speed-up x1.25 is really - need symmetry when calculating batch inversion

[Telariust]

Hi, dev brichard19!
Take a look at this program.
github.com/JeanLucPons/VanitySearch
It also computes the keys sequentially, but uses symmetry to calculate batch inversion.
After fix code (turned off unallowable symmetry of Y and endomorphism), I was convinced that it works +%25 faster than BitCrack.
You can really speed up your creation, just do the calculation of the pack from the center to the edges.

RANGE: 0xF00000000 - 0xA00000000 = 0x500000000 (21,474,836,480)

@Telariust From where we can get VanitySearch v1.15.2 ? :D

[sponnusa]

Hi, You can download it from the GitHub link. http://github.com/JeanLucPons/VanitySearch FYI, It supports only cuda devices. Doesn't work with opencl devices like AMD gpus. Releases section. Regards,

how did you calculate the range for the kangaroo 0000000000000000000000000000000000000000000000000000000A00000000 for this address 1CABDYTie48wXV93XJ4Bdk7MFSTyshTXxg or is it a search range for all addresses?
