[OMPI users] Adding new process to running job

[Juergen Kaiser]

Hi,

is it possible to add a new MPI process to a set of running MPI 
processes such that they can commnicate as usual? If so, how?


Thanks,
Jürgen

OpenMPI supports MPI-2, so, as far as I can tell, yes, you can do so
by using the dynamic process management functions defined by MPI-2.
Now this has to be done from the application code.

Take my words with a grain of salt, though, as I'm not an MPI guru (by far).
