_init() instrumentation failed

I'm getting an instrumentation fault when I attempt to do a hotspot analysis. It is an evaluation copy and the binary was generated by a Go compiler. Does anyone have a clue why vtune is looking for queens_init() and what it wants to do with it? The only other possibly unrelated issue was that I had to remove my /etc/fuse.conf to work around an install seg fault but it is hard to imagine that is the problem.

Thanks in advance...

Error: [Instrumentation Engine]: Function IMG_FindByUnloadAddress called without holding lock


I have been profiling the same FORTRAN OpenMP code on 4 threads on a node comprising 2x 6-core Westmere, under the SGE batch system where I have reserved all 12 cores exclusively for my use.

Out of my 20 runs, I have one that failed with the following to standard error:

Vtune "named user license" on both windows and linux


I've read online that it is possible to use Vtune on muliple machines with a  "named user license".  Is this true for both Windows and Linux at the same time?  Can I use my "named user license" on both operating systems?

When I went to purchase Vtune I noticed there are two versions (Windows or Linux).  Both  have the same price.  So, I will I be locked to either Windows or Linux depending on which I purchase?   If a "named user license" can be used for both OSes, how do I get the application code for OS that I didn't originally purchase?

Finalizing results hangs with large .pdb file

I am experiencing an issue with Intel VTune Amplifier.

My executable has a rather large .pdb file (~390MB). After collecting data, the resolve step hangs while resolving symbols. I can fix the problem by removing un-referenced functions from the .exe and .pdb files (Visual Studio Linker option /OPT:REF). This shrinks the .pdb file to ~140MB and the .exe file from ~22MB to ~9MB.

Is this a known issue with V-Tune? Even with very small samples; V-Tune will hang if the symbol file is large.

Profile Failed

Hello,I profiled the sample project tachyon vc10, and got a problem.. B elow is the log:

VTune Data Collection automatically triggering prematurely


I am trying to perform Basic Hotspots analysis using VTune Amplifier XE 2015 on my win64 machine, and experiencing problems with VTune Data Collection log process triggering prematurely. 

This is my workflow. I click on the "Start" or "Start As Paused" (for Start/Resume workflow) button and am in the process of running a script in my application for profiling. However, after a few seconds VTune Data Collection Log is automatically getting triggered without my performing any other action in VTune (no "Pause" or "Stop"), and before my script is done running. 

collection failed: Internal Error


vtune was used to profile a process owned by root and failed to collect. Please see below for the screen capture.

OS is oracle linux server 6.5(2.6.32-431.el6.x86_64)

Intel(R) VTune(TM) Amplifier XE 2015 (build 367959)

Vtune Amplifier XE 2015 with "Error: Amplifier cannot detect Intel Xeon Phi coprocessor configuration"


I am using VTune? Amplifier XE 2015 to profile a large program running natively on Xeon Phi,unfortunately it fails in the first place.

Then I tried to build the sample application: Matrix included in Vtune Amplifer and copied the native binary matrix.mic to the mic0:/tmp.

Basically I followed the steps as shown in the link below:

Collection failed - [Instrumentation Engine]: SYSCALL_INSPECTOR:

for any kind of profiling, after my application finishes, I get:

[Instrumentation Engine]: SYSCALL_INSPECTOR: The
NTDLL!NtSetContextThread function jumps out of NTDLL, at 0x077960400.
It may be hooked by a PIN-incompatible software installed on the system
Incompatible operating system or incompatible software installed on the
system Pin is exiting due to fatal error

What can cause that?

Thanks, Marek.

Blue Screen during advanced hotspots analysis in attach-to-process mode


I saw a Windows blue screen during a VTune analysis for the second time now, so I decided to create a new post about this.

I did an advanced hotspots analysis in attach-to-process mode while 3 instances of my application were running. They were running already for nearly a day (I did a long-term test) before I attached to one of these (independent) instances (advising VTune to attach to a certain process ID). I set the evaluation interval to 10 ms (default), and configured to catch only user events instead of all.
