== Bitcoin challenge transaction: ~1000 BTC total bounty to solvers! ==UPDATED==

[brainless]

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?

Which video card do you use? What options does the program run with?

gtx 460 and gtx 750

Could you share you results for #50?

Just when power is set 12 for bit 50, it turns out Hop_module 41 is 1 long jump 2 ^ 41 - it's too far and the range of selected points goes far from bit 50. Accordingly, the search time will be much longer. Also, when a large power - DP parity / DPmodule becomes less than 18, which leads to a large amount of data received from the video card and errors occur, wild and tame files grow quickly. Accordingly, it also affects negatively. The optimum size of the DPmodule is 22 - 24 of these values ​​should be selected power. And if DPmodule is large, then fewer selected points will be saved in files and search time will increase. Therefore, it is installed no more than 24.
+ the comparator starts the comparison once every half a minute. Therefore, such a total time.

All noted. Thanks. Will continue testing.
Those two results that I gave a screenshots were both with p=0. But the one with lesser time was tested with rekey=5000.

 As I understand it, you can’t leave links to other resources here? I saw a channel on Patreone called Bitcoin Riches, where they talk about a script that you can solve a puzzle. Can anyone tell me about this?

Please how can I solve that problem ?

I get the same error

seems like here is the error :GPUEngine: Kernel: no kernel image is available for execution on the device

pls print your complete command for execuation you run

Here is the command. I am using GPU Tesla P4 with CCap=70 as I see in wikipidia.
./vs-kangaroo-hybrid -v 1 -p 8 -bits 56 -gpu 0230210c23b1a047bc9bdbb13448e67deddc108946de6de639bcc75d47c0216b1b

remove in folder
rm -R obj
rm vs-kangaroo-hybrid

recompile
 from start with this command
make gpu=1 ccap=61 all
then run command as i mention with correction

2days before i see alek76 message in post, he said soon at github, today i see, his post deleted, maybe he chnage his mind, and his new mind maybe work better then old mind

Right. First you need to fix possible inaccuracies, then there is no time to do this on Github.
The comparator on python works faster than on c ++, when the file sizes are more than 50MB - have to choose a comparator. In general, the correct way is to do the aggregation of selected points in the sql database on the server. The program should send them as a client. I have no time and knowledge for this   I will soon post it as it is.

Already available https://github.com/alek76-2/vs-kangaroo-hybrid

Nice job.

Since the slowing down is due to the  comparator, I would suggest that you defer comparison after doing many thousand or more hops.

The comparator starts in a separate thread, so "slowing down" is possible only with a weak CPU. With the comparator disabled, the GPU speed is the same. I agree, you can change the startup frequency:

Code:

//int slp = pow2Wsqrt * 1000;
int slp = pow2Wsqrt * 10000;// Sleep x10 
printf("\n[+] Runing Comparator every: %d sec\n", slp / 1000);

Ok

What are you specifically asking about? What is random? Who broke? Which function?  Can becom a telepath
Your message https://bitcointalk.org/index.php?topic=5218972.msg54160563#msg54160563
That's right - you need to build the program yourself from the Github sources! Having looked at the code, all doubts and distrust disappear.
By downloading the Bitcrack program from various sources, you can fall into the tricks of scammers. It is more likely that the author will not embed the scam code in the program! Or is it trolling Bitcrack!

So is it possible to restore the program after it is closed? Because the tame and wild files are overwritten.  This will help:

in Vanity.cpp

Code:
if (TWRevers) {
   bool F2Upload = TWUpload();
   if (F2Upload) {
      printf("\n Upload tame.txt and wild.txt ");
   }
  }
  else {
   //ReWriteFiles();
  }

alek76, in your revised script, how do you select points to save? I mean what kind of algorythm do you use for points to be saved. You do not save every calculated point after wild/tame jump.
Do you store these points in files or in memory?

If after the jump the coordinate Point.X % DPmodule == 0 then add to atomicAdd. The length of the jump is taken from the table and is equal to dS [pw]. Where pw is equal Point.X % Hop_modulo. On the host, point X and distance are saved to files. Could make a save in memory and use the string vectors, then changed your mind ...

Ok, thank you.
If you understand, can you please also exaplain why do we need this DPmodule? Actually we reduce the places visited by kangaroos only to those which are multiliers of DPmodule.

I also askd the same question in "Science fair project...." topic but did nut receive the answer: https://bitcointalk.org/index.php?topic=5173445.msg52713073#msg52713073

Can you explain why do we need DPmodule and Hop_module, and how could we select their optimal values?

[MrFreeDragon]

Chapter 6. The xperimental results and evaluation. But here they use probabilityof a point being distinguished is 2 ^ 20. In another solution, a multiple of 2 ^ 29 was used.

There should be some logical explanation for DPmodule selection. 2^20 or 2^29 will not be the same depending on the private key bits length. I mean that 2^20 could be optimal for 110bits key, but not good for 150bits key. 2^20 is more than 1 million - so we use only x-coordinates with factor 2^20 for our collission comprator, but possibly skip earlier collisions.

DPmodule selection is something like the balancing between calculation power and saving/comparator power. Extreme example: if we select DPmodule = 1, we will save every jump, so we will need more storage space, and also the more stored places we have the harder work for comparator. From the other hand we will catch "the 1st meeting between wild and tame kangaroos". Selecting greater DPmodule we will have less saved points, easier work for comparator but we can skip the actual meeting (i.e. collision we are looking for) between wild and tame kangaroos.

alek76, Can you please examine this in more details and find the logical exaplanation why the DPmodule for x-coordinate is used and how to select the optimal value for this module based on bits length of the key (or other factor if required)

when i try 65 bits, i get segmention error. But if i drop the bits to 60 it works fine. I am using Geforce GTX 2070 with ccap 75. Any thoughts please?
