Hi,
I think the *precompiled* program you are using is causing the problem.
With a new installation of LAM/MPI please recompile your program and do
mpirun on the executable that forms.
It is very likely that the program you are running was compiled with some
other version of LAM/MPI and is not compatible now.
Hope this helps,
Nihar
