NAME
MPI_Grequest_complete - Reports that a generalized request is complete. SYNTAX
C Syntax #include <mpi.h> int MPI_Grequest_complete(MPI_Request request) Fortran Syntax INCLUDE 'mpif.h' MPI_GREQUEST_COMPLETE(REQUEST, IERROR) INTEGER REQUEST, IERROR C++ Syntax #include <mpi.h> void MPI::Grequest::Complete() INPUT
/OUTPUT PARAMETER request Generalized request (handle). OUTPUT PARAMETER
IERROR Fortran only: Error status (integer). DESCRIPTION
MPI_Grequest_complete informs MPI that the operations represented by the generalized request request are complete. A call to MPI_Wait(request, status) will return, and a call to MPI_Test(request, flag, status) will return flag=true only after a call to MPI_Gre- quest_complete has declared that these operations are complete. MPI imposes no restrictions on the code executed by the callback functions. However, new nonblocking operations should be defined so that the general semantic rules about MPI calls such as MPI_Test, MPI_Request_free, or MPI_Cancel still hold. For example, all these calls are supposed to be local and nonblocking. Therefore, the callback functions query_fn, free_fn, or cancel_fn should invoke blocking MPI communi- cation calls only if the context is such that these calls are guaranteed to return in finite time. Once MPI_Cancel has been invoked, the canceled operation should complete in finite time, regardless of the state of other processes (the operation has acquired "local" seman- tics). It should either succeed or fail without side-effects. The user should guarantee these same properties for newly defined operations. ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ func- tions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to throw an MPI:Exception object. Before the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; 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. Open MPI 1.2 September 2006 MPI_Grequest_complete(3OpenMPI)

NAME
MPI_Add_error_code - Creates a new error code associated with errorclass SYNTAX
C Syntax #include <mpi.h> int MPI_Add_error_code(int errorclass, int *errorcode) Fortran Syntax INCLUDE 'mpif.h' MPI_ADD_ERROR_CODE(ERRORCLASS, ERRORCODE, IERROR) INTEGER ERRORCLASS, ERRORCODE, IERROR C++ Syntax #include <mpi.h> int MPI::Add_error_code(int errorclass, int* errorcode) INPUT PARAMETER
errorclass MPI error class (integer). OUTPUT PARAMETERS
errorcode Error code returned by an MPI routine or an MPI error class (integer). IERROR Fortran only: Error status (integer). DESCRIPTION
Creates a new error code associated with errorclass and returns its value in errorcode. NOTES
No function is provided to free error codes, as it is not expected that an application will create them in significant numbers. The value returned is always greater than or equal to MPI_ERR_LASTCODE. ERRORS
