[OMPI users] Error run mpiexec
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 - 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. - mpirun failed with exit status 252 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 pr.gro -o run.tpr -np 3 -sort -shuffle mariojose@machine1:~/lam-mpi$ mpiexec -n 3 mdrun_mpi -v -deffnm run NNODES=3, MYRANK=0, HOSTNAME=machine1 NNODES=3, MYRANK=2, HOSTNAME=machine1 NODEID=0 argc=4 NODEID=2 argc=4 NNODES=3, MYRANK=1, HOSTNAME=machine2 NODEID=1 argc=4 :-) G R O M A C S (-: Gyas ROwers Mature At Cryogenic Speed :-) VERSION 3.3.3 (-: Written by David van der Spoel, Erik Lindahl, Berk Hess, and others.
