Hi, I am using vtune amplifier XE 2013 to profile my program. The runtime reported by my program is 214047.34 seconds.
The time reported by Amplifier is as follows:
Elapsed Time: 85076.861
CPU Time: 84286.360
CPU Usage: 1.000
Executing actions 100 % done
I checked files created at the beginning and end of the program run. The creation time is about 2.5 days apart, which is close to 214047.34s runtime reported by my program. Vtune reported time is about 1 day.
I don't have any multi-threading in my program. I was doing hotspot analysis: -collect hotspots. OS is linux Sles10. Why does vtune report a wrong elapsed time?
