1 and 3 now.

Received two TF assignments above 79.3M on Saturday the 20th. These are the first "mainstream" assignments that I have received beyond the classical 79.3M GIMPS search space.

I can't get enthusastic about the effort to factor up to
the penultimate bit for exponents so far ahead of the LL wavefront.
The chance of finding a factor is small, and leaves well over
half the desired work (P-1 and the last bit) undone.

Meanwhile, the assignment of first time LL tests is
faltering. A few months ago, nearly all the available 50M
exponents had been assigned. The number available then
climbed to 7000 before dropping again.
Currently DCs are being assigned faster than first time tests.

Countdown to testing all exponents below M(32582657) once: 1

That last exponent is out in assignment for over 2 years

(LL testing to "alaendle" on 2008-11-15). Time to steal that back and finish off in somewhat 3-5 days?

I wouldn´t do that.
The exponent is being worked on and is nearly finished.
Moreover, no need to start another flame war about poaching...
Your CPU cycles will be much more well spent doing exponents that are not assigned.

How much is it "nearly" finished? several months to go? I'm just worried about such donators slowing GIMPS...

Do you have an advantage, if the test is finished earlier? Just wait for the exponent to finish. Where is absolutely no need for poaching. I can´t understand these stressing people...

I understand your willingness to see the milestones cleared (I feel just the same). But consider the following:

1. The current assignee has already donated a lot of time to process this exponent and he is still working on it. Therefore, it is unethical to take it away from him.
2. If you are concerned about GIMPS being slowed, testing an exponent that is already 92%+ tested is definitely not the right thing to do. It is a duplication of efforts, to absolutely no benefit. If you (or someone else) do it now, the original assignee will either notice that and possibly drop the exponent or even quit his GIMPS participation altogether in protest, or just finish the exponent and the result will be a useless triple check. That´s why I wrote your CPU cycles would be better used on not-yet-assigned exponents.

Ok, ok, I'm done. But i'll say one last thing: "Nice CPU there, alaendle. Stands the test of time!" ^_^
ATH, thanks for the assignments page, new to me...
