Hi,everyone,when I was using VTune Amplifier XE 2016 update 1,I had these problems:
When I run the command line:
amplxe-cl -collect hotspots -verbose --target-process myProgram & I receive the following error:
amplxe: Collection started. To stop the collection, either press CTRL-C or enter from another console window: amplxe-cl -r /opt/intel/vtune_amplifier_xe_2016.1.0.424694/bin32/r000hs -command stop.
amplxe: Error: [Instrumentation Engine]: Pin is out of memoryPin is out of memory
amplxe: Collection detached.
amplxe: Collection failed.
amplxe: Internal Error
I am trying to analyse an offload using VTune. I have put the following command in the script file along with mpirun -
amplxe-cl -target-system=mic-host-launch -collect advanced-hotspots -r xeonPhiAnalysis
I also added the following line in bashrc and sourced bashrc -
I am submitting the job through PBS with 1 MPI processor. (When I log on to the node and do "top", it doesn't show the code running) The run goes on till 1 minute by PBS and then i am getting the following error -
vtune version : VTune Amplifier 2016 for Systems
command is : amplxe-cl --collect hotspots --target-system=android:Coolpad8750-0xc2fda1f -r d:\profile.data --target-process=com.x.androidhttpserver
the target app is lanched success , and is waiting for debug , bug vtune failed to collect data from remote android device.
I've used vtune_amplifier_xe_2016_setup.exe on Windows 7, but today when I tried the same on Windows 8.1, right after extraction, the installer seemed to abort. Not sure if some setting or feature is missing on Windows 8.1. Log file found in AppData\local\temp folder is included below. Any help/BKMs are appreciated. Thanks!
I've been using Vtune to profile my OpenMP application, and it tells me that a lot of the CPU time is spent in Overhead time, under the "others" category. Could you let me know what this category entails, and how I can further root cause this?
I have offloaded a function in CAM model of CESM to the Intel Xeon Phi and trying to optimize it further. How can I use Intel Vtune AXE to profile CESM which has an offloaded function on Xeon phi?
[currently posting here since the Intel Premier Support portal does not seem to work for me - I stop at the first step, where I am unable to select my product. Forced to use Internet Explorer 9]
I am currently evaluating VTUNE Amplifier XE on a peculiar Linux setup (Gentoo-based) with a Linux 3.10.17 kernel patched with the Xenomai RT framework, release 2.6.4. I am currently looking for a Linux equivalent to the 'SystemViewer' profiler available on VxWorks systems.
One of my colleagues is wondering whether the internal format of the databases used by VTune to hold performance data is documented anywhere.
The PerfExpert tool generally uses HPCToolkit to collect performance data, but in many cases the users already have some VTune data, so if the format is documented we could expand the analysis to include data from multiple sources.
(We are also looking forward to future systems for which we expect VTune to be available earlier than HPCToolkit....)
