Does anyone have any more recent information on this exponent?

 2008-09-05, 15:08 #3 jinydu     Dec 2003 Hopefully Near M48 33368 Posts I'd like to LL test the exponent myself so I can break the record for the largest LL test ever carried out. How do I reserve this exponent with respect to Primenet? StarQwest was able to get his test of M100,000,007 recognized by Primenet. P.S. I've started already; 220,000 iterations done.

 2008-09-08, 15:10 #4 jinydu     Dec 2003 Hopefully Near M48 2×3×293 Posts The question in my previous post has been answered. With the intention of getting a residue every 1 million iterations, I set "iterations between results file outputs" to 1000000. Now that the 1 million iteration mark has come and gone, how do I find the residue? Thanks Last fiddled with by jinydu on 2008-09-08 at 15:11

What you set is the fact that Prime95 will write a line in your results files, not that it will save intermediate files. For that you need to digg into undoc.txt and find the lines :
Quote:
 You can have the program generate save files every n iterations. The files will have a .XXX extension where XXX equals the current iteration divided by n. In prime.ini enter: InterimFiles=n You can have the program output residues every n iterations. The default value is the InterimFiles value. In prime.ini enter: InterimResidues=n

According to this: http://v5www.mersenne.org/report_exp...&B1=Get+status

There is 17 LL test underway on 332M (100M digit) exponents. 15 by ANONYMOUS and 2 by simcon.

 2008-09-08, 16:54 #7 S485122     Sep 2006 Brussels, Belgium 2×3×7×37 Posts Indeed there are 332M tests underway. But I (and Jin Du obviously) expect to finish the 100 000 037 exponent well before the big ones. Jacob

So what is the largest exponent that is reserved? And can I be confident that the M100,000,007 record hasn't already been broken?

Indeed. All I got was a rather uninformative: "Iteration 1000000/100000039". Not even a 16 hexadecimal residue.

Anyway, I'm running the test on one core of a 2006 desktop with a Core 2 Duo E6700; the other core is being used for "normal-sized" LL tests.

I'm finishing about 1 million iterations every 4 days. At this rate, the test will finish in Oct. 2009. That may be a little optimistic though because I will not have direct access to the computer for most of the time. But I still think I have a good shot at finishing in 2009.

The way you phrased that sentence... You're planning to test M100,000,039 as well? I'll assume 100 000 037 was a typo; for the record that exponent has already been factored, as was mentioned in the MasterPrime 2006 thread.

1.04% done as of now.

You are right : I meant to say that I expected you to finish the test before the people going for 332M will finish theirs and that I though you expected the same. I tried to contract the two propositions and contracted them to much. As for the exponent it is not even a typo just bad memory and no interest in the actual nimber I could (and should) have written 100M instead.

If you have InterimResidues=1000000 in prime.txt you should get output like this:

M46019801 interim Wd1 residue A93B9072E8348331 at iteration 1000000
M46019801 interim Wd1 residue C04F8586F1A7D82C at iteration 1000001
M46019801 interim Wd1 residue 27E8898518996CB6 at iteration 1000002

 2008-09-08, 23:17 #11 Batalov     "Serge" Mar 2008 Phi(4,2^7658614+1)/2 3×13×233 Posts P.S. Just a thought. You've got to have those lines in the top section of the file... NOT after the tags in square brackets. And if you edit it but not stop/restart the program - the program couldn't care less. Also, on the same thought. Don't edit control files with the prime95 still running - it may overwrite some or any of your changes, when you stop it. The safest course of action: stop (or even exit) the Prime95. Add the line(s) to the prime.txt. Code: ... DaysOfWork=60 UnreserveDays=365 OutputIterations=10 ResultsFileIterations=1000000 InterimFiles=1000000 InterimResidues=1000000 DiskWriteTime=30 NetworkRetryTime=5 NetworkRetryTime2=10 DaysBetweenCheckins=1 ... Start Prime95. (Note a couple of other useful lines. And set OutputIterations=10 or even 1 if you want. Or a 100.) Last fiddled with by Batalov on 2008-09-08 at 23:29
