Yes I have a 32GB machine that with 30.7 did P1 4x faster than these machines.

Pondering 30.8 with respect to this project.

George in 30.8 is working on determining the best B1/B2 for this new version.
Because Stage 2 is several times faster than it used to be the optimal B2 is a much higher multiple of B1.
This will...

I've added 20.3 and 20.5 to the ToDo list on Post #1

They are only TF'd to 73 bits but each range only needs 19 more factors.

If you choose to TF them to 74 they will likely clear.
If you choose to P-1 them with modest bounds they will also clear.

George can chime in but I would think 9.5G per worker seems like a lot for the new version.

If you are using GPU72 I think it should give you 21.9 or 21.8 or 21.7.
