Are you profiling an application? If so, how long did it run under profiling? The image appears to suggest (in the log section) that profiling took much less than a second. Is that correct?
Hi Mr. Anderson,
I was running a small application to see if the light-weight hotspots is working. It is working now & thanks for the help.
When we ran the same command using the command line instead of GUI, it was giving us error. There were some issues with the Watchdog Timer & it was asking to "Disable NMI Watchdog when using PMU event-based sampling".
This article really helped.
this are the errors while doing the profiling of clusterw application.... i followed the steps from intel vtune amplifier doc but it wont work for viewing the source code ..... please help for the steps to profile any program and see the source code in vtune... i am using vtune in linux
this is error..
