I'm using intel amplifer xe 2011 to analyse my program's performance on multicore system.
I set for example 4 workers to run my program. Note that i'm using the cilk plus langage.
The hotspot show me that 4 threads are activated but there is one thread that doesn't work (there is no cpu time).
I have attached a picture that show an example.
have you an idea for this problem ?
Thank you in advance.
