[QUOTE=Xyzzy;311440]We are downloading it right now.

We have the impression, from compiling msieve, that msieve can work with the gzipped .dat file. Is that correct?[/QUOTE]
Using zlib is set to on, by default.

However you will get a warning (and a precautionary exit) if you will have both .dat and a .dat.gz file in the working directory. msieve will tell you to move away (or delete) one of them.

I've just noticed that 8647_61_minus1, SNFS 240, 31-bit LPs, will have 185M raw relations when sieving is finished.
Isn't that a bit low ? 205-215M (the usual RSALS target for 31-bit LPs) might be more oversieving than necessary, but 195-200M probably wouldn't hurt.

The jury's out on whether the post-processing wall clock time saved by those extra relations would compensate the extra sieving wall clock time, though...

[QUOTE=ET_;311277][url]http://www.pcmech.com/forum/attachments/general-discussion/940d1028217709-prime-monster-stomp_monster.jpg[/url][/QUOTE]After using some rather nice micro-ATX boards I thought about building something which looked like that. A four-level stack, each stack containing a 2x2 square of cards, each card with a physically small SSD, would be a nice machine which would fit on a desktop easily enough. Never got around to building it though.

Greg, I think it's better to unreserve F1157.

I'll give it to Xyzzy.

:cat: <results.txt | grep prime

Are you trying to win a prize for excessive redirection? 'grep prime results.txt' does it with none, you are using three!

I might have excluded the "<", but I can't live without a :cat:...

Cool.
Now what's the LA ETA for S3m637?
