I want to optimize my code which is written in c++ on linux platform.For that i am using Intel VTune Performance Analyzer Profiler .When i am identifying Hotspots , then it gives Error: "The Data Cannot be displayed,there is no viewpoint available for data ".
Current product is not "VTune profiler" (VTune(TM) Performance Analyzer is old product), that is, Intel(R) VTune(TM) Amplifier XE 2013, latest update is 5. Not sure if you use same product.
Note that old product has not be test in recent Linux* Operation Systems
Its Performance Analyser ...i.e i am using Intel(R) VTune(TM) Amplifier XE 2013 only ....i have downloaded trial version ,.,...it displaying the above mentioned error..........Sorry as it was checking performace so i had added word profiler in title.
What is OS you use? Ubuntu?
Assume that you use Hotspots collection - did you run target application in short time?
Yes i am using Ubuntu 11.04 ....basically i think target application's executable is not getting executed.For Executable which we have to dump in that i have made with the help of gcc -o "name of executable " "name of source" .this executable i am dumping in vtune and vtune is made to start then it gives the above mentioned error.
Please consider to verify:
1. In a console, run your application without VTune(TM) Amplifier XE - does it work smoothly?
2. In same console, run "/opt/intel/vtune_xe_2013/amplifier-var.sh"
3. Run "amplxe-cl -collect hotspots -- app" or "amplxe-gui" to verify it works.
Note: In Ubuntu 11.4, you may need to disable ptrace_scope.
cat /proc/sys/kernel/yama/ptrace_scope; "0" is expected, if it is "1",
Then do
$echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
