BOINC NFS sieving - NFS@Home

Jarod,

This is a windows bat example. In bold the unknowns.

Start Batch

start /low /min msieve.exe -i GW_3_513.ini -s GW_3_513.dat -nf GW_3_513.fb -v -nc "target_density=112" -t 4

Resume Batch

start /low /min msieve.exe -i GW_3_513.ini -s GW_3_513.dat -nf GW_3_513.fb -nc3 -ncr -v -t 4

Also the reservation should be on this thread http://www.mersenneforum.org/showthr...=20023&page=21 instead.

Thanks Carlos, apologies for trying to reserve a number in the wrong thread

Or less tedious so you don't have to change your .bat every time:
Rename numbertofactor.ini to worktodo.ini
Rename rest of the files to msieve(.dat .poly etc.)

Run with just msieve.exe -nc (and low priority/ thread options)

[Jarod]

When I try and start the number with the following command line the command line window opens saying next number. I am not using the target_density as I believe if you want to run it on low priority you do not need it.

 start /low /min msieve.exe -msieve.ini -s msieve.dat -nf msieve.fb -v -nc -t 8

I have named all the files in the folder appropriately to match the command line.

Looks like the flag is missing before msieve.ini.

Target_density is never required, but defaults to 70. Higher target densities produce smaller matrices, if filtering can produce a matrix.

Thanks VB, you were right I had missed the –i flag. Now when I double click to open the command it just closes with no out put. It appears that I am missing base file but I'm unsure what it means. From a log earlier in the day

Maybe there is an issue with the .DAT file? In regards to the line that says about the skew 1.00, size 0.000e+000, alpha 0.000, combined = 0.000e+000 rroots = 0

Looks like an issue with the msieve.fb file. What does it contain?

All on one line in the fb file

[debrouxl]

Make sure that the line endings in the .fb file on your computer are CRLF, just in case ?

The values of N don't match.
