Hi all,
First, excuse my english, it isn't good :)
Well, I have 2 machines, one a Xeon with 2 cpu (64bit) and a Pentium
4 with only one cpu. At the 2 machines I have installed Ubuntu 8
Server and all packages to open-mpi and gromacs.
I use gromacs for my works
Ok, in the 2 machines, at my users folder, I have a file like this:
machine1 cpu=2
machine2
Machine1 is Xeon (192.168.0.10) and Machine2 is Pentium 4
(192.168.0.11)
My file /etc/hosts is configured too.
When I run mpiexec in machine2, I have like this:
mariojose@machine2:~/lam-mpi$ mpiexec -n 3 hostname
machine1
machine2
-----------------------------------------------------------------------------
It seems that [at least] one of the processes that was started with
mpirun did not invoke MPI_INIT before quitting (it is possible that
more than one process did not invoke MPI_INIT -- mpirun was only
notified of the first one, which was on node n0).
mpirun can *only* be used with MPI programs (i.e., programs that
invoke MPI_INIT and MPI_FINALIZE). You can use the "lamexec" program
to run non-MPI programs over the lambooted nodes.
-----------------------------------------------------------------------------
machine1
mpirun failed with exit status 252
When I run in machine1 I have like this:
mariojose@machine1:~/lam-mpi$ mpiexec -n 3 hostname
machine1
machine1
machine2

I don't know why I have this message. I think that is a error.
I try run with gromacs, if anybody use gromacs and can help me I
like very much :) .
mariojose@machine1:~/lam-mpi$ grompp -f run.mdp -p topol.top -c
pr.gro -o run.tpr
mariojose@machine1:~/mpiexec -n 3 mdrun -v -deffnm run
It's works Ok. I see that cpu of 2 machines woks in 100%. It look
well for me. But I have a error em I run mdrun_mpi that is a binary
to work in cluster.
mariojose@machine1:~/lam-mpi$ grompp -f run.mdp -p topol.top -c

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 15964 failed on node n0 (192.168.0.10) with exit status 1.

I don't know what is problem.
Anybody can help me ?
