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 stack.

Thanks!
