Halved in 34 days.

[QUOTE=NBtarheel_33;206427]Our only problem is if people start to lose patience with the assignments as they take longer and longer. For most seasoned GIMPSters, this won't be a problem, but it might be for the newer folks.[/QUOTE]

Well in my 7'ish years experience hardware advancements have pretty much kept up with larger exponent ranges.

I was probably (unknowingly) one of the early "fools" to try a 10M digit test in 2003 on, what was at the time fairly leading edge (P400). It took 15 months.

From what has been posted xorbe is the only one so far to admit doing a full 100M digit LL test and also expects to take about 15 months....probably on all 4 cores or a fairly high-end Quad.

I've got one thread running for 100M. With a Core 2 Quad architecture you have too much loss if you run only one thread.

I'm planing to upgrade to a 750er sooner or later. After that my 100M process can get the full attention ^^ ...

[quote=NBtarheel_33;197055]Countdown to proving M(20996011) is the 40th Mersenne Prime: 100 as of 0538 GMT on 2009-11-26. It took 50 days to clear 100 exponents, or 1.5 times as long as it took to go from 300->200. Looks definitely like exponential decay on the rate of completion, and I would say that we'll be lucky to see this last 100 cleared by April 1, 2010.[/quote]
100 - 50 took 73 days
50 - 25 took 34 days
25 - 12 took 21 days

I'm abandoning the "exponential" model

is nearly boiling dry (like the paint;)

So close it hurts!

I don't know how you got that info but I'm curious all the more now to know more about the specific progress on each. I guess you couldn't dig that up, could you, Primeinator?
