On http://www.mersenne.org/status.htm I find:

July 19, 2002: All exponents below 10,000,000 tested at least once.

whereas in http://www.mersenne.org/primenet/summary.txt I read:

8300000 8399999 43 6 8 1332 810
8400000 8499999 28 2 19 110 1977 229

9800000 9899999 7 329 3
9900000 9999999 3 414 3
[/code:1]
which I interpret that there are still some LL tests (and trial factorings) in progress.

What is true?

The first figure is the correct one as it comes from George's databases. The Primenet server can be quirky at times and people also return results to George directly which do not show up on the Primenet server. So go with the first figure.

More than that, I was able, purely by accident, to make very old exponents (actual mersenne primes too) resurface on the primenet servers just by crunching them and, again accidentally, sending in the results.

George's database is the only one to trust... that is if/until the new server is made. :)

Most of the exponents below 10,000,000 that the server lists as first time tests were tested once but had errors reported during the run. I intentionally have the server re-issue these as first time tests as the first test was likely no good.

Order of assignments
 
It seems that a client always gets the smallest exponent of the requested type. Every day at 6:00 UTC expired exponents get added to the list, these get then assigned during the next few hours. But some exponents are always listed as available and seem never to be assigned, e.g. in the range of doublechecks the entries 26, 7, 2 for the ranges 8000000-8299999. What exponents are they and what is happening with them?

[code:1]
7900000 7999999 10 354 1029

8000000 8099999 20 3 26 454 1341
8100000 8199999 52 7 705 1647
8200000 8299999 37 60 97 331 2 474 874
8300000 8399999 46 3 9 802 1337
8400000 8499999 47 1 20 1317 980

A similar case in the range 15200000-15299999 for first-time LLs: thereĀ“s a "1" hanging about for the last couple of weeks or so.


All times are UTC. The time now is 19:10.
