"The /parallel programming/ problem has been around for quite a while
and there are no signs it will be resolved any time soon. It was an
issue before clusters came on the scene and will be a huge issue for
I agree with you.
I have read sometimes that parallel architecture is the only way to go
faster than the Moore's Law, (let's recall us that this is a law coming
from the industry).
But it is not really the case, Parallel clusters follow the Moore's Law
: for the same price, you can have more and more of cpus in the same
That's what we see in the top500.
Then, today, the main problem that shows up is not the choice of the OS,
linux vs ms windows, (in fact Linux has not been designed for clusters,
so why not ms windows ?!).
The real problem for the one who doesn't use any embarassingly parallel
program, is clearly the parallel programming and scalability beyond
some tens of cpus.
