[quote=10metreh;226393]OK, I'll try to coax some polys out of that.[/quote]
I've already gotten past the polys on the WinXp machine. It took about .5 hour. So unless you're interested "just for fun" you don't really need to run them, but thank you for the offer.

[quote=EdH;226394]Just a thought of perhaps, actually. Fedora 11 ran Aliqueit, Msieve, etc. rather well. F13 has annoyed me already with several changes that were not for "my" benefit. Now I have to study even more about another OS version to make my computer work properly.:down:[/quote]If F11 isn't broken, why did you fix it?

That is, you could consider downgrading to F11.

OK, just for narrowing down purposes, msieve stops after the correct amount of time (0.33 hours) on my i5 (running Win7). So it looks like a Fedora issue.

I would have nothing against running Ferdora or any other flavor of linux except that because lots of people on the forum use Ubuntu we share solutions to problems when they arise. These problems often have different solutions and/or syptoms on different operating systems. The same sharing solutions works with windows for the same reason.

There's more variety here than you might be thinking. I have four SSH terminals open on my desktop right now connected to different computers in the same department running CAOS, CentOS, Debian, and Ubuntu.

It is the primesearching circles on mersenneforum that are almost exclusively ubuntu or windows.

There may be less variety - depending on a place, on a strictness of company regulations. I, too, can open here 15 different terminals, and all of them will be SLES 10 and maybe some adventurous ...11s :razz:

[quote=Jeff Gilchrist;226182]With my latest RSALS job [[B]599_83_minus1 - SNFS(233)[/B]], I tried using LARGEBLOCKS and TARGET_DENSITY=80 to see how things changed.
In both target density cases, going from normal block size to large block size increased RAM usage a significant amount but decreased the ETA by 16% of the original time.

In both block size cases, increasing the target density from 70 to 80 increased RAM usage slightly but only decreased ETA by 2%.

Jeff,

Could you compile a new msieve windows binary 64-bit core2 version with LARGEBLOCKS and TARGET_DENSITY=80 and post it on your webpage? Thank you in advance.

In case someone else cares, I happen to have acquired another 2.8GHz machine that happens to have 1.5G of RAM. This particular machine won't run Fedora 13 - it refuses! Based on the mention of Ubuntu, I am trying that OS (10.04.1) and the machine appears to like it so far. Depending on my testing, perhaps I will be running an Ubuntu machine here. . .

Of course, one of the first tests will be Msieve with the same number as on the Fedora machine.

Any words of wisdom, or thoughts on additional math programs I should include, besides the obvious Aliqueit, Msieve, GGNFS, YAFU, PARI, GMP-ECM? I may have forgotten to mention some, but please feel free to duplicate something I'm already including but didn't list. I will probably still be running aliquot sequences, but I might at least check out some other areas.

Sorry this is bordering on off-topic. Please move it if need be.

Thanks. . .

That machine appears to be a no-go, although it did finish poly selection at the estimated time for a few tests. Unfortunately, aliqueit, ggnfs and other programs would arbitrarily shut down and occasionally the computer would shut off, all for no apparent reason. Maybe that's why Fedora 13 wouldn't even complete loading. . .

I noticed at work that the GUI of fedora 12 would freeze up at random on a 2GHz P4 I installed it on; FC11 and older had no trouble.
