[QUOTE=RichD;296949]I'll take 619_79_minus1 next[/QUOTE]

... which splits as:

[CODE]prp73 = 7924217965438112098053969805516327856887201339188333254236564057590093971

It looked like 2341_61_minus1 might have enough relations to build a matrix, so I tried it.
Sure enough, so the factors are:

[CODE]prp88 = 4016563746302175398406200511185529316824771552617063663329449805290863636683630299185687
prp115 = 3634257656839736405801955886533204785428377931039875700957617506963223918635405349752238700264217654929700270531603[/CODE]

(Thanks to Carlos for pointing this out.)

607_83_minus1 is done, 797_79_minus1 in progress.

Lionel,

What about creating a mersenneforum.org team at RSALS where, while we wait for numbers to post-process, we help on sieving?

Carlos

Please reserve 3281533_37_minus1 for me.

pinhodecarlos 2012-04-26 17:16

[QUOTE=pinhodecarlos;297246]Please reserve 3281533_37_minus1 for me.[/QUOTE]

Please unreserve it because although enough relations were achieved to build the matrix my machine just went so slow. msieve was eating almost 7.5 GB of memory out of 8GB.

In fact, I had not reserved 3281533_37_minus1 for you. Yesterday evening, I meant to post "Are you sure ? One of Pace Nielsen's 8-core computers might be a better fit for this task, because it's likely to be a pain :smile:", but the anti-flood limit of 120s between posts caught me, I switched to another tab, then forgot about this one :grin:

Well, why not ? :smile:
But it's not up to RSALS (squalyl & me) to decide, because post-processers can already do it without interference from myself, and they're free to run whatever they want when they're not post-processing :wink:

pinhodecarlos 2012-04-26 21:07

Please reserve 2153_61_minus1 for me. Thank you.

pinhodecarlos 2012-04-29 07:58

Taking 653_79_minus1.

pinhodecarlos 2012-05-01 03:04

Taking 1291_73_minus1.

pinhodecarlos 2012-05-04 17:08

Lionel,

You moved 2063_71_minus1 to post-processing queue but you set SALPMAX and SRLPMAX as 2147483648, a 31-bit prime. Do you think 129 M relations are enough for this case?

Carlos
