I appreciate the detail in the writeup- for e.g. Bur who sees a future in test-sieving, that post is a nice place to start.
Here's the conclusion for Ryan:
Code:
tasks.lim0 = 500000000
tasks.lim1 = 800000000
tasks.lpb0 = 34
tasks.lpb1 = 35
tasks.sieve.mfb0 = 67
tasks.sieve.mfb1 = 102
tasks.sieve.ncurves0 = 25
tasks.sieve.ncurves1 = 21
tasks.I = 16
tasks.qmin = 250000000
tasks.sieve.qrange = 5000
tasks.sieve.adjust_strategy = 2
tasks.sieve.rels_wanted = 3000000000
If memory is plentiful, consider running A=32 for the first ~500M relations for the extra yield at small Q, and then changing down to I=16. That should help with the duplicate-relations rate, too- making it more likely to get 2G unique relations before Q=2000M.
