The method (band generation) remains the best way to achieve this end, and by throwing more than 1 process at the task, this can be done in a couple of days.
You will need:
- a band directory in which you will generate the band files, and which has the capacity to hold them (total is roughly 425Gb)
- a copy of sudoku.exe placed in that directory
There are 401 non-empty bands. These are numbered 1 to 416 (Bands 395, 397, 398, 400, 402, 403, 404, 406, 408, 409, 410, 412, 413, 414, 415 are all empty). I give below a 401-line BAT file that will do the job as a single process, and I will show below how to split it into a multi-process balanced-load job, and optionally how to consolidate the bands with small grid counts into larger ones.
A command for generating band 1 looks like this:
- Code: Select all
sudoku -gb1 -f%v -o Band001.txt
Inside a BAT file, that "%" needs to be replaced with "%%". Below you will find a complete batch file that builds the entire catalog. The job file has a comment on every line that gives you the actual grid count that you should get for that band. The first few lines are:
- Code: Select all

You might wish to sort the file by the grid counts (these start in col 43) so that you can verify the process is working, and also to create the illusion of rapid progress as it churns out the band files!
Sorting also makes it easier to organise a multi-process job with roughly balanced loads. Split the job N ways by separating it into, say, all bands with < 1,000,000 grids in one job, and the remaining bands split into roughly equal chunks of total grids.
