This doesn't jibe with my experience - ever since I started visiting the top2.htm page a couple months ago (at which time I was only a few places away from you, as I recall), my results have been getting credit no later than a week after I submit them. The CPU-years credited appear to be appropriate to the size of the number that was tested, as well, although the "P90 CPU year" seems closer to what one expects of a PII, not a simple Pentium. The number of exponents I'm credited for is also remaining right in step with my posting of manual test results. >Early in February I was credited with 50 exponents tested, even though >I've finished 10 more since then, the figure on >http://www.mersenne.org/top2.htm hasn't changed and I've dropped 30 >places. Since you and I seem to be experiencing different things, it seems the update utility George uses may not be working properly. Aaron Blosser noted an anomoly w.r.to his account in a recent post. The only anomaly I can add to this list is that the identical account "MechEngrGATech" appears in two distinct places, currently 364 and 491. The spelling of the name is identical, so it doesn't appear to be due to a slight difference in spelling or capitalization. My main worry isn't so much the top producers pages as the possibility that some results aren't appearing there because they never were properly received or logged by the PrimeNet server (In which case George would never get them for his top producers updates, either.) I suggest you send a list of your most recent 10 results or so to Scott, and ask him to verify that they were received by PrimeNet. If yes, then the problem lies somewhere between PrimeNet and George's top producers pages. I do agree with you that for many manual testers, the top2.htm page is the only place they can see their work being credited, and it is important that such actually occurs. - -Ernst _________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers ------------------------------ Date: Sun, 20 Feb 2000 19:09:53 EST From: [EMAIL PROTECTED] Subject: Mersenne: problem with nonshared binary on MIPS (I sent the following to the list a few days ago, but it seems to have gotten lost in the shuffle, so here it is again.)

I believed the binary to be portable, since the MIPSpro f90 compiler manpages make no reference to a shared/non_shared flag and since no one has previously reported the problem you cite. But based on the error message you got it appears to be shared after all, i.e. needs the f90 RTL files. On a hunch, I tried adding a -non_shared flag to my compile sequence and it seems to be OK (i.e. the option is supported) but now I get the following error message: FATAL 9; I/O error (/usr/lib32/nonshared/crt1.o): no such file or directory. The only file I found in the /usr/lib32/nonshared (actually the /usr/lib32 /mips4/nonshared, due to a soft link from lib32 to lib32/mips4) directory is a 2.2MB file called libftn.a. I did find a crt1.o file in /usr/lib, but neither including it in the compile source/object file input list, not via -I/usr/lib/crt1.o worked - same error keeps repeating. Does any of the MIPS experts know if (as root, which I'm not on the system I use) one could move /usr/lib/crt1.o to /usr/lib32/crt1.o, since the f90 compiler appears to insist on looking for it there? In the meantime, I've posted a gzipped copy of the .so RTL files to my ftp archive: ftp://209/133/33.182/pub/mayer/bin/SGI/libf*.so.gz , and have added instructions on how one can install them in a local directory and access them there via the LD_LIBRARY_PATH environment variable. That should allow you to run the current shared executable. - -Ernst ftp://209.133.33.182/pub/mayer/README.html _________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers ------------------------------ Date: Mon, 21 Feb 2000 14:08:49 +1300 (NZDT) From: Bill Rea <[EMAIL PROTECTED]> Subject: Mersenne: Re: credit for manual tests > From [EMAIL PROTECTED] Mon Feb 21 13:10:30 2000 > > >Early in February I was credited with 50 exponents tested, even though > >I've finished 10 more since then, the figure on > >http://www.mersenne.org/top2.htm hasn't changed and I've dropped 30 > >places. > > Since you and I seem to be experiencing different things, it seems > the update utility George uses may not be working properly.

I had an email from George saying that I somehow got two accounts and the latest results sent in have been credited to the second account. He said he would fix that up. The other person who claimed they were getting no credit again has two accounts -- one under Ralph Green Jr. and the other under Ralph Green. I found him easily in the list, but he's since given up, though still on the mersenne mailing list. > My main worry isn't so much the top producers pages as the possibility > that some results aren't appearing there because they never were > properly received or logged by the PrimeNet server (In which case > George would never get them for his top producers updates, either.) > I suggest you send a list of your most recent 10 results or so to > Scott, and ask him to verify that they were received by PrimeNet. > If yes, then the problem lies somewhere between PrimeNet and George's > top producers pages.

Just exiting windows cleanly is fine. Or if you are paranoid, close prime95, and it will save its work in progress. You don't have to halt it first. The save is in the Pxxxxxx and Qxxxxxx files. >When I am ready to put additional computers into PRIME 95 service, >how do I have that work counted (added to) as part of my total >work-to-date (which I assume will effect my ranking and enhance >my family's esteem, pride, and renown)?

They could well be folks who dropped out some time ago and stopped working on new exponents. re the relative ranking within this group, I suspect the system is tracking a few more places than being printed on the listings. sticking around for the long run IS the best way of moving up. I run about 8 systems total ranging from 133MHz to 500Mhz and have managed to get myself up to around 47-50 by sheer persistence. I was running on nothing but a single P100 for almost a year before Primenet ever came into existance, I've retired that processor now as its time per exponent is just too high (besides its running linux now and I've never bothered to figure out the linux client). - -jrp _________________________________________________________________ Unsubscribe & list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers ------------------------------ Date: Wed, 23 Feb 2000 23:59:49 +0100 From: =?iso-8859-1?Q?Ignacio_Larrosa_Ca=F1estro?= <[EMAIL PROTECTED]> Subject: Mersenne: Pollard rho factorization algorithm This is a multi-part message in MIME format. - ------=_NextPart_000_003C_01BF7E5A.11B51620 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Where can I get information on the Pollard rho factorization algorithm?
