io adios2 module

Extendable framework to support different schemas associated with MPI-parallel readers of ADIOS2 generated bp files containing several steps. This VTK Modules aims to serve as the backend to either Paraview (thin plugin ADIOS2Reader) and VisIT as part of the ADIOS2 Ecosystem.

• If a new feature, why is it useful and/or necessary? Users should be able to open bp files in Paraview, initially reusing VTK XML schemas for immediate applications. Schemas are required as the data model becomes more complex (number of variables, operations, unstructured mesh, etc.)

• Are there background references or documentation? ADIOS2 information: https://adios2.readthedocs.io/en/latest/ Example: https://github.com/pnorbert/adiosvm/tree/master/Tutorial/gray-scott

Looking for early feedback and direction on:

• Architecture, coding standards, license, etc.
• Testing

Currently working for VTK XML data formats stored as an attribute in a bp file:

• VTK image data : vti
• VTK unstructed data : vtu
