Offline Reconstruction on GPU

[satabios]

I've successfully built the dvs-reconstruction, and also I'm able to run offline_reconstruction on the CPU. At times when the .aer2 file is of a huge chunk it either runs out of memory or hangs the whole system. Due to which I was trying it to run it on GPU with the flag -g. My command looks like ./offline_reconstruction -f "event-based.aer2 file" -o "output_folder" -g The command throws an error:

terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::program_options::invalid_command_line_syntax> >' what(): the required argument for option '--gpu' is missing Aborted (core dumped)

offline_reconstruction only works with a GPU, so I'm not sure how you managed to run it with CPU alone. The --gpu switch only allows you to specify which GPU to use and therefore expects a number as additional input: e.g. --gpu 0
