Largest LL tests ever completed
 

Here is a list of the, [B]at its time[/B], largest LL test completed ever and when they were record holders:

M79299959 until 2006-12-18 by Eric Hahn
M100000007 2006-12-18 -- 2009-09-06 by William Christian (StarQwest)
M101100011 2009-09-06 -- 2010-02-08 by rudimeier (Serge Batalov)
M150000091 2010-02-08 -- 2010-07-12 by jinydu
M332197123 2010-07-12 -- until now by xorbe [Suspect LL with error code]

It would be nice to know if someone has information about older record holders.

M340705633 due 2012-04-19
 

It is probable that the next record holder will be M340705633 expected to finish on 2012-04-19 by Smok_bmv presently at 93.70%.

M127 1876 François Édouard Anatole Lucas

Strictly speaking, that wasn't an LL test...

I [TEX]\neq[/TEX] rudimeier ...but if you really want, then you can [URL="http://www.mersenneforum.org/showthread.php?p=187645#post187645"]keep[/URL] me in that table.

I had that number saved from a dead computer (which had ECC) and then restarted iterations from 45% done half year later on another (without ECC [I]and[/I] with 4 threads); and not surprisingly I paid for that silly rush with an incorrect residue. Good luck to Smok_bmv (especially if he uses ECC, otherwise he may be just heating up the planet)!

Revised list
 

OK I am trying to get it right now:

M79299959 until 2006-12-18 by Eric Hahn
M100000007 2006-12-18 -- 2009-08-27 by William Christian (StarQwest)
M101001001 2009-08-27 -- 2009-09-06 by Serge Batalov [Bad LL, result uploaded to the server 2009-09-09]
M101100011 2009-09-06 -- 2010-02-08 by rudimeier
M150000091 2010-02-08 -- 2010-07-12 by jinydu
M332197123 2010-07-12 -- until now by xorbe [Suspect LL with error code]

Well I'll be gratefull for any corrections and additions.

Concerning the LL test for M79299959 it should have been completed sometime between [URL="http://75.102.3.20/civis/viewtopic.php?p=15466714&sid=9e03e752b40d24cb54d20251beaa8e48#p15466714"]2002-01-14[/URL] and [URL="http://www.mersenneforum.org/showpost.php?p=87620&postcount=194"]early January 2006[/URL]. Prime95 could not handle exponents that large until version 19.0 (mid 1999).

M100000039
 

... and we have to mention jinydu who fought braveously with M100000039 which was completed on 2009-09-09 but was beaten on the finishing line both by Serge Batalov (M101001001 2009-08-27) and rudimeier (M101100011 2009-09-06).

It seems his computer overestimated running time. It might even be complete in a week :smile:

*Hours* to go!

[URL="http://www.mersenne.org/assignments"]www.mersenne.org/assignments[/URL] is rounding off the status to 100.00% complete. Should be done in a matter of hours!!!

...What effect might it have on GIMPS if this number were prime, and hence took the next EFF prize far earlier than expected?

[QUOTE=NBtarheel_33;292706]... took the next EFF prize far earlier than expected?[/QUOTE]Why? What is the expectation time frame? And if it turns out prime then congrats to the lucky person involved, but it doesn't really affect me in any way, I didn't run the number.

Besides the prize is not really worth the effort if all someone is interested in is the money. They would have a better expected return if they buy lottery tickets instead.

Edit: If the machine doesn't have ECC memory then I fully expect to see errors in the result.

As expected...
