Done. Will do 599_73 while C147 is still not ready. (trial filtering was run. Will wait for 1.7Gb to repeat.)

Batalov 2012-04-09 01:11

I get a feeling that there will be enough time to clear out one more - 1973,61-.

Nice split = p92 * p102.
Posted to factordb.

Heading out of town for nearly a week. Afraid to take another in fear it may not be done before I depart. Still plenty of variety for others at:

1973,61- is not ready
 
It is undersieved (27-bit is bad for this size! [B]4M[/B] out of 15M relations were redundant and 11M are not producing a matrix.) Sieve some more, in a separate folder, and I'll be happy to pick up extra relations (3-4M more, because half of them will be redundant.)

I'll do 1627_67_minus1 instead.

[/QUOTE]
The analysis of relations' specialqs shows that if you sieve above 32M (where this project stopped) you are going to expect on average only 1M new non-redundant relations per every 4M range. So I recommend sieving at least in the 32-38(better 40)M range.

557,73- is done.
599,73- is done.
1627,67- in the morgen...ning. (ETA 8am)
...and C147 will be really ready then. :-) Morgen, morgen, nur nicht heute.

I'll take 1567_67_minus1.

EDIT: Also taking 541_79_minus1.

I have updated the reservations, terminations, and expanded the range for 84969569171_19_minus1. Thanks :smile:

Batalov 2012-04-09 18:20

1627_67_minus1 is done (that should help a bit with the disk space), and C147 seems ready - I am finishing it now.
I'll finish 1973_61_minus1 when it's done upping.

Batalov 2012-04-10 00:21

I would suggest adding a [URL="http://ggnfs.svn.sourceforge.net/viewvc/ggnfs/trunk/contrib/remdups/"]remdups[/URL] server side run in the rsals_data/ folders (triggered by 'all jobs received'; and/or once manually on the gradfathered projects).

Something like (where $i is the root name of the subproject)
[CODE]gzip -dcfq $i.dat.gz |remdups4 222 |gzip > $i.rmdup.dat.gz[/CODE]
(you can redirect stderr into a report file, too)
This will save quite a bit on file transfer times.
It will also help to recognize the undersieved projects better.
