Was there any progress made with BSGS solver for CUDA meanwhile? I just stumbled over this old post and tried to use it, however I was not successful. I downloaded purebasic from the suggested link at the bottom of Etayson's Github repository, however the free version that is available for download on www.purebasic.com is a demo version which is limited to a few thousand lines of code and thus the loaded purebasic file will not get executed. OP said that we need PureBasic v5.31 but I cannot find this full version 5.31 on the webpage. Can anyone point me to a working download link for 5.31 for Linux x64, please?

Is BSGS solver useless meanwhile and there are some better tools that you would suggest? I am only aware of Keyhunts' BSGS mode which is executed in CPU threads. A CUDA version would be nice to test and hopefully get a higher rate.

@Etar, are you even reading this anymore? Maybe under a different username? If so, please reply.

I am trying to compile your program <bsgscudaussualHTchangeble1_7_3.pb> with PureBasic v5.31 under Linux. Unfortunately I do not succeed. At the first try I got this error message:

Code:

$ pbcompiler ./bsgscudaussualHTchangeble1_7_3.pb

This one was easy to fix, I just had to replace the backslash into a forward slash in line 2 of your program. I guess you were using Windows where folders are separated by the character '\' instead of '/' in Linux.

IncludeFile "lib/Curve64.pb"

But then after another try I get the error indicating that no cuda.lib was found. I searched for this file but wasn't able to find, even not under my CUDA installation in /usr/local/cuda* there is absolutely no such file on a linux system. Where do we find this file? I was able to find a similar file and I thought I give a try

Code:

cp /usr/local/cuda-11.8/targets/x86_64-linux/lib/stubs/libcuda.so ~/BSGS-cuda/lib/

then I replaced line 42 by:

Quote

Import "lib/libcuda.so"

but the compiler still fails, see here:

Code:

$ pbcompiler ./bsgscudaussualHTchangeble1_7_3.pb

If anyone else here is reading along and can help, I am of course also very grateful for helpful tips and recommendations. Any help appreciated. Thank you

I tried to switch off PIE with code below at start and you can compile and build executable for Linux, but running that code ended with "Illegal instruction (core dumped)".

Code:

Import "-no-pie"
endimport

Actually I am trying to debug it, however I am not very far with it. No success yet.
