      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.
