This is the first production release of the ADIOS v2.x branch. At this point, all public APIs can be considered fairly stable. This also marks the official transition from ADIOS v1.x to v2.x, thus v1.x should now be considered deprecated.


Major additions from the previous v2.2 Beta release include:

  • Additional testing added reaching over 300 test covering both low level unit tests and higher level mini-app use-cases.
  • APIs for local array handling (each rank is an independent chunk of data instead of a smaller piece in a global index space)
  • The dissemination of per-rank write block information so a reader can know which pieces of a variable were written by which rank and optimize their read selection accordingly.
  • An extensive list of bug fixes.
