(ADaptive Input Output System v2) library. It acts as a translation layer
converting generic I/O calls from the session interface into specific calls
to the ADIOS2 API.
The adios2_reader_t and adios2_writer_t types defined here extend the
abstract base types from m_io_base and implement required procedures
This backend leverages several key features of the underlying ADIOS2 library
- engine abstraction - the same API can be used for different transport
methods (e.g. BP4, BP5, HDF5)
- Asynchronous I/O - by default ADIOS2 uses a deferred transport mode
which can improve performance by overlapping computation and I/O
- MPI integration - it is designed for large-scale paralle I/O and
integrates with MPI, though serial operation is also supported
All user interaction must go through m_io_session.
Nodes of different colours represent the following:
Solid arrows point from a submodule to the (sub)module which it is
descended from. Dashed arrows point from a module or program unit to
modules which it uses.
Where possible, edges connecting nodes are
given different colours to make them easier to distinguish in
large graphs.
