MPI_Session_get_pset_info(3) MPI MPI_Session_get_pset_info(3)
NAME
MPI_Session_get_pset_info - Get the info associated with the processes
set
SYNOPSIS
int MPI_Session_get_pset_info(MPI_Session session, const char *pset_name,
MPI_Info *info)
INPUT PARAMETERS
session
- session (handle)
pset_name
- name of process set (string)
OUTPUT PARAMETERS
info - info object containing information about the given process set
(handle)
THREAD AND INTERRUPT SAFETY
This routine is thread-safe. This means that this routine may be safely
used by multiple threads without the need for any user-provided thread
locks. However, the routine is not interrupt safe. Typically, this is
due to the use of memory allocation routines such as malloc or other non-
MPICH runtime routines that are themselves not interrupt-safe.
NOTES FOR FORTRAN
All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an
additional argument ierr at the end of the argument list. ierr is an
integer and has the same meaning as the return value of the routine in C.
In Fortran, MPI routines are subroutines, and are invoked with the call
statement.
All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in
Fortran.
ERRORS
All MPI routines (except MPI_Wtime and MPI_Wtick ) return an error value;
C routines as the value of the function and Fortran routines in the last
argument. Before the value is returned, the current MPI error handler is
called. By default, this error handler aborts the MPI job. The error
handler may be changed with MPI_Comm_set_errhandler (for communicators),
MPI_File_set_errhandler (for files), and MPI_Win_set_errhandler (for RMA
windows). The MPI-1 routine MPI_Errhandler_set may be used but its use
is deprecated. The predefined error handler MPI_ERRORS_RETURN may be
used to cause error values to be returned. Note that MPI does not
guarantee that an MPI program can continue past an error; however, MPI
implementations will attempt to continue whenever possible.
MPI_SUCCESS
- No error; MPI routine completed successfully.
MPI_ERR_ARG
- Invalid argument. Some argument is invalid and is not
identified by a specific error class (e.g., MPI_ERR_RANK ).
MPI_ERR_SESSION
- Invalid session handle
MPI_ERR_OTHER
- Other error; use MPI_Error_string to get more information about
this error code.
