This is the maximum that I can squeeze out of my 2080ti card:
16 pubkeys from JLP example solved in 1m 23s
Code:
NewFINDpubkey= (2375c86aa2a807fd50e4b1a2a65820244e704b8eabc8eb4dc0517393aff0c647, fad56264ae29d620205a68792091b64ae262bba359f8d013ce904d595e790ccf)

Used two hashtables:
first  for GPU without xpoint position, only xpoint 32bit + size htsz, totaly 32+29 = 61bit per xpoint
Second for host usage with xpoint position
Utilized 9008Mb of GPU memory.


i optimized parameters and the key

i solved in 17 seconds

well can you please tune it for parallel search for pubs , i undertand speed will drop but its still worth to try .. can you?
