Hi,
You can run multiple different programs in the same LAM universe by
using a schema file to describe their node assignment.
On a side note, if you are just beginning with mpi or LAM, I heartily
suggest you investigate Open-mpi instead. Lam is in maintenance mode
and all development has moved to other implementations. Open-MPI is the
successor to LAM and the user forum is quite active.

Subject: LAM: How to run two programs in the same time with mpi
Hello,
now I use lam 7.1.4 and MPI to run my program. It is no problem if I
let only a program run.
The problem is starting whenever I use another program from another
directory. The second
program will make the first one stop with an error written as
One of the process 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 code before exiting the
application.
PID 9025 failed on node n0 (127.0.0.1) with exit status 1
For the command that I let mpi run is
mpirun -np 4 ./my_program &
Do I need more option about this command or what should I do to run two
programs in a same time?
Please help me! Thanks in advance.
