Maybe I should move this to [VTK](https://gitlab.kitware.com/vtk/vtk/-/issues)? Any thoughts?

> @jorgensd it's OK if it's here. I am trying to understand the request. You can read current datasets generated with M processes launching ParaView with any number of N...

Maybe I'm missing something basic in ADIOS2. How, from an adios2 perspective would I read in a `local`-array written in 3 blocks with 2 mpi processes (say in C++). As...

I.e. say we have this minimal script: ```c++ #include #include #include #include int main(int argc, char* argv[]) { MPI_Init(&argc, &argv); { std::filesystem::__cxx11::path filename = "test.bp"; adios2::ADIOS adios(MPI_COMM_WORLD); adios2::IO io =...

> @jorgensd in the adios2 API you set Variable block selection `SetBlockSelection` and local selections `SetSelection` for local arrays. The latter can be a function of your MPI rank to...

We should at least support float/double, as some use-cases read material parameters from the mesh . Ref: https://fenicsproject.discourse.group/t/i-o-from-xdmf-hdf5-files-in-dolfin-x/3122/48?u=dokken Where scalar data is actually a meshtag double object.

`trame` is now the new recommend way of using `pyvista` with jupyter. For using trame, we would have to add (according to the docs https://docs.pyvista.org/user-guide/jupyter/trame.html#trame-jupyter): ``` python3 -m pip install...

I'll revisit this soon (need to check the latest release of pyvista).

I've implemented a Python version of checkpointing at https://github.com/jorgensd/adios4dolfinx I will hopefully have time to make a C++ version in the next few weeks.
