..Ty for your explanation, I can't pm u back because of messaging limits. So basically there is no way to combine really fast random hex generator to work with the calculation process? So all we can do is randomly get starting points and from there work in increments.
True, according to my knowledge after 1 year of research.

In fact, you want a gpu BrainFlayer. Everyone wants it)
Ryan refuses to write it because he is a WhiteHat.

If successful, it will be slower than sequentially calculating points.

heuristic calculate the hashrate for BrainFlayer cuda/opencl

BrainFlayer cpu sse
0,1 Mk/s - 1core i7-6820
8core - 4core real, 4core hyper-threading, so x6 instead x8
0,6 Mk/s - 8core i7-6820

VanityGen x64 opencl
60.7 Mk/s - gtx980
0,52 Mk/s - 8core i7-6820

60.7/0,52 = x116,7 (vg opencl gpu/cpu)

VanityGen x64 cpu sse
1,38 Mk/s - 8core i7-6820

1,38/0,52 = x2,6 (vg sse/opencl)

now if imagine
BrainFlayer opencl
0,6x(1/2,6) = 0,23 Mk/s - 8core i7-6820
0,23x116,7 = 26,8 Mk/s - gtx980

if
clBitCrack opencl
67.7 Mk/s - gtx980
cuBitCrack cuda
153.5 Mk/s - gtx980
241.3 Mk/s - gtx1070

153.5/67.7 = x2,26 (bc cuda/opencl)

then
BrainFlayer cuda
26,8x2,26 = 60,5 Mk/s  - gtx980
60,5x(241.3/153.5) = 94,9 Mk/s  - gtx1070
