The borged boxes are free labor. Like I said I don't dare do LL on them. I used to have some run DC's, but those have been replaced. I have had various borgs get wiped at times. One that I don't have access to anymore is turning in LMH-TF's all the time.

The newest one, I tried a couple of P-1's on (in the 100M digit range), on one core of four. Didn't care for it. That one I am using to do the 74->76 runs. The other machines, I had running various levels, until all of the earliest exponents were at 73. Now most all of the cores are running 73->74.
A lot of the earliest people in on the 100M digit range did not do enough TF on their exponents. I have been working in this range for years, before P95 was set to do exponents in that range.

BTW, I welcome anyone with a GPU to help out, especially taking exponents right up to 79 or 80.

 2013-03-30, 15:55 #3 Aramis Wyler     "Bill Staffen" Jan 2013 Pittsburgh, PA, USA 41110 Posts I'm just going to toss this out there because it popped into my head, but although it is a serious offer I don't actually expect you to take me up on it, Uncwilly. I run all my processing power in the LL range because I think that's where we are closest to falling behind - I could be wrong, but last I checked we were about 11 months ahead on DC and, mostly because of your coordination, we were well ahead in the LMH range too. But still, we always need more p-1 action in the LL range, so I'd be willing to trade up some ghz days if you like. Specifically, for every ghz day you can p-1 some candidates in the current ll range, I'll dedicate 10 ghzdays of gpu power to taking whatever number you want to whatever bitdepth you want. I do care about the LMH range same as every other range, I just try to go where I'm needed most and I know laurv works in the LMH range sometimes and can probably singlehandedly factor more of those to 78 in a day than get passed out.

I think that I will take you up on this offer.
Starting today, I will pick up some P-1's from GPUto72. I will start some of my slaves on these. To date, I have no P-1's in that range completed.
Once I have turned in a few, I will let you know here. Just take the next available exponent from GPUto72, in the 332M range, up to 79.

Please be sure to have enough RAM available to do a worthwhile P-1 job.

I will also take on one assignment to 79. One GHz year -- two days on my puny little 560.

(As an aside, this exercise demonstrated that I had made a really stupid mistake on the assignment form for 100M digit assignments. Thank for letting me know Bill.)

I have gotten 4 P-1 assignments from GPUto72, 2 will complete shortly, the other 2 are in queue right behind them. 2 cores total running P-1 (1 per machine). I will likely add 1 or 2 more cores tomorrow. I will also take more assignments.

Cool.

So you know, my exponent (332,309,699) turned out to have a 76.92 bit factor, so you only owe me 86.35 days of P-1'ing...
