The goal of this new application is to find all the imprimitive fields unramified outside of a given set of primes. We start with the set {2,5}.

During testing I noticed that this app had more consistent run times, around 20 hours per WU on my 2.6 GHz core i7. You will also notice quick jumps in the progress meter followed by slow periods. This is normal behavior.

I wonder if app use SSE (1,2,3,3s,4.1,4.2) or other "special" instructions?

Time is with HT enabled?

No, I dont believe SSE is being used. We use the gmp library (via pari), which is supposed to be really efficient, but I dont think they are using SSE. And the app does not utilize hyper threading either.
