Re: Slow sqp execution in Ubuntu compared to Win7?

[Tottish]

Hmmm, I'm back at the computer but I can't really see where I have a choice
of which BLAS/LAPACK to use?
I use Synaptic and seem to have the libatlas3gf-base installed (ATLAS,
generic shared). Is this the one for me or should I install something else?
What?

I've made some tests and adjusted the stop criteria in sqp. When it's set to
default (eps) it only needs four iterations to hit the mark. This takes, as
I mentioned, about 0.24s where's one iteration takes 0.08, 2 iter takes 0.14
and 3 iter takes 0.19s. 
I guess this rather linear behavior points to the fact that it is the actual
calculation that takes time and not the linking, right?
On the Sempron running Win7 the difference was not noticeable when running
the same test. It took about 0.08 no matter how many iterations.

So what do you make of this? Am I stuck at the 0.24s or can I get it faster?

Have a good one, folks!
