[Beowulf] ANN: MorphMPI project (in alpha stage)

[Toon Knapen]

Dear all,

Some time ago there have been multiple discussions on an MPI ABI. 
Finally we concluded that we would be able to accomplish the same goal 
by putting a small layer on top of MPI (MorphMPI) that would make 
abstraction of the underlying MPI implementation. As usual, the solution 
is to add an extra level of abstraction ;-). Applications compiled 
against MorphMPI would be able to be relinked to any MPI implementation 
without having to be recompiled.

So finally I developed a small prototype of such a MorphMPI. Using this 
MorphMPI I was able to compile an application on an AMD-Opteron and 
launch it using mpich-ch_p4, mpichgm and the preinstalled mpich on a 
Cray XD1. To make sure it would not only work with several derivatives 
of mpich I also tested it successfully on an HP-UX using mpich-ch_p4 and 
HP-MPI (which is LAM based).

I uploaded my prototype to http://sourceforge.net/projects/morphmpi and 
you can find a (far too short) description at 
http://morphmpi.sourceforge.net/.

If there is any interest in the library I plan to make it more 
user-friendly and extend it to cover the full MPI-1.1 standard.
