Test that solves a 2D Poisson equation for temperature in homogeneous media using finite differences. This examples shows a straight-forward way to hook an application to the ADIOS2 library for its IO.

1. read: illustrates the Read API that allows running the reader either as

   • post-mortem to read all output steps
   • in situ to read step by step as the writer outputs them

2. write: illustrates the Write API as well as has implementations of other IO libraries

   • adios 1.x
   • hdf5
   • phdf5

3. read_fileonly: illustrates reading all output steps at once (a single read statement) into a single contiguous memory block. This approach only works for post-mortem processing.
