Hi all,
I want to activate GPU support in the Debian package for the BART toolbox, but I am not sure what is the best way to approach this. There may be several options: We can provide an additional package which can be installed alternatively, e.g. bart-gpu and which provides a CUDA-enabled binary and conflicts with the regular package. But I wonder whether this would make all bart packages non-free? Or do we need two separate source packages? Maybe there is a way to compile and link against CUDA with requiring the presence of the dynamic library of run-time. We could then dlopen the library at run-time if it is present. But the compilation would then still depend on a non-free package. We could try to move GPU backend into a module which can be loaded at run-time and which is then packaged separately. But this would require some development effort. Maybe you have some recommendations? Or you can recommend a package to look at as an example? Best, Martin
