RichD completed GC_4_369 about a week ago, it is displayed on the lasieved page as still being post-processed:

Took me about an hour to get the post-processing started. The original files had the entire number (a C225) in them. MSIEVE would find 127 as a factor by 15 digit Trial Factoring. It would then search for a C223 in the .fb and .poly which still had the C225 in them. Eventually I realized this and checked the factordb and found out two P16 were also known, so only a C192 remainded:

That was a slog!

Edit: FactorDB seems to be down right now, but I'll add these factors when it returns.

I'll take GC_11_234 if it is still available.

GC_11_234 is currently in LA.

Factordb is down, so I could not report these factors.

I'll do L1364 - want to see how the new i7-4930 does on linalg

fivemack · 2013-11-27, 14:22

L1364.dat.gz, upon decompression, contains quite a lot (several tens of thousands) of corrupted lines such as

Code:

111,7D209C2D5D1B7E7,2B151D834BAC35,305,7DF56DA12864B276B7B9B177,,885185C9,41170,EB92F7016B118131193570D6:1F47E723E291,37416D49,08A2B10A38ADDF,4FD5,95EE4B,9FA11305,7EB:1F591119,7117967,3AD711A7A38D648AA18-,2C06869562A7118:5E22501,1F43D00FB11A91D6B93907ADDB0EB5116DC99F771305,7EB:17054CB6EAB6B109159,15F78242CA25C63,18951AD32

I'm sure the run will work despite this, but I'm a little curious as to how they got there.

This is not unprecedented, though usually there are fewer than tens of thousands of odd lines; it's led to me decompressing the files before use rather than trusting msieve-with-libz to handle weird corruption perfectly.
