Problem loading of Advanced hotspot results into GUI with 2015.4.0.410668


Loading of Advanced hotspot results into GUI leads to an infinite loop of some sort and eventually pops up the dialog saying VTune is not responding. Most of the results seem to come up on the Summary page but the progress bar for "Collection and Platform Info" gets stuck at about 80%. amplxe-gui burns 100% CPU, apparently waiting for some mutex to be released, see strace below.

All other analysis types work ok. Displaying the results from the cli client works ok, e.g.:

Uso di Intel® HAXM per lo sviluppo di app Android* Wear e TV

Android* ne ha percorsa di strada prima con i telefoni, poi con i tablet, Google TV*, Android Wear*, Android TV* (in sostituzione di Google TV), e Android Auto*. Per gli sviluppatori può diventare impegnativo realizzare e testare le proprie app su tutti questi tipi di dispositivi. Aggiungete a questi dispositivi fattori di forma e risoluzioni diverse e diventerà ben presto un problema complesso di verifica e test dell'app. Abbiamo Intel® HAXM che ci viene in aiuto.

amplxe: Error: [Instrumentation Engine]: failed to create the detach process (clone failed)

running command

amplxe-cl -target-process dsd -collect hotspots
amplxe: Collection started. To stop the collection, either press CTRL-C or enter from another console window: amplxe-cl -r /r000hs -command stop.

then stopped but got the following error:

^Camplxe: Error: [Instrumentation Engine]: failed to create the detach process (clone failed)
amplxe: Collection detached.
amplxe: Collection failed.
amplxe: Internal Error

Could anyone help? Thanks

Program is faster when launched from VTune


I've noticed that if I time my program launched from the command line, it is slower than when I launch it from VTune (~25sec vs ~18sec). I've already checked that I'm running the same binary with the same options. Also, when I run it from the command line I run it 5 times consecutively.

I've noticed that, when launched from command line, the CPU stays in "slow" mode (at 1600MHz measured by CPUz), but when launched from VTune the CPU enters "turbo mode" (goes up to 2400MHz measured by CPUz).

Advanced Hotspot analysis problem

I’m trying to analyse an OpenCL program with VTune Amplifier XE 2015 (update 4) using VS2010 and VS2013 on Windows 7 enterprise.

Under "Algorithm Analysis", I choose 'Advanced Hotspots", and then select, from the "Analyze Processor Graphics hardware events" dropdown, either "Overview" or "Compute Basic", I get the banner message:

 “Processor Graphics analysis is only available on systems with Intel HD graphics and Intel Graphics Driver installed.
