Intel® Parallel Amplifier

Duration parameter of "collect"

Hello,

I am trying to gather some system-wide hardware counters for my application, X seconds after it has started, over a period of Y seconds. I am using the following command line:

amplxe-cl --collect my_custom_conf -target-duration-type=veryshort -duration 30 -no-auto-finalize -no-summary -data-limit=0 -resume-after=20000

and I expect the collection to start after 20s and last for 30s.

I have two questions:

vtune_amplifier_xe_2013 + how to compile

dear all,

I have vtune_amplifier_xe_2013, I used it one year ago to analyze the CPU time in my program. 

I remember that it produce the files: .dump and .xml

I do not remember anymore how to compile the program to get the previous files.

I do not remember the flags that I have to use in ifort.

Someone could help me, please?

I am not able to find the guide anymore. Now I am trying to look inside the  vtune_amplifier_xe_2013 folder.

Thanks

 

Intel VTune can not collect information & cause core dump

Hello,
we are using Intel VTune 2015 for profiling our application which is  running under operating system:2.6.32-504.1.3.el6.x86_64 Red Hat Enterprise Linux Server release 6.6 (Santiago)
CPU: Intel(R) Xeon(R) E5/E7 v2 processor
Frequency          2800004679
Logical CPU Count  4

I started four ngss.elf which is our product.

Events for measuring branch mispredictions?

I would like to measure the number of branch mispredictions (not specific to indirect/cond/ret etc). Do I understand the following two event counters correctly:

BACLEARS.ANY

​This will tell me exactly how many branch mispredictions occurred? (Probably the event counter I am really looking for)

 

BR_MISP_RETIRED.ALL_BRANCHES_PS

This will tell me how many instructions were executed/retired from a branch which was later determined to be mispredicted?

 

How to do Basic hotshot profile with intel 2015 + VS 2012 + MPI

Hi,

I just bought the Intel studio 2015 cluster edition windows. I need to do Basic hotshot profile with intel 2015 + VS 2012 + MPI for my cfd code. I am using a workstation with 2 cpu (2x12 cores). Using 1 cpu, I managed to the analysis successfully.

I can run my code in parallel using intel's wmpiexec.exe. I can also run my code thru VS 2012 by:

setting the launch command (Configuration Properties - Debugging - Command) to the full path for mpiexec.smpd.exe (eg C:\Program Files (x86)\MPICH2\bin\mpiexec.exe)

"Cannot start collection because the Intel VTune Amplifier XE 2013 failed to create a result directory" when running with MPI

Hi all,

I get this error:

Cannot start collection because the Intel VTune Amplifier XE 2013 failed to create a result directory. Unknown error.

when I run the following amplxe-cl command:

mpiexec -np 3 ~/local/vtune_amplifier_xe_2013_update7/vtune_amplifier_xe_2013/bin64/amplxe-cl -r mpi003 --collect hotspots -- ~/local/MyBuilds/HDGProject/release/install/bin/MyFESolverDP

VTune supported debug formats

Hi!

We have our own compiler that can produce debug information for executables. We generate HLL and CodeView debug formats now. Previous versions of VTune recognized at least CodeView format in our exectuables, but current VTune version does not recognize neither of formats. I was not able to find information about what debug formats are supported by VTune, only supported compilers. As one of the supported compilers is GCC actually, I can deduce that DWARF format is supported. We can try to support DWARF format, but can you confirm that CodeView and HLL are not longer supported?

amplxe: Warning: Cannot start collection of GPU events

Hi,

My system is Win 8.1 pro. I use VTune 2015 and I want to do some GPU analysis and get some GPU Metrics. I run "CPU/GPU Concurrency Analysis" in VTune Amplifier but cannot run.

When I use the VTune GUI and run the "CPU/GPU Concurrency Analysis", it appears this  in Collection log:

!Cannot start collection of GPU events

and there comes a window: amplxe-runss.exe

amplxe-runss.exe has stopped working

I even cannot shut down the command line window.
