I am running the svm application on intel vtune for hotspot analysis. The input file size is 2GB. The application run fine however the hotspot analysis on intel vtune GUI just provides the following summary information:
Collection and Platform Info
Application Command Line: /usr/local/hadoop/scr_svm
Operating System: 3.8.0-19-generic DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=13.04
DISTRIB_CODENAME=raring
DISTRIB_DESCRIPTION="Ubuntu 13.04"
Computer Name: HH-Xeon
Result Size: 933 MB
CPU
Name: Intel(R) Xeon(R) E5 processor
Logical CPU Count: 24
No bottom-up analysis is created that shows the modules and the functions for hotspot. In analysis type tab of intel vtune, I have used parameter "duration time estimate: over 3 hours".
Can you please explain, why I am not getting hotspot information?
Thanks
