Did I say anything about application support? No! Again, you are answering your own question.
I have found a few articles mentioning the smp granularity, but do not discuss the linux smp implementation within the context of granularity and overhead, and optimum degree of granularity.
Might be a language barrier on my part, but by your question, it wasn't apparent (at least not to me) if you're talking the locking granularity inside the Linux kernel (read: A theoretical question) or application performance running on Linux. As you talked about actual hardware (AMD Opteron CPU with 12 cores), I -assumed- that you were talking about application performance.
-However-, saying "Taking it lightly" doesn't excuse you from "being excellent to each other" rule. Your answer was rude and uncalled for.
