Hello,
Yes you are right. The GPU code should also be modified to return good distances.
Do not try to solve this puzzle, it will take years using a rendering farm !

Hello OP,
I'm expressing my gratitude for stepping in to clear out this matter. Obviously, it should be a good lesson for absolutely anyone to always take with a big grain of salt what some users are trying to convince people of their "guaranteed" truth.

For everybody else - make your own judgments always in everything. Most of the claims done in these forums are complete bogus, with no actual underlying rationale to cover it up. Start by grabbing a statistics fast course, don't expect to miraculously reduce space-time algorithmic complexities, unless you change the fundamental hypothesis some way. Otherwise the Universe will just slap you in the face, since it's rules don't work according to our (very bad) intuition and perception.

I was able to solve a 128 bit key using an unmodded version, but I obviously knew where the key was and could place the kangaroos in optimal positions.

128-1 = 127, so really in a 127 bit range, because the program subs start range from key or start range is greater than 0.

As I stated, always do your own tests. Most don’t even know what the work files contain because they have never extracted them and looked under the hood.

However, JLP is basing time to solve off of older GPUs, more than likely the V100. Which when ran with this program, he’s probably right. A V100 only gets 1,600 MKey/s with this program. With 512 V100s, at that speed, it would take 2 years to solve. But fast forward from the last time he worked on this program and now you have 2 newer generation cards. The 4090 is a beast. With 512 of them and a modded/different version of Kangaroo, I calculate it would take right at 163 days to solve.

So I advise everyone to do their own DD and take what ktimes says, with a grain of salt. I believe he is the one who was going to solve #66 with pencil and paper. He’ll always spout this and that, and everyone but him is dumb, but hasn’t provided any insight into anything, other than his owned perceived genius.
