And I'll get the sieve file for 6-10G to BOINC in the next couple weeks, getting that region to 500k and reducing the variety of n-depths by one more.

You also fail at a grasp of mersenne factoring.

Hint: testing k=1 in trial factoring, versus a prp test. No ,not the same computational length. No.

Edit: Wait, do you mean 2*p-1, or 2^p-1? ...

Yea, my silicon is a bit dated: 2x 10-core Ivy Bridge xeon @2.6ghz, 1x 12-core haswell xeon @2.5ghz.

I got 1440@15e7 done. I ran on 30 cores, which makes your curve count... staggering! Our combined effort so far is about 16% of a T60.

I've shifted to B1=42e7; 4e8 uses k=6 and less memory,...

Thanks for confirming, Ryan!

T70 is often represented by curves at B1=2.9e9 or so. If that level is complete, then T75 curves are what is useful now- that's B1=7e9 or bigger. That's one curve...

This is the slowest form of trial factoring available. You have exhibited zero knowledge of the structure of mersenne factors.

I did 800@6e7 and 650 @ 8e7. We're at about 1.5t50 combined.

T60 is about right for total effort here? I am moving to 15e7 curves presently. About 10,000 of those gets us T55 from here. I have...

Wait for what?

We haven't done nearly enough ECM to justify the time SNFS would take. You can wait for others to do the ECM, or you can contribute if you wish. I've done both, myself- I ran a...

i2224:C196 continues.
1300@2e7 complete, just over half a t45. Moving up to 6e7 and 8e7 curves; I'll get half a t50 done, and then jump to 15e7.

It's ECM; that number is always fuzzy. When a T-level has been completed, there is a 1/e chance of missing a factor of that size (if one exists).

So, when T65 is done, a 65-digit factor is missed...

It really doesn't matter how long it takes any program to get to 68 or 69 bits, when ECM has ruled out factors below ~67-68 DIGITS.

LaurV is just trolling.
