Wait it is in dev
You need to add -gpu to enable

[virus-cyber]

Kangaroo.exe -t 0 -g 28,256 -gpu -gpuId 0 in.txt

[hamnaz]

you mean compile with make -gpu ?

[JeanLucPons]

no like virus said
for compile as usual in my other projects:
make ccap=yourccap gpu=1 all

[hamnaz]

i will sugguest you, always mark 2 section in readme

1. compile
   method of compile commands
2. run
   methode of run commands

it will help new and old users to always read readme and follow
thankx

Yes I update the README asap :)

cpu ver
only cpu speed is 11.34 mkeys/s
gpu ver

Done: Total time 45s

[JeanLucPons]

That is not so bad for a very first release :)

[hamnaz]

by setting grid 64,128 now i am getting 50 Mkeys/s

[hamnaz]

i think next task is multiple pubkeys check :)

[JeanLucPons]

Yes I will optimize thing for multiple key.
There is a great optimization that can be done by resuing old points.

[djarumlights]

JLP at it again with the excellence!

Hi the question is how you choose range where to search keys? why you choose in the readme this Start:49DCCFD96DC5DF56487436F5A1B18C4F5D34F65DDB48CB5E0000000000000000
Stop :49DCCFD96DC5DF56487436F5A1B18C4F5D34F65DDB48CB5EFFFFFFFFFFFFFFFF
for you pubkeys? how you choose range? Thanks

And what does mean grid(-g) in parameter if i choose 368x368 it is points(million or what?)
I have rtx2080 as I know from the program I have 46x64 core I must multiply to 8 and received grid 386x512, right?

And why speed at start and after few hours reduce fo me from 1000m to now 300m ? It’s normal?
But without param -g the speed is stable
Thanks

[JeanLucPons]

@kpot87
I will write few words to explain this on the README today.

Hi! what does it mean "B" at the end?

[JeanLucPons]

It is the last B] of MB], line is not cleared, a printing bug ;)

[Shadow145-cpu]

Hi, Low speed with GTX1060 6GB
It is normal speed or something wrong?
