My point is that you won't be able to sieve much deeper by taking a
larger range and distributing it. Maybe you can sieve 1% or 2%
deeper, but that doesn't make it worth the effort. The reason is
that MultiSieve has to use trial division (at least for Cullen/Woodalls).
PSP sieving gets a huge advantage because it uses a discrete log.

I've been working on one in my spare time. I used a Mac version to
sieve the Cullen range in which I found the prime since I could sieve
much deeper than a P4 could.
In the meantime, head over to the pies_project and use your Mac to
find a new 100000 digit prime.
