File interoperability

For information about the following file interoperability topics, see IBM Parallel Environment for AIX: MPI Subroutine Reference and the MPI-2 Standard:

• Datatypes (MPI_FILE_GET_TYPE_EXTENT)
• External data representation (external32)
• User-defined data representations (MPI_REGISTER_DATAREP)
  • Extent callback
  • Datarep conversion functions
• Matching data representations

For information about the following topics, see the MPI-2 Standard:

• Consistency and semantics
  • File consistency
  • Random access versus sequential files
  • Progress
  • Collective file operations
  • Type matching
  • Miscellaneous clarifications
  • MPI_Offset Type
  • Logical versus physical file layout
  • File size
  • Examples: asynchronous I/O
• I/O error handling
• I/O error classes
• Examples: double buffering with split collective I/O, subarray filetype constructor
