I first look at the expected passes, expected fails, etc. If those numbers match up, then I do what I said above . Otherwise I look at things that have failed that shouldn't and/or passed that shouldn't have (this, should almost never happen because all the Cilk plus related code are all enclosed between inside an if (flag_enable_cilkplus) statement).
