This took roughly 220hr to solve on a 6-core i7 otherwise engaged with 2 threads of sieving or ECM tasks. It looks like 33LP is producing matrices a bit bigger than 32LP on similar-sized tasks on the 14e queue. I may be trading 15% faster sieving for 10% slower matrix-solving by using 33LP. That's an improvement in total computation required for a factorization, but an increase in wall-clock time. |
