Hello,

I'm running VTune Amplifier 2018, and I found what looks like a bug in the way command lines are managed.  Specifically, if the command line arguments of an application contain the ampersand character (even if the arguments are quoted), upon stopping the Analysis the GUI will show a "Please wait until the collection is cancelled" dialog box and the GUI will hang until doing a Force Quit.

I'm running the OSX version of the VTune GUI, connected over SSH to a Linux host.  The following command works fine:

/home/user/ffmpeg 'udp://192.168.1.5?overrun_nonfatal=1' foo.ts

but this command causes the GUI to hang:

/home/user/ffmpeg 'udp://192.168.1.5?overrun_nonfatal=1&fifo_size=5000' foo.ts

I've tried using both single and double quotes, as well as just having VTune run a shell script rather than putting the arguments directly into the VTune GUI.  The problem occurs in all instances.

Any suggests that could be offered to work around this behavior is appreciated.

Thanks,

Devin Heitmueller

Yesterday, we installed the Sampling Driver for Vtune Amplifier.

Whenever I run the memory access, all users on team server receive following message:

Hello,

Could anybody clarify what does such assertions from vtune logs mean?

25788 : CRITICAL : Assertion failed: pytrace_collector710: thread_manager_result == tpss_thread_manager_op_err_ok || thread_manager_result == tpss_thread_manager_op_err_acquired : Cannot acquire tsd for current thread (tid = 25788), result = 8. Please contact the technical support.

I'm trying to profile a .NET Core 2.0 application on Linux using VTune as described on https://blogs.msdn.microsoft.com/dotnet/2017/10/23/net-core-performance-... The profiler runs, but when I view the results none of my .NET Core assemblies are shown and instead most of the time is spent in "[Outside any known module]":

When I run the same binaries on Windows I get method names in top-down view:

I'm running VTune Amplifier 2018 Update 3 on Windows 7 x64 and Ubuntu 16.04 x64. The Ubuntu machine is a VM running in Virtual Box.

Windows command line: "C:\Program Files (x86)\IntelSWTools\VTune Amplifier 2018\bin64\amplxe-cl.exe" -collect hotspots -mrte-mode managed -- dotnet My.dll

Linux commands: 

sudo -i
source /opt/intel/vtune_amplifier/amplxe-vars.sh
echo 0 | sudo tee /proc/sys/kernel/watchdog >/dev/null
echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope >/dev/null
echo 0 | sudo tee /proc/sys/kernel/kptr_restrict >/dev/null
amplxe-cl -collect hotspots -mrte-mode managed -run-pass-thru=--no-altstack -r ~/vtune/out -- My.dll

The "-run-pass-thru=--no-altstack" is to suppress the following error: "amplxe: Error: Stack size provided to sigaltstack is too small. Please increase the stack size to 64K minimum." I don't know if that's related to the problem or not.

How do I get it to show the method names on Linux?

I am using Intel VTune Amplifier 2018 with update 3 on **Windows 7**.

I performed Advanced Hotspot Analysis on my application with Hotspots, call counts and stacks. However I can't seem to find the estimated call count metric anywhere. Which view shows it? I have tried looking inside the Hotspots viewpoint (under Bottom-up, caller/callee etc.) to no avail.

Hi All!

I'm trying to track down Intel Vtune 2018 Version 3 for my organisation. We have a paid subscription.

If anyone could help that would be terrific.

Thanks

Hi,

My company bought vTune Amplifier. I can use XE 2016 Update 2.

And I want to register this product, where can I find the serial number? 

Hey all,

Does anyone know how to convert a .tb file to a .csv file? I'm importing my sep results into Vtunes and want to visualize the hardware event count of software with different workloads on the same graph. I've looked around and it looks like Vtunes doesn't create graphs like that so I want to know how to convert my .tb files to .csv.

Thanks!

When trying to do hotspot analysis I am getting error message saying "Cannot enable advanced capabilities for Hardware Event-based Sampling: problem with the driver (vtss/vtsspp).

I installed the drivers:

Hi,

I'm trying to analyze the performance of a hybrid MPI & OpenMP code using intel vtune. I'm compiling my code using intel/18.0.2 & impi/18.0.2 & vtune/18.0.2 The OS is rhel 3.10.0-693.17.1.el7.x86_64 and CPU's are Intel Xeon Platinum 8160 (Skylake). I compile my code using "mpicc -xCORE-AVX512 -qopenmp mycode.c -g -O3" (I tried -O0 but didn't help), and I submit the code using "amplxe-cl -collect hpc-performance -r r000hpc ./a.out"

The code doesn't run at all and just jumps out (without vtune it runs without any problem). I get the following error message:

Hello everybody,

I'm not an expert so i already apologies if i'm doing an obvious mistake.

I try to analyse the performance of a programm for different compilation method's.

So i tried to do a profile-guided optimization with intel's compiler (following this tutorial : https://software.intel.com/en-us/code-samples/intel-compiler/intel-compi... ) and the performance worsted. I then tried to launch a vTune analysis (advanced-hotspot) to see what happend but it never ended-up.

When i launch the programm without vTune he run perfectly, but with vtune the processors doesn't even start.

Of course i've waited for a longer period it's just for the screenshot.

Here is how i compiled the programm :

icpc sources/minimax_graph.cpp -std=c++11 -prof-dir=../bin -prof-gen -O3 -o test.out                           # bin is a directory where is stored the profile generated, originially the compiled programm are stored in this folder

cat ../input/j2.txt | ./../bin/intel_profil_O3.out                        # generate the profile

icpc sources/minimax_graph.cpp -std=c++11 -prof-dir=../bin -prof-use -O3 -o test.out                              # compil and use the profil

If you want the source code, here he is : https://raw.githubusercontent.com/ingambe/ter/master/sources/minimax_gra... (is .h file is here : https://raw.githubusercontent.com/ingambe/ter/master/sources/minimax_gra... )

the vtune command is the following : amplxe-cl -collect advanced-hotspots ./test.out < input/j1.txt

I've added to path Intel compiler and vtune using :

source /opt/intel/compilers_and_libraries/linux/bin/compilervars.sh intel64 and source /opt/intel/parallel_studio_xe_2018/psxevars.sh intel64

I have an intel processor (i7-4710HQ), i use Ubuntu 18, here is the result of the uname -a command :

Linux pierre-PC 4.15.0-24-generic #26-Ubuntu SMP Wed Jun 13 08:44:47 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

I've reboot my computer but i still have this issue.

Here is the result of : icpc --version

Thank for the help,

Have a good day ! :)

Hello,

I want to analyze hotspots for a program but vtune2018 outputs "out of memory" and some assertion fail(after a period time of execution). But actually, memory is far away of exhaustion. Its output is as following

Hi, Intel support staff,

I am applying Intel 2018 Amplifier to our Intel Fortran application codes to diagnose nested do-loops. These nested do-loops cost too much time and amplifier shows that LLC miss count # is very huge. All tests with Amplifier are done on a 2-socket Skylake Dell computer with L1 cache: 2.5MB, L2 cache: 40MB and L3 cache: 55MB and DRAM 191GB.

I found the following information on the Intel Website:

Metric Description

The LLC (last-level cache) is the last, and longest-latency, level in the memory hierarchy before main memory (DRAM). Any memory requests missing here must be serviced by local or remote DRAM, with significant latency. The LLC Miss metric shows a ratio of cycles with outstanding LLC misses to all cycles.

Possible Issues

A high number of CPU cycles is being spent waiting for LLC load misses to be serviced. Possible optimizations are to reduce data working set size, improve data access locality, blocking and consuming data in chunks that fit in the LLC, or better exploit hardware prefetchers. Consider using software prefetchers but they can increase latency by interfering with normal loads, and can increase pressure on the memory system.

In order to either reduce the LLC Miss Count # or completely eliminate it, could you tell me any suggestions on how to revise our nested do-loops which are written with Intel Fortran?  I look forward to your help. Thanks in advance.

If you need our test codes, I may upload them on demand.

Best regards,

Dingjun

Hi,

    I am using 2018 Version 3 of Vtune Amplifier.  I have a remote system with a process that I want to attach to and instrument.  When I use Hot Spot or Advanced Hot Spot, what I see is that I can collect data, and the results get returned in a reasonable fashion.  But when I try to use Locks and Waits, I can see the data being collected in the temporary directory, but it never completes and it never returns to the GUI.  If I press "stop", the gui just sits there, and the data continues to be collected on the remote system.  If I kill it manually, the data is apparently corrupted (or I don't know how to manually pull it off the device and into the GUI).  Has anyone seen that this never completes, or know why this might be the case?  I can't use the Locks and Waits functionality at all at this point.  The target device is running Ubuntu 14.04 Linux, and I am accessing it by SSH.  The process that I am instrumenting is a long-running daemon that I attach to remotely.

    Any help would be appreciated.

Thanks,

Gary

hello,

Is it possible to extraction memory traces information along instruction count from intel vtune? If yes, can you please give me idea how to perform this operation.

Cannot locate debugging information for file `/usr/local/caffe2/lib/libcaffe2.so'.

When run a simple test code (just main) which is not linked against anything, the source code is visible.

Any hints would help.

Thank you,

Is there a way to use VTune to do a roofline analysis on a Python script?

Thanks.

Hello,

I need to profile a software using

-Software sampling

-Locks and waits analysis (looking at multiple threads)

I am from the dark side and bought a Threadripper 16 core processor (did not know that I would want to use vtune on it), so I am wondering if I can use VTUNE for that? According to wikipedia software sampling works, but I am not sure about Locks and Waits analysis.

Greetings,

Christoph
