MPI_Startall function
Starts a collection of persistent requests.
Syntax
int MPIAPI MPI_Startall(
int count,
_Inout_count_(count) MPI_Request *array_of_requests
);
Parameters
count
Size of the request array.array_of_requests
Array of requests.
Return value
Returns MPI_SUCCESS on success. Otherwise, the return value is an error code.
In Fortran, the return value is stored in the IERROR parameter.
Fortran
MPI_STARTALL(COUNT, ARRAY_OF_REQUESTS, IERROR)
INTEGER COUNT, ARRAY_OF_REQUESTS(*), IERROR
Remarks
Unlike MPI_Waitall, MPI_Startall does not provide a mechanism for returning multiple errors nor pinpointing the request(s) involved. Futhermore, the behavior of MPI_Startall after an error occurs is not defined by the MPI standard. If well-defined error reporting and behavior are required, multiple calls to MPI_Start should be used instead.
