From the DB? Just go to the downloads tab, select Batch of Primo-input files, select your PRP size (digits) and number of files. This gives you a zip file containing *.in files with the PRPs to test. Unzip them in your Primo work directory and turn Primo loose on them. When done, zip up the *.out files and upload them to the DB, presto, you're done!

I'll try 470 for now

Now at work with Primo.

Edit: How many files should I take? Is 10 the default?

10 files at 500 digits took ~ 20min, so you might want to take a bigger batch.

I put 470 in the "Start with digits" field. I guess the DB will trigger automatically the number of digits following its needs... 1559 bits should be about 500 digits.

I got 50, will d/l more after lunch.

Funny!

If there are not enough composites with 470 digits, it will continue with 471 , 472 etc.. so keep this in mind when reserving.

At the moment there are 73 prp's with 470 digits. If you download 100 numbers you'll be duplicating work with someone who starts at 471

I simple download 500 prp's and run the following batch file to put all the prp's with length %1 in a separate directory.

Code:

@Echo off
md .\batches\%1
grep -l "%1 dig" .\batches\*.in | xargs -n1 -i mv {} .\batches\%1

to avaoid dupplication, i'll take 475 (156 numbers)

Done and uploaded.

don't forget there might be 'newly' discovered PRP that are lower than the current '470' digit long one
