Use Intel(R) Performance Tuning Utility (iPTU) to view sampling result from VTune(TM) Performance Analyzer

 

Why do we need to view VTune(TM) Performance Analyzer result in iPTU?

Intel® Performance Tuning Utility (iPTU) is small utility but useful, the user doesn't need to run installation program, simply unpack the package in the disk. Absolutely the user should run "build-driver", "insmod-vtune" and "install-boot-script --install" to install sampling driver if the user hasn't installed VTune(TM) Analyzer first in same machine (iPTU and VTune(TM) Analyzer can share vtune driver in one machine). 

Consider this situation, if other people provided sampling results to you, but you only have iPTU installed. Actually you don't need to install VTune(TM) Performance Analyzer, just view sampling result in iPTU directly.


How to view sampling result in iPTU?

1. Downlaod iPTU from http://software.intel.com/en-us/articles/intel-performance-tuning-utility/, and extract it in your hard disk.

2. Run iPTU - put??_int_lin_intel64/eclipse/eclipse, for example

3. Use menu File/Import -> Import Intel(R) Experiment

4. Browse into the directory of result, like as "$user/workspace/Project1/.vtproject.data/Sampling/ar50" (for example) in "Experiment directory to import" and click "Finish".

5. You will see hot functions for your interest of module

Note:

1) If your interest of module is not under ar50 directory, please copy it to "ar50/all", then right-click on "Import Project/ar50" of "Tuning Navigator" window -> do "Re-convert"

2) iPTU doesn't support to open .tb5 file directly, just experiment directory
