE but I ran into a problem.

You may need to build vtsspp driver for your kernel.
Please see the vtsspp driver README for instructions.

After patching our OS for Meltdown we're seeing nodes crash during amplxe-cl collection using the HW counters (any of the non-PIN collections)

PIN collections work ( simple hotspots )

Also, using the older 2017 Update 1 VTune and collectors there are no issues.

But 2018 Update 1 with event counters crashes the node almost immediately after start of collection on any application. 

SEP drivers were not rebuilt after the Meltdown kernel patches - perhaps that is a test to do?

Anyone else seen this behavior?  Nodes crash hard and have to be power cycled.
