Dear Community,
I need advise to get openmpi to work using lam. For testing I installed it on two machines running opensuse10.3 (both atholon 64) connected via ethernet. I then try to run a test script "hello.x" with the following commands:
jus_at_cusp:~/Code/Spielwiese/Mpi> make hello
mpicc hello.c -o hello.x
jus_at_cusp:~/Code/Spielwiese/Mpi> lamboot mfile
LAM 7.1.4/MPI 2 C++/ROMIO - Indiana University
Enter passphrase for key '/cusp/jus/.ssh/id_rsa':
Enter passphrase for key '/cusp/jus/.ssh/id_rsa':
jus_at_cusp:~/Code/Spielwiese/Mpi> lamnodes
n0 cusp:1:origin,this_node
n1 neutrino.stat.physik.uni-potsdam.de:1:
jus_at_cusp:~/Code/Spielwiese/Mpi> mpirun -np 2 hello.x
Process 0 on cusp out of 2
Process 1 on cusp out of 2
The jobs are thus wrapped only on the node "cusp", not on both. I have no clue why this is.
Thanks, Justus
