Hi all
My problem is the following I am trying to run a simple mpi code using
IMPI support. I installed lam 7.2b1r10223 because I found on your
mailing list that there were mistakes related with impi on lam 7.1.1
version.
Once installed I downloaded the impi server v1.3 and all tests were
fine. But the problem comes when I try to run a simple hello world
code.
First I run the server
./impi_server -v -server 1 -p 8000
Output
****************************
Authentication not specified on command line.
Checking environment variables.
IMPI_AUTH_NONE enabled.
server_auths[0] = 0
IMPI server version 0 started on host komolongma.ece.uprm.edu
IMPI server listening on port 8000 for 1 connection(s).
xxx.xxx.xxx.x:8000
IMPI server: Entering main server loop.
Then I the client
impirun -client 0 xxx.xxx.xxx.x:8000 -np 2 hello
But then the client do not prompt any output and looks like it is not
doing anything. The server did not prompt any acknowledge at all of
what is happening. So I kill the client and the output is the
following
Output
****************************
MPI_Recv: process in local group is dead (rank 2, comm 12)
Rank (0, MPI_COMM_WORLD): Call stack within LAM:
Rank (0, MPI_COMM_WORLD): - MPI_Recv()
Rank (0, MPI_COMM_WORLD): - MPI_Allreduce()
Rank (0, MPI_COMM_WORLD): - MPI_Comm_split()
Rank (0, MPI_COMM_WORLD): - MPI_Comm_split()
Rank (0, MPI_COMM_WORLD): - MPI_Intercomm_merge()
Rank (0, MPI_COMM_WORLD): - MPI_Init()
Rank (0, MPI_COMM_WORLD): - main()
-----------------------------------------------------------------------------
One of the processes started by mpirun has exited with a nonzero exit
code. This typically indicates that the process finished in error.
If your process did not finish in error, be sure to include a "return
0" or "exit(0)" in your C code before exiting the application.
PID 4527 failed on node n0 (10.1.1.1) due to signal 15.
-----------------------------------------------------------------------------
And the code is the following
#include <stdio.h>
#include "mpi.h"
int main (int argc, char *argv[])
{
int id, np;
char name[MPI_MAX_PROCESSOR_NAME];
int namelen;
int i;
MPI_Init (&argc, &argv);
MPI_Comm_size (MPI_COMM_WORLD, &np);
MPI_Comm_rank (MPI_COMM_WORLD, &id);
MPI_Get_processor_name (name, &namelen);
printf ("This is Process %2d out of %2d running on host", id, np);
MPI_Finalize ();
return (0);
}
Is there anyone who can help with this?
Thanks in advance.
