[Beowulf] Stroustrup regarding multicore

Jim,

I would go even further. It is definately true that from physics some  
scientists learn programming really well, at the best level i'd say.
That's not their job however. From hardware engineering sometimes  
even better low level programmers get on the scene.

The point being that a great low level programmers can do many low  
level jobs, whereas 99% from the PHD's have no clue where to
even start. Those great low level coders are without exception by  
definition of what IQ is, high IQ persons (let's just consider
technical IQ here), not seldom 180+.

Some definitions of what a high technical IQ is as it was not so long  
ago written on the wiki pages,
is managing to distinguish tiny details and from those details  
managing to understand everything from fundamental
conceptual level (this is my own words, the social dudes have a few  
thousand more pages on this most likely).

So from that great low level coder you know he has all that.

180+ is more than what most PHD's have. Additionally most are busy at  
conceptual level more than
implementing tiny details into code at cycle level.

Therefore it is easy to deduce from the above lemma's that it is more  
likely that the coder can understand
the theories the scientist wants to implement, than that the  
scientist will be able to within 10 years implement
the code real low level, provided he has the TIME to learn  
programming that well.
