“No—mobs have no leader.”
They can have a leader but “mob” was not a good term.
My point is that remember, once upon a time, the battle for speed consisted of faster clock speeds and multiple instructions executed at the same time, to produce the fastest possible execution of a single instruction stream.
Now the speed race is a matter of running more and more instruction streams (cores) at the same time.
The former is like having great ideas. The latter is like increasing the headcount. The former is science. The latter is like administration.
To me a ‘computer’ is a core running a single instruction stream, and a ‘supercomputer’ is the committee of computers.
Especially as the systems grow, the mechanics of coordinating the activities between disparate cores can become as complicated or even more complicated than the mechanics of what has to happen inside the core.
