Jarod,

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

Start Batch

Also the reservation should be on this thread [URL]http://www.mersenneforum.org/showthread.php?t=20023&page=21[/URL] instead.

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)

Trying to start GW_10_239
 
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.

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

All on one line in the fb file

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.
