So you see "cluster" as a narrow term, including single system image,
not including transparent [de|at]tachment of nodes, and all nodes
under common administratice authority; not encompassing "grid" which
is a larger collection with looser coupling.

Condor?  grid.

RSH realm? grid.

bproc? cluster.

MOSIX? both.

MPI/PVM? ?


Others see "cluster" as a wider term, including both, leaving us without
a term for the small, tightly coupled groups.

MOSIX? cluster.
Condor? wide cluster.
bproc? cluster.
RSH? cluster.
MPI/PVM? ?

I have been told, "Condor is not a clustering architecture."  I suppose
whoever said that thinks rsh is not a clustering architecture either.

Do we have authoritative definitions yet?

Who's in charge?
