[QUOTE=James Heinrich;299097]If you're only doing these kinds of assignments, you could set to update only once a month; all the work should be done and reported complete before any updates are needed.[/QUOTE]
With the program running, I could not select above 7, which is ok since I only have 1 core on the 8M and the rest LL.

[QUOTE=PageFault;299101]Sounds like a plan to me - I'll set the update to 30 days. I can knock off the whole batch in 50 days, about the time it takes for a first time test on the second core.

I am doing stage 2 in 30 minutes, 480 of 480 relative primes in one pass using 1735 MB of 1920 MB ram allocated. The BS extension is being used, results.txt shows E=6. The bounds are B1=95000 and B2=1662500 with the probability of finding a factor estimated at 3.9 %.

I hope I get lucky ... my entire history of P-1 success rate is 3.78 % ... I did better at TF, 4.9 % ...[/QUOTE]
Don't forget, those were P-1'd already, just poorly, so you may not find as many.

If you modify the text file yourself, you can choose almost anything you want, down to and including 0.04; for the first 6 months or so of my GIMPSing, my computer reported slightly more than once per hour :smile: (Of course, you'd be looking at 30 days, not once an hour :razz:)

Well, the easy factors have already been found and these tests didn't have the easy ones. We shall see the stat for the batch in about two months. The bounds are deeper than the original runs, significantly so.

Crap ... when I started this project I was doing similar ranges ... in the ancient ages ... I had a Pentium II, can't recall the total ram in the box but IIRC I allocated a massive 64 MB to prime95 ... too bad the results.txt files are long lost ...

In the ancient ages, we used to ask George for blocks of work and then set checkin at 59 days, making sure to do a manual communicate around 55 days. It was all good ...

Heh, I've only been at it a few weeks longer than my join date :razz: (then again, I was three when the project started :razz:)

Man... Kids these days... They just don't appreciate what is was like...

Walking five miles to the punched card reader...

Through blowing snow. Forty below...

Uphill in both directions.... :razz:

And we are all glad you're doing it. You'll be seasoned after a decade or so ... I first heard about GIMPS in my first year of engineering school. There was a faculty wide mandatory computer course, writing crude code in Fortan77. One of the assignments was a program to determine primality ... I think mine crapped out at tests around the number 64000 ...

My mom can tell me all about punched card readers... but the snow's all your fault for living in Canada :razz: (I do get my fair share of it in Illinois, though the -40 admittedly is something I haven't experienced.)

Heh, any quick 5 liner in any (reasonable) language you want can easily hit 10 digit+ numbers these days :razz:

I hear you ... in some parts of the world things are still hard though ... I recently returned from Africa. I spent 7 years there, until a coup d'etat chased me away. In the bush, the best means of data transfer was to strap the punch cards to the belly of a pet sheep ...

Seriously, I was travelling 100 km to the nearest internet cafe, with a connection equivalent to a 1990's dialup connection. It sucked ...

Anyone remember the early modems, where you put the telephone onto the little mike / speakers thing ... it looked like headphones ...

Yes; in about 1978 I had a portable terminal from work to take home (was it a TI - Texas Instruments?) You put the phone handset in the rubber cups. It was a 300 baud modem and used a roll of thermal paper. It was like a little typewriter in a portable case.

When I was at the University of Illinois in 1976 we all thought that the self-service card reader was the greatest thing going. It sat on the counter and was convenient for inputting small student jobs. Learning PL/C as part of my MS in Library Science.

The University of Illinois is still one of the greatest research libraries in the world. It is the 3rd largest academic library system in the United States. Harvard, Yale, U of I.
