2. Sections Version Inquiries, Starting MPI Processes, and MPI and Threads
on pages Version Inquiries, Starting MPI Processes, and MPI and Threads.
The routines MPI_INITIALIZED, MPI_FINALIZED,
MPI_QUERY_THREAD, MPI_IS_THREAD_MAIN,
MPI_GET_VERSION, and MPI_GET_LIBRARY_VERSION
are callable from threads without restriction (in the sense of
MPI_THREAD_MULTIPLE), irrespective of the actual level of thread support
provided, in the case where the implementation supports threads.
3. Section Window Creation on page Window Creation.
The same_disp_unit info key was added for use in RMA window creation routines.
4. Sections Data Access with Explicit Offsets and Data Access with Individual File Pointers
on pages Data Access with Explicit Offsets and Data Access with Individual File Pointers.
Added MPI_FILE_IREAD_AT_ALL, MPI_FILE_IWRITE_AT_ALL,
MPI_FILE_IREAD_ALL, and MPI_FILE_IWRITE_ALL
5. Sections Control Variables, Performance Variables, and Variable Categorization
on pages Control Variables, Performance Variables, and Variable Categorization.
Clarified that NULL parameters can be provided
in
MPI_T_{CVAR|PVAR|CATEGORY}_GET_INFO routines.
6. Sections Control Variables, Performance Variables, Variable Categorization, and Return Codes for the MPI Tool Information Interface
on pages Control Variables, Performance Variables, Variable Categorization, and Return Codes for the MPI Tool Information Interface.
New routines MPI_T_CVAR_GET_INDEX, MPI_T_PVAR_GET_INDEX,
MPI_T_CATEGORY_GET_INDEX, were added to support retrieving
indices of variables and categories.
The error codes MPI_T_ERR_INVALID and MPI_T_ERR_INVALID_NAME
were added to indicate invalid uses of the interface.
