Hardware, how long are you running your precomp for? You have a set # of DPs or a percentage? 2/3 ops?
@WanderingPhilospher
The goal is ~512GiB worth of precomputed points (@ 16bytes/point).
How much bytes do you have for x-coordinate and for distance?
For the whole distance in 109bit range we need 109/8 ~ 14 bytes. If you allocate lower space, you need to brute the remaining bytes/bits if the collision is found.
If you have 16 bytes space per point, so you should split somehow it between x-coordinate and distance.
Please see my previous comment. Only 8bytes of the x-coordinate is needed plus ~4bytes for lookup information.
