m_adios2_io Module

This module contains ADIOS2 (ADaptable Input Output System version 2) operations for reading and writing data. ADIOS2 transports data as groups of self-describing variables and attributes across different media types (e.g., files, memory, network). ADIOS2 APIs are based on: - MPI (although non-MPI serial code is also supported) - Deferred/prefetch/grouped variables transport mode by default - Engine abstraction for reusing the APIs for different transport modes
