[QUOTE=Prime95;251664]I tried installing 32-bit Debian and soon descended into libcurl dependency hell.[/QUOTE]

I found my notes about how to get out of dependency hell. The 32-bit Linux version is now available!

The 32-bit version was built on Ubuntu 10.04, the 64-bit version was built on Ubuntu 10.10. If needed I can install 64-bit Ubuntu 10.04 and rebuild the 64-bit version. Just let me know if you run into glibc problems.

I'll repeat my minor feature request for the next version:
When doing P-1 work as [i]Pfactor=[/i], it reports like this:[code][Feb 8 13:37] Optimal P-1 factoring of M58020713 using up to 4608MB of memory.
[Feb 8 13:37] Assuming no factors below 2^69 and 2 primality tests saved if a factor is found.
[Feb 8 13:37] Optimal bounds are B1=685000, B2=18837500
[Feb 8 13:37] Chance of finding a factor is an estimated 6.38%[/code]Which is good. But if I specify the bounds with [i]Pminus1=[/i], it does not give the probability:[code][Feb 8 13:37] P-1 on M334000013 with B1=8250000, B2=250000000[/code]That's all it says. Can you please add the line that says "Chance of finding a factor is an estimated 7.39%"?

[SPOILER]Shouldn't the gwnum.a library contain the gwnum.o object ? I tried the official makefiles and it seems that its absence is causing ld to fail. OTOH, when I use the cmake build system, where gwnum.c is compiled in the process, everything links ok.[/SPOILER]
My bad - forgot about the makefile in the gwnum folder.

Maybe the libcurl static linking dependencies problems could be mitigated by having mprime sources being distributed along with libcurl ones as a single archive. There are many projects employing such scheme, so maybe mprime could follow such approach too. Bulding mprime would involve creating static libcurl along the way.

That would involve changing the P-1 worktodo line. I need to know how far the number has been factored to give an accurate probability.

[QUOTE=Prime95;251850]That would involve changing the P-1 worktodo line. I need to know how far the number has been factored to give an accurate probability.[/QUOTE]Any harm in adding that as an optional 8th parameter? (Pminus1=[id,]k,b,n,c,B1,B2[,tf])

[QUOTE=Christenson;251760]Hi Prime95...
Elsewhere, you suggested I try 26.4 for not getting six cores automagically recognized...I haven't been able to do that just yet...should I just jump to 26.5 and try that?

Meanwhile, six cores crunch away...real LL results in a month or so....patience, patience...[/QUOTE]

[QUOTE=Prime95;251763]Go straight to 26.5 unless you're using Linux 32-bit. I hope to get that built tomorrow.[/QUOTE]

On a six-core, 64 bit machine, I need help understanding why I might want to fool with 32 bit....except as a developer of 32-bit things.:batalov:
:busy: :cmd:

[QUOTE=Christenson;251929]On a six-core, 64 bit machine, I need help understanding why I might want to fool with 32 bit[/QUOTE]You don't. 32-bit is only for ancient beasts that can't run 64-bit.

Stupid question, but, why is 26.5 size 25 MB and 25.11 only 5 MB? :)

More optimizations. This question had been answered before somewhere else in this forum in more detail.
