A serious application using MPI????
Hey friends,
I am very new to the world of Message Passing Interface(MP), and learning writing small programs with it on my personal cluster. I intend to do my final year project using MPI. Could you tell me what kind of an application one could develop which could be considered serious enough for a semester project?
Thanks for your time!!

Hi all,
I'm writing an MPI application, in which I handle failures and recover them. In order to do that, in case of one node failure, I would like to remove that node from the MPI_COMM_WORLD group and continue with the remaining nodes.
Does anybody know how I can do that?

1st,I'm a newbie.
I've written a mpi program to realize the parallel computing and encounter many problems.
1. When the computing scale is small, that means the communication time is short, just needs few minutes, such as 14 minutes or less. The program runs well and finished the jog.

mpi_status_f2c
MPI_Status_f2c(3) LAM/MPI MPI_Status_f2c(3)
NAME
MPI_Status_f2c - Convert a status from its Fortran representation to its C representation
SYNOPSIS
#include <mpi.h>
int
MPI_Status_f2c(MPI_Fint *f_status, MPI_Status *c_status)
INPUT PARAMETER
f_status
- Fortran status
OUTPUT PARAMETER
c_status
- C status
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
If an error occurs in an MPI function, the current MPI error handler is called to handle it. By default, this error handler aborts the MPI
job. The error handler may be changed with MPI_Errhandler_set ; the predefined error handler MPI_ERRORS_RETURN may be used to cause error
values to be returned (in C and Fortran; this error handler is less useful in with the C++ MPI bindings. The predefined error handler
MPI::ERRORS_THROW_EXCEPTIONS should be used in C++ if the error value needs to be recovered). Note that MPI does not guarantee that an MPI
program can continue past an error.
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. The C++ bindings for MPI do not return error values; instead, error values are communicated by throwing exceptions of
type MPI::Exception (but not by default). Exceptions are only thrown if the error value is not MPI::SUCCESS .
Note that if the MPI::ERRORS_RETURN handler is set in C++, while MPI functions will return upon an error, there will be no way to recover
what the actual error value was.
MPI_SUCCESS
- No error; MPI routine completed successfully.
