gmpbench -- how to utilize all CPU cores?

[Steffen Brinkmann]

Hello Torbjorn,

I guess I have to clarify my statements above... Before all: I didn't 
mean to complain or being rude. I am aware of the amount of work and 
well-written code that you give away for free because you want to. And I 
appreciate that.

My point here was (and I admit that this was not clear from my 
statement) that a library /intending to be parallel/ must be shown to 
scale well in order to be used by serious users. If a library is 
intentionally left serial (or to the largest extend so), it can still be 
a "serious" piece of code. And GMP cerainly is.

In a private discussion, Tor gave me some insight on why GMP should 
remain serial. I see that this is a well-informed decision and respect 
that.

That said, I think it would be nice to have a parallel library /on top 
of GMP/ for scientific purposes. But that is a different project and not 
to be discussed here.

Again, my apologies, if my comments came across rude.

Cheers, Steffen
