Thank you for the information James Heinrich. I do appreciate your time spent locating it for me.

[QUOTE=James Heinrich;298842]If you have old results.txt, please submit them all to [url]http://mersenne-aries.sili.net[/url] if you haven't already. Any data I need will be automatically parsed from that.[/QUOTE]

Do you also need results from mfaktc and/or cudaLucas?

He doesn't [i]need[/i] them per se, but his site is capable of processing all results and tracks them; I upload everything. He has some nice features besides the collective P-1 tables.

I just noticed :smile:
I will upload more results as I get home. Too bad I don't backup mfaktc results files after submission.

[QUOTE=ET_;298897]Do you also need results from mfaktc and/or cudaLucas?[/QUOTE]I grab snippets of data from PrimeNet every hour, but unfortunately I can't get all the data that way (the reports are truncated), and not all the data I need is reported there either, so any and all results you want to submit (Prime95, mprime, mfaktc, mfakto, CudaLucas, factor5) is all very welcome.

James,

I fired up a small batch of the M83xxxxx exponents with poor P-1. They are moving quite fast and I'm going to help you out in properly testing these exponents. I copied all the tests from your web page (M8317429 - M8392961) and I'll put this into a spreadsheet and send you a copy so we don't cross paths. I have a full workload right now and I want to reduce my already assigned work so I'll start for serious in a few weeks or so.

Cheers,

PF

[QUOTE=PageFault;299083]I'll put this into a spreadsheet and send you a copy so we don't cross paths.[/QUOTE]No need, just let Prime95 register the assignments on PrimeNet and we won't cross paths (nor will anyone else who happens to want to work in that range).

You have a point ... I can register a load as assignments but then my worktodo will have 1460 lines ... updating will torment the server.

I just set the days to report to 7, so it only hits once a week

[QUOTE=bcp19;299095]I just set the days to report to 7, so it only hits once a week[/QUOTE]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.

PageFault 2012-05-11 00:57

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 % ...
