hello guys, can someone tell me how to change DP modulo in this kangaro's version " https://github.com/JeanLucPons/Kangaroo "
i want to set it at  2^30

Will you be compiling yourself?


yes i use my GPU but the kangoros jump are small 2^20 is not enough so i asked how to change it in files so it jump 2^30
Are you searching in the 2^40 range? The avg jump size is determined by the rangePower. It's set to rangePower / 2 + 1.

It's in the Kangaroo.cpp file, around the 730s/740s lines (depending if you've made mods or the version you are using)

code:
Code:
void Kangaroo::CreateJumpTable() {

#ifdef USE_SYMMETRY
  int jumpBit = rangePower / 2;
#else
  int jumpBit = rangePower / 2 + 1;
#endif
