Mersenne: Re: Mersenne Digest V1 #474
the PrimeNet list Huh? What's that? Is there another PrimeNet list? If there is, please point me in the direction of how to sub scr-EYE-be. :-D Thanks. STL (That word is spelled oddly up there so this mail doesn't get bounced. :-)
Mersenne: RE: Mersenne Digest V1 #474
p.s. Does this discussion really belong on the PrimeNet list rather than the mersenne list? I agree. I'm guessing few Mersenne list participants have a decided interest in PrimeNet operations issues. Perhaps it suffices to post a gentle reminder of the PrimeNet list's address, as needed [EMAIL PROTECTED]. Well, when I had thousands of new machines hitting Primenet back in May, it did cause problems...fortunately Scott got on the ball and got it going, and it was also related to the 5.2M+ problem, but there were also times (Scott, correct me if wrong) that Primenet was already maxed on connections and had to refuse other incoming connections. Old news: Yup, PrimeNet saturated every 15 minutes or so. It has a 64 concurrent clients limit, which normally never gets above 5 or 6, and nominally hovered around 0.2 back then. I recall something crazy like 20 clients/sec. More old news: Aaron deployed an insufficiently tested first v16 NTPrime, which misidentified itself as a v15 FFT client. We got sloppy in the rush to get v16 done because the 5.26M exponents burned up *much* faster than anticipated. (v16 Prime95 was well tested.) Work had gone into the server's v16 assignments code, assuming the v15 client base was a stable stream. I ended up hacking the server to catch and fix the misidentified packets. (This is a good example of something for the primenet list.) Regards, scott
Mersenne: Double checked residues
I was looking through the list of double checked exponents and their residues (lucas_v.txt) and noticed four exponents near the bottom that only had one listed residue: 5510339,tompete,Tom,WT1,1070460990F198F8 5704913,jhertel,hstar-sc,WT5,26CF19E736BD10DA 5704957,jhertel,hstar-wb,WT5,BFB8E1CF9DC6DE9C 5757253,jhertel,hstar-sv,WT5,E63F0DA56CB5B8E9 Why is this?

A bug. They were reported by the same user using two different computer Ids. This was later detected and the duplicate removed. I just fixed the program that automatically moves items from the once tested to the double-checked list to not do this if the same userid reported both residues. Many thanks, George
