LLR GPU application
 
Hi,


I'm wondering if the GPU LLR software found at Jean Penne's [URL="http://jpenne.free.fr/index2.html"]website[/URL] is in progress or of any use.




I've installed [URL="https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=2004&target_type=runfilelocal"]CUDA Toolkit 11.1[/URL] (deb local) for Linux Ubuntu 20.04. After that I tried to compile the CUDA version of LLR:



(llrcuda Version 3.8.1 complete source, presently only for Linux build)



[CODE]~/llrcuda381src$ make
/usr/local/cuda/bin/nvcc -g -O -I/usr/local/cuda/include -I. -Wno-deprecated-gpu-targets lprime.cu -c
nvcc fatal : '-I/usr/local/cuda/include': expected a number
make: *** [Makefile:11: lprime.o] Error 1
[/CODE]
There's also no readme which came along with the download so now I'm stuck on what I should do.



Thanks for help.

The optimization option, [B]-O[/B], is causing the error (it's no longer legal after CUDA 10). Try using [B]-O3[/B].
