Before embarking on huge P-1 bounds, consider using GMP-ECM or waiting for version 30.8.

George, see my problem: https://www.mersenneforum.org/showthread.php?t=27331
As if I used B2 maximum value then the task would end.

What bounds b1, b2 did it select or you specify? How much ram did you allow it? P-1 or something else?

I guess 30.8 will be ready soon?

b1=954000, b2=44734000, P-1, prime95 chose itself with 40GB allocated (think 40984mb actual). Thought it was ratio of stage 1 to 2 times that was mostly the important bit but will happily provide more detail in future

30.7 is now the official release. I'm not sure it is important enough to merit front page coverage.

The amount of P-1 being done by users running the PRP and GIMPS work preferences makes me throw in a vote for "yes." 30.7's significant P-1 improvements over 30.3 should create at least some boost to overall throughput even if most of the people reached by an announcement aren't doing P-1 full time.
