I offer my help if it's needed (as long as I can do it in PHP ) If this helps, this is a screenshot of the stats I keep for myself in Excel: http://www.jamesheinrich.com/temp/p-1.png edit: you can't put images in posts here? The one thing I don't track, but would like to, is the total number of exponents processed, and the ratio of no-factor vs found-factor. Another stat (that I don't track) could be the number of CPU-years spent factoring, and relate that to the number of CPU-years saved by found factors (hopefully time saved > time spent ) Histogram of found factors length: Code: 46 | 1 | * ... 25 | 1234 | ********* 24 | 2433 | **************** ... 100-blocks of P-1s is a good size for me; maybe you could put the jobs up in batches of 100s (as you've been doing) for people with a lot of machine time, but split one of the 100 blocks up into four 25-blocks so that people with less CPU time could each grab a small chunk.
