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

Hi Itaru,

You can look the documentation of the lastest version and the guide of transition: https://nest-simulator.readthedocs.io/en/latest/guides/nest2_to_nest3/nest2_...

Have a good day,

Hi, Can someone point me to the summary of changes other than git log so I can understand better the changes introduced for the NEST-3 releases?

Thanks, Itaru. _______________________________________________ NEST Users mailing list -- users@nest-simulator.org To unsubscribe send an email to users-leave@nest-simulator.org

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.

Best, Hans Ekkehard

Hi again, It's great documentation for users, but I actually was looking for the C++ code developer's documentation, as I am trying to OpenMP offload the spike delivery part to the GPU, but currently, most of std:* aren't supported by the CUDA RTL that's where I am stumbling upon.

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.

Hans et al., I am not at all against using std::* functions where appropriate, but as of this writing, CUDA RTL has limited support for them so embedding OpenMP offload code that's to my understanding, the natural extension of the NEST base-code is extremely tough at this moment. Can we discuss this off-line with the developers in the near future?

Thanks, Itaru.
