msieve has stopped breathing in the middle of execution.

ray10may · 2017-04-10, 17:42

I'm working on Windows 8.1 Professional with core i7.
For the given n in the website
n=2881039827457895971881627053137530734638790825166127496066674320241571446494762386620442953820735453

it stopped working in the middle giving error as shown in the images. It was working well for the polynomial selection, and for the initial steps of the sieving phase, didn't give any error. But suddenly in the middle this error came out. Please Help

.

You can try restarting msieve manually, by copying the last command from the text window with -nc2 changed to -ncr -nc3.

You can try starting factmsieve.py the exact-same way you originally did, which will restart the linear algebra step (the one marked -nc2). The factorization may finish normally. For a bigger project, the first option saves time, but in your case this is a small-enough project that restarting the LA step won't cost you much time.

If neither of those work, post the log file, which may contain the specific error msieve is coming across.

Could you please explain this 'manually', I'm new to this(GGNFS) I don't know how&where to perform these modifications (-nc2 --> -ncr -nc3.)

when I start the procedure in the same way as previous it gives me error(shown in the image)

prompt goes in read in read only mode..after giving error at -> msieve -s example\example.dat -l example\example.log -i example\example.ini -
nf example\example.fb -t 4 -nc2

so I'm not able to write this after error
-> msieve -s example\example.dat -l example\example.log -i example\example.ini -
nf example\example.fb -t 4 -ncr -nc3

(If it is what your 'manually' means).

example\example.log (the parameter after -l in the command you quoted).

This is the screenshot of my example folder, and it does not contain 'example.log' file.

Check the one between example.lcf and example.log.T0. Many extensions are hidden by Windows by default.

Yeah...now example.log.T0 has been changed to example.log.
I'm attaching it. please find.

I'm attaching it. please find.

Huh? In your screenshot, there was a file "example" before example.log.T0. That file is likely called example.log, but windows believes users might get confused if they saw .log, so they just show the file name without the extension.

The log you posted doesn't help us; it only shows the polynomial. If you renamed example.log.T0 into example.log, you didn't post what might help us figure it out.

This is the content of that example file(The one with setting icon in the screenshot)

which is nothing but n.

ray10may Mar 2017 2²·3 Posts	msieve has stopped breathing in the middle of execution. I'm working on Windows 8.1 Professional with core i7. For the given n in the website n=2881039827457895971881627053137530734638790825166127496066674320241571446494762386620442953820735453 it stopped working in the middle giving error as shown in the images. It was working well for the polynomial selection, and for the initial steps of the sieving phase, didn't give any error. But suddenly in the middle this error came out. Please Help.

VBCurtis "Curtis" Feb 2005 Riverside, CA 4861₁₀ Posts	You can try restarting msieve manually, by copying the last command from the text window with -nc2 changed to -ncr -nc3. You can try starting factmsieve.py the exact-same way you originally did, which will restart the linear algebra step (the one marked -nc2). The factorization may finish normally. For a bigger project, the first option saves time, but in your case this is a small-enough project that restarting the LA step won't cost you much time. If neither of those work, post the log file, which may contain the specific error msieve is coming across.
