Because it doesn't include IMPI -

If you insist on public domain, I'd choose lam because it does include
IMPI. But I vastly prefer vendor implementations, where they are available.
I use SGI's (IRIX) version that comes with the box, so to speak, the same with an
IBM SP2 (like gseaborg.nersc.gov). That's really why there was so much work put 
into creating a standard for interoperability, and so far implementations in 
LAM (public domain), HP/MPI for HP-UX, and MPI/Pro for Windows. See

As you can see, HP has its own fully supported version of MPI -

http://www.hp.com/rsn/mpi/product_info.html

which is what I would recommend on that platform (I used to have an HP
and I had HP's MPI, lam, and mpich on it). Vendor supported versions of MPI
are better and far easier to install and use, in my experience.
