The Adaptable Input Output System version 2 (ADIOS2) is is developed as part of the United States Department of Energy's Exascale Computing Project. It is a framework for scientific data I/O to publish and subscribe to data when and where required.
...
MPI Although ADIOS2 is MPI-based, it can also be used in non-MPI serial code.
Data Groups ADIOS2 favors a deferred/prefetch/grouped variables transport mode by default to maximize data-per-request ratios. Sync mode, one variable at a time, is treated as the special case.
Data Steps ADIOS2 follows the actual production/consumption of data using an I/O “steps” abstraction removing the need to manage extra indexing information.
Data Engines ADIOS2 Engine abstraction allows for reusing the APIs for different transport modes removing the need for drastic code changes.
