[OMPI devel] heterogeneous support

[Jeff Squyres]

I just noticed that heterogeneous MPI support is enabled by default.   
Do we really want this?  Doesn't it add a little overhead (probably  
noticeable on shared memory)?

I'd be comfortable with users specifically having to enable  
heterogeneous support via configure and having [slightly] better out- 
of-the-box performance for the common (homogeneous) case.
