Since you're just starting out, can you upgrade to open mpi?

Subject: LAM: Unix Errno: 14 Bad Address
Hi, I'm new in this list.
I'm developing a MPI application that uses math.h lib. My problem is
that when I compile my application, no error ocurrs, but when I run my
application with mpirun, I get this error:
It seems that some error has occurred during MPI_INIT. This will
cause your process to abort. These kinds of errors are usually
system-related, such as running out of disk space, running out of
memory, or something more serious such as data not being passed
between processes properly. That is, you should not be seeing this
error message; if you are, something is likely Very Wrong with your
system. :-(
Perhaps this Unix error message will help:
Unix errno: 14
Bad address

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.
This is how I'm compiling the application:
mpicc -Wall -g -O3 -c dist.c lib/*.c
mpicc -Wall -g -O3 -o dist *.o -lm
Also, I'm running the application like this:
mpirun -c 2 dist
I'm using Ubuntu 9.10, lam 7.1.2, gcc 4.4.1
I hope that someone can help me, I googled a lot but I've found no
solution to my problem.
Thanks in advance.
