I would double check that you are using CUDA 11.7, as upgrading does not usually remove the old version by default. Depending on where you installed CUDA 11.7 to, you may need to run commands like these to use the new version:

export PATH=/usr/local/cuda/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
export LIBRARY_PATH=/usr/local/cuda/lib64${LIBRARY_PATH:+:${LIBRARY_PATH}}

You seem to use using the latest Ubuntu 22.04, so if the above does not work, it may help to use an older and more stable version of Ubuntu. I was using Ubuntu 20.04 on the VM. Another option would be to just build it on Google Colab.

from gpuowl.

What version of GCC and CUDA were you using? On Linux I was able to build it with these commands:

git clone https://github.com/preda/gpuowl.git
cd gpuowl
git checkout cuda
sed -i 's/g++ -O2/g++ -O3 -g -Wall/' Makefile
sed -i 's/-O2/-O3 -g --compiler-options=-Wall/' Makefile
make openowl
make cudaowl

and then run it like this:

echo '106928347' > worktodo.txt
./cudaowl

However, it is significantly slower than the GpuOwl master/v6 branches and even CUDALucas:

$ ./cudaowl

This was on the Tesla V100 GPU, so you could compare the above speed to the timings listed in #253.

can you give me your executable?

Regarding all those string errors, adding #include <string> near the top of the common.h file will fix this issue.

Regarding this error error: parameter packs not expanded with ‘...’, it looks like you would need to either upgrade to CUDA 11.6 or use an older version of GCC. See NVlabs/instant-ngp#119 for more information.

Unfortunately, I no longer have the executable. It was on a Google Cloud VM.
