Etar, you are a smart programmer. It’s really not that much to mod. I made some simple mods and increased speeds by at least 3x on most cards.

But hey, y’all can say what you want to. Water off my back.

Maybe I’ll make a video to compare how many DPs JLP’s stock Kangaroo can get in x amount of minutes and then compare that to mine. But even then, there would be doubters.

But we can do a test; a timed test. Someone can give me a range, say a 44 bit range and I will run it with my mod at DP 29, and post results. 44 bit range with DP 29 should yield 2^15 DPs in 38 minutes using 1 RTX 4090.
Substaction jmp distance from kangaroo position will give a doubling in the speed of finding  DP.
But will these additional points give a result?
If you found another solution, then well done. I only found this way.
I believe @ _Counselor implemented this method; he would know if it gave any significant speed up. But if I remember, I believe he said it did not.

That is not true, the programs that he did, can be improved a lot.
Some optimizations that give a few percent or even 10-20 maybe someone can improve.
But an optimization that gives an increase of 2 times is unlikely.

For example my BSGS version is almost times 3 times 9 times faster that the Original BSGS from JLP, that is almost 300% 900%

just saying...


edit

click for proof 🖼️

With the same RAM JLP did that range in 3 hours, i did it in 20 minutes that is 900% faster...

All programs from JLP are perfectly optimized and if it were possible to improve the result, then the author would definitely do it.

To "double the speed" there is only one solution.
This is to use not only the addition of the kangaroo jump, but also the subtraction.
This will not require many resources, but will double the number of tested points and thus the number of  distinguished points.
But it will also slow down the progress of all kangaroos.
Can this help, maybe, or maybe it will just overload the hash table with extra distinguished points.
With this modification also need to turn off the check for dead kangaroos, because a kangaroo hitting the same position that was left
after the subtraction does not mean that the kangaroo is following the trail of another kangaroo.
But as i said above, the author would have done it if it had worked.

Im agree with you! I just wanna know how much speed kangaroo have with 4090 in Stock WO powerlimit..May be I doing something wrong but my speed on 4090 nearly Tesla V100 32Gb  1420 MKey/sec speeds

 Perhaps you have a modified kangaroo? what settings did you use to achieve this speed?

Yes, I modified the Kangaroo code.
Then what's the point of talking about the speed of the modified program? I can also set a multiplier of 2 or 3 in the speed test section to get the speed that I would like to see...duddde
What's the point of talking or asking questions at all on here? It appears you are shady if you would set something you would like to see, just to report it...duddde
Shady's here is your proposal to mine for you a puzzle in pool with your "modified" super program with 4x speed)))

  Results of RTX4090 is something of beautiful ! But, what do you mean when you say 7.7 Gkey/s?

Because what I understand is that you anaylize and execute 7.7 Ghash/sec of ripemd160(sha256(publickeycompressed(privatekey)), is it right?

No, I wish we could get that speed, then #66 would be in reach!

Remember, in Kangaroo, we are looking for distinguished points of the x point. So to keep it simple, it’s publickey(privatekey) and check for x amount of trailing distinguished points (could be leading DPs as well).
The more complicated are the jumps but really it’s a set stride(s) that all Kangaroos follow…a path of sorts, until a wild one lands on a tame one.

The wilds require one extra calculation but it’s either one more step of adding or subtracting, based on your version of Kangaroo.


how much realy speed rtx 4090 Kangaroo?
Real speed was posted. 7.7 GKey/s, for a single RTX 4090.

I always like numbers!
First, what is this modified kangaroo program?
Verified that a 3090 gets 4.8G Key/s

This is not JeanLucPons version of Kangaroo
this have a lot of unnecessary checks that slow down the process.

The plain cuda version of secp256k1 and several optimize changes have this speed.

RTX 3070 with power limit 170w 2.4 GKey/s  GPU Ram Usage 3.5GB
RTX 3090 with power limit 350w 4.8 GKey/s  GPU Ram Usage 8.0GB

And one dedicated server for check
have 32GB RAM ( 8gb+ ram need for bloom filters )
~140Gb of nvme used for kvrocks storage for store 2^31.10 of DP32
or 35Gb if use DP34

ps4all. Possibly I'll find time for compare if you have dp's (or work file fromJeanLucPons Kangaroo ) for still determine 120 and check wild/tame and later
(in compared dp's included buyed from zielar)

But i rarely come here.
how can you compare that to the speed of a kangaroo? it's a different program

No, it looks like someone is using albert0sd's keyhunt program via CPU only.
