CUDALucas 2.05.1 is posted to [URL="https://sourceforge.net/projects/cudalucas/files/"]sourceforge[/URL]. An error was discovered in the display output if ReportIterations=100 or 50 or 10. The error only caused the display 'Error' to stay at .25000. Actual results were not affected. I uploaded all windows versions as one file this time. You still need the .ini file.

If anything else is found, let us know.

Nice job!

Thanks. I was able to use the benchmark pages at [url]http://www.mersenne.ca/cudalucas.php[/url] to pick out a couple of inexpensive cards, and have *finally* got mfactc up and running under Linux Mint (circumventing Nouveaux got to be a real saga in itself). Unfortunately ... when I try running CUDALucas on the same system I get the error message "no such file or folder" !! I can see the file with ls -lt and yes I do own it and have permission to read, write, and execute it. I can move/rename it, compress it, etc., but if I type the file name to run it as a command, I get "no such". If I type ./CUDA*64 the system even parses/expands the filename correctly, but still returns "no such file" !

Its probably some silly thing you are overlooking. Some thoughts: Where did you extract the binaries to? What does the ./CUDA*64 expand to?

It may be a sys message trying ot tell you that it tries to open a library which is not found. Do you have it? IIRC mfactx needs only the runtime (cudart) but cudaLucas needs also FFT lib (cufft) (so you will need both libs). Try getting the right one for your system and put it in the same folder.

Is it a binary file or a script? Please post output from:
file "filename"
ls -l "filename
(in both commands replace "filename" with the name of the file).
And output from trying to run it.

I have a problem, when I run CUDALucas 1.2b with GTX 570 it runs fine for like ~30000 iterations and then my screen freezes. CUDALucas throws me the following error:
[CODE]CUDALucas.cu(695) : cudaSafeCall() Runtime API error 6: the launch timed out and was terminated.[/CODE]
Also, in the system tray I have the following message:
[CODE]Display driver NVIDIA Windows Kernel Mode Driver, Version 344.75 stopped responding and has successfully recovered.[/CODE]
I haven't overclocked my GPU. I am using Windows 8.1 x64. I am running CUDALucas as following:
[CODE]CUDALucas-2.03-cuda4.0-sm_20-x86-64.exe -t -c 1000 71050117[/CODE]

Hello,

Please download the newest version from [URL="https://sourceforge.net/projects/cudalucas/"]here[/URL]. Once you have read thru the README and gotten setup, let us know if you're still having a problem.

Thanks, getting the newest version with CUDA 6.5 fixed the problem.

I just downloaded CUDALuca 2.05 for Linux (i.e. the multile executable folder) from sourceforge, but when I try to run it I get:

(file or directory not present)

Any hints?

It is strange to me to have a file ending with *, but try with the star at the end. :smile:
