Hello, everyone
recently, I am using Vtune to test my BSDE code in hotspot mode. I have found some insteresting things.
int a,a1,a2,a3;
float trans[4];
_mm_store_ps(trans,a_sse);
below are four lines of code
compile using gcc with -O0 Optimize optimization, the time each line costs increase as below
Hi,
I am currently evaluating vtune.
I develop a product in which the main application calls functions in dll "A" , A then calls functions in dll "B". I have no problem seeing the data for A however there is no profiler data for B.
Thanks,
Ben
Hi,
The VTune documentation http://software.intel.com/sites/products/documentation/doclib/stdxe/2013/amplifierxe/lin/ug_docs/hh_goto.htm#GUID-274DDE84-C483-45A7-B10F-85BD30943EEB.htm lists sampling-interval as one of the knobs that can be used with -collect locksandwaits. However, the following command line:
amplxe-cl -collect locksandwaits -knob sampling-interval=1 -- myapp
produces output:
I generated report in linux system for c++ code by attaching it to the running process using vtune amplifier and then when I am viewing it in windows
in top -down tree , it show that [outside any known module] has taken 30 % of CPU time while for rest 70% time it shows some function names.
I want to know what all are the possibile locations ,tasks,activities etc where this 30% time is getting consumed and is not mentioned in the report
Any kind of probable ideas may be helpful.
Thanks
According to this error reporting this is definitely a pre-C++-Exception-Handling application (which means pre-1996).
And I'm copying this error message by hand since copy&paste is also not yet invented!
Analysis is:
General Exploration - Knights Corner Platform.
On the console it says (again -- somebody deep in the library using printf since we don't know about C++-Exception-Handling):
I am unable to run "Cycles and uOps" analysis under Sandy Bridge / Ivy Bridge / Haswell Analysis. It says - This analysis type is only defined for the processors based on the intel microarchitecture code name Sandy Bridge / Ivy Bridge.
I am running vtune as administrator and "Run as Administrator". System details are
Product version: Update 5 (build 274450)
OS: Windows server 2008 R2 standard Service Pack 1
Processor : intel i5-3570 @ 3.4 GHz - Turbo boost disabled
Memory: 8GB
Can anyone help me on this?
Greetings, my apologies if this has been answered elsewhere - I have not been able to find a solution on this forum yet.
I'm unable to use amplxe-cl to collect memory access information. Here is a sample invocation with output:
I am using XE 2011. Seit last week I always get the Message while running Hotspot analysis""Failed to finalize the result. the result you ar opening is empty. this may be caused by an error during data collection. try to re-run the analysis"
I am using Wiindow 7, 64 bit, starting as admin. and when I press "Start Paused" it ieither gnore it and starts immediately starts or produce the above error message.

when I try to run bandwidth - Sandy Bridge / Ivy Bridge analysis, I get this error:
Error: PMU resources are not available. Hardware Event-based Sampling is not supported on this operating system.
Then I checked driver status - here's what I got. In admin commandline of coz.
I've been able to run vtune several times against our target application. But I haven't figured out how to get the symbols to go into the collected data. For example, when I shut down the program, I see the following warnings:
