Kusch, all, Thanks! I forgot about the excellent documentation. Itaru.

Hi Itaru, I am afraid that we do not have a comprehensive overview over code changes at the C++-level available. The most important parts there are probably the much simplified representation of nodes (no subnets any more) and the IO backend. #1338 recently also brought some significant changes to spike delivery by removing duplicity of transmission when one source has targets on multiple threads of a given MPI process.

Hi again, Hans, all, I take it back, my toolchain was just not built properly; besides, shared_ptr has been used in the base code prior to NEST-3. With the proper Clang 12.0.0 (via the Spack package manager) with OpenMP offloading support, I will try to offload the event delivery part using that programming model. Thanks, Itaru.
