MPI, short for Message Passing Interface, is a library that allows you to write parallel programs in Fortran77 or C. The library uses common operating system services to exchange information among the parallel processes it creates.
This method calls the error handler installed on a communicator.
int MPI_Comm_call_errhandler(
MPI_Comm comm,
int errorcode
);
comm
is a communicator object describing a group of processes. In many applications, various processes work together, and a communicator describes the processes that a routine initiates.
errorcode
is the error code supplied to the communicator’s error handler.
If unsuccessful, the function returns an error. The error, by default, aborts the MPI job.
MPI_SUCCESS
, which is the value returned upon successful termination of any MPI routine.MPI_ERR_COM
is returned.Free Resources
