VTune multithreading on multicore

Hi guys,

I am trying to run 8 different threads on 8 different cores. So my CPU time is greater than my elapsed time. One of the threads is taking a very long time when compared to the other 7. These 7 threads are taking up almost the same time with a very minute difference. I have attached a screenshot of this. Can someone please tell me why this one particular thread is taking this extra time? 

Thanks!

Could we assume you're not running on MIC, since I don't know of libgomp being available for MIC?

You should have enough context to choose a relevant forum (maybe the main VTune one, if you're not using any other Intel software tools).  We can't invent context.
