Unfortunatelly I'm not really expert in this. I'm using 'Visual Studio 2019'.
I have finally succeded to comply vs-kangaroo-hybrid.exe by choosing 'Release' in configuration (before was 'Debug' by default), but without any aadditional settings. Just as it was.
Where do I put this settings "make gpu=1 ccap=20 all"?
Another question here. Runnigng test and found that script goes over 100% i.e. for #50:
Compute capability 2.0 and 3.0 Not supported.
This is normal, the program does not make accurate calculations. Set -p 0 or for bits 50 use cpu version.
Ok. Agree, that could be, but we are triying to test gpu usage, not a cpu )). And to test it quickly I choose lower number addresses in order to see if I will get a propper result in the end.
So far looks like somethis I did wrong:

Result received in ~ 6.5 minutes

Result received in ~ 4.5 minutes
What am I doing wrong? This are the time to spent by CPU.
Could you share you results for #50?
