HDF5 Engine in Adios2

[tybulut]

Hi,

I am looking for CPP examples of Adios2 with HDF5 Engine for the following use cases:

1. Write a local scalar variable (such as int16_t, float, ...) with no MPI
2. Write a local scalar variable (such as int16_t, float, ...) with collective-IO with MPI_COMM_WORLD
3. Write a local array variable (such as, std::vector) with no MPI
4. Write a local array variable (such as, std::vector) with collective-IO with MPI_COMM_WORLD
5. Read a local scalar variable (such as int16_t, float, ...) with no MPI
6. Read a local scalar variable (such as int16_t, float, ...) with collective-IO with MPI_COMM_WORLD
7. Read a local array variable (such as, std::vector) with no MPI
8. Read a local array variable (such as, std::vector) with collective-IO with MPI_COMM_WORLD

For example,

adios2::Variable<T> var = io.DefineVariable<T>(name, ...
engine.Put(var, value, ...

I found some unit-tests in adios2 source-code but the ones I found seemed to be example of global variables.

I was wondering if someone can help me! Thank you!
