Very nice.

49.5 hours on i7/2600 -t3 for 7.1M matrix

Less than 12 hours to the start of the challenge. I think it will be wise not to start any download of a post-processing integer if it will take more than 15 hours to download.
By the number of wu's in progress the server will be busy for the first few hours of the challenge.

Sorry for this inconvenience but it is better for the project. I am too much involved on this challenge inviting a bunch of teams in SETI.USA name that I don't want the server to fail.

It looks as if I've got quite a lot lined up for me, thanks to the June Showers lot sieving 15e fairly vigorously.

I'll post-process L1902 and all three of the aliquot-sequence numbers in 15e.

It may take some time: whilst I have as fast a machine as Intel will sell for reasonable money, I have only one of it - most of my resources are on sieving F1373.

I'll take the two XYYXF numbers on 15e, once sieving is complete.

Taking GW_2_757

I have an i5 Haswell with 16GB of memory. If you'd prefer to not do all of these 15e numbers yourself, and 16GB is enough, I could take one or more of these. :smile:

Mini-Geek: if you are willing to throw in some cycles, would you mind taking L1902?

It should take about 8GB memory for probably about a week.

I'll post-process two 14e numbers.

Ok, I'll take L1902. I'll start it after GW_2_757 (ETA 18h for the LA).

which has 40875*x^6+y^6 smooth and 40875*x^6-y^6 not.

So the NFS@home contributors have factored the same number twice, once under the wrong name. :pancakebunny:

C758 done with three-way split. Unfortunately, for the second time.

[B]But the factors have already been in factordb for two months[/B]; they were added 2 April 2014 at 1830 and 14 April 2014 at 1126.

The P62 is factor 16282 in Paul's file [url]http://www.leyland.vispa.com/numth/factorization/cullen_woodall/2014q1.txt[/url] and is quite an impressive ECM hit - the ECM data is in factordb.

I have checked that none of the current-queued 14e numbers are currently factored in factordb.
