[OMPI users] lammps MD code fails with Open MPI 1.3

I built a fresh version of lammps v29Jan09 against Open MPI 1.3 which in turn was built with Gnu compilers v4.2.4 on an Ubuntu 8.04 x86_64 box. This Open MPI build was able to generate usable binaries such as XHPL and NPB, but the lammps binary it generated was not usable. I tried it with a

[OMPI users] MPI-2 Supported on Open MPI 1.2.5?

Just a quick question... Does Open MPI 1.2.5 support most or all of the MPI-2 directives and features? I have a user who specified MVAPICH2 as he needs some features like extra task spawning, but I am trying to standardize on Open MPI compiled against Infiniband for my primary software
