Francesco,
We use modules (http://modules.sourceforge.net/) to manage 14 different
OpenMPI versions on the same cluster, along with their associated
applications. This is a nice way to establish dependancies between apps
and libs and keep things organized.
Good luck.

Is it possible to have two different compilations of openmpi on the same
machine (dual-opterons, Debian Linux etch)?
On that parallel computer sander.MPI (Amber9) and openmpi 1.2.3 have
both been compiled with Intel Fortran 9.1.036.
Now, I wish to install DOCK6 on this machine and I am advised that it
should be better compiled on GNU compilers. As to openmpi I could
install the Debian package, which is GNU compiled. Are conflicts between
the two installation foreseeable? Although I don't have experience with
DOCK, I suspect that certain procedures with DOCK call sander.MPI into
play.
I rule out the alternative of compiling Amber9 with GNU compilers, which
will run slower.
Thanks
