Vtune 2015 Update 2 stopped working on some VS2010 solutions

Hi,

I've just upgraded to Update 2 (from update 1) running inside VS2010.  On some C++ solutions I'm finding the New Analysis and Project properties greyed out and I can run any analysis on those projects.  The solutions still have the the results files from the previous version and I can open those fine.  On other solutions I've checked the New Analysis button isn't greyed out and I can run those without problem.

administrative privileges issue when using VTune Amplifier

Hi,

            I  am trying to use VTune Amplifier with demo project tachyon_vtune_amp_xe.zip in C:\Program Files (x86)\Intel\VTune Amplifier XE 2015\samples\en\C++, but not sure why it reports below issue, so look for help here

             It says:  Collection failed.The data cannot be displayed.  Highly accurate CPU time collection is disabled for this analysis.To enable this feature, run the product with the administrative privileges.  [Instrumentation Engine]: SYSCALL_INSPECTOR:Too long trace in the NTDLL!NtSetContextThread function.

Cannot install trial edition of VTune 2015

It extracts the files, then dies. If I keep the files around and run setup.exe manually it starts, then dies on "loading product.xml".

The bottom of the log file reads:

[t1410 2015.02.24 16.04.08 00000637] [wi_presenter]: INFO: Get clients for following component set: {3149A017-83E0-4629-AFDF-FACF72327B47}

Lack of Ivy Bridge support in current VTune

Slide 9 of https://software.intel.com/sites/default/files/Using_Intel_VTune_Amplifi...

shows a Sandy Bridge/Ivy Bridge Analysis category of pre-configured profiles.  However, with the XE2015 Update 2, there are categories for Sandy Bridge and Haswell, but none (besides General) which work for Ivy Bridge (see attached).   Which version of VTune, if any, is recommended for Ivy Bridge Memory Access analysis on

Problem with hardware counter analysis

I am trying to understand the behaviour of programs by running the hardware counter analysis. I tried running the program with multiple size datasets with a finite set of counters to be measured. But to a great surprise, vtune measures most of the counters and dumps in the log. But for few runs, it only measures very few counters among the same set. It also drops down the runtime of the application to a great extent. Is this behaviour normal or its some kind of a bug?

 

Collecting CPU Time for FLOPS calculation

Hi everyone,

I am trying to estimate the number of FLOP and FLOPS for my application by using hardware EBS running from the command line. I have implemented the  __itt_pause()  and __itt_resume() around my algorithm of interest. I run this command:

C:/Program Files (x86)/Intel/VTune Amplifier XE 2015/bin64/amplxe-cl.exe -collect-with runsa -knob event-config=FP_COMP_OPS_EXE.X87:sa=2000000 -start-paused --result-dir foo application.exe

How basic hotspot analysis is different from advance hotspot analyis

I run the application on intel vtune to extract the information about the functions that are consuming most of the time. Same application running with the basic hotspot analysis and advance hotspot analysis are indicating different functions. Can you please explain me what is the difference between these analyzers and what could be the reason for this behavior. 

Thanks you
