12) 4.3.1
Definition of "host". I think this denotes the same thing
that I would call a "node [of a cluster]". (Sometimes I
might use "host", rightly or wrongly, to refer to a whole
cluster.) I suspect that your use of "host" is consistent
with language used by some (but perhaps not all) MPI implementations.
If "host" is defined in JSDL 1.0, I suggest referring
to that definition here to make things clearer. If it isn't,
then you should define it.
