Galaxy is an Alpha VMS (V7.2 and higher) feature that allows multiple
SMP systems in the same box to share resources, sometimes in parallel,
sometimes sequentially.  For instance, shared memory global sections
can cross the boundary between 2 (or more) sets of SMP processors
each running their own copy of VMS.  N-1 of the processors in one
"instance" (SMP set) can move to another instance via drag-and-drop.

Regular discussions of how this is good, bad, or indifferent are
held in comp.os.vms (with a very active participant from Sun saying
it doesn't help).  From the Ada perspective, however, the programming
environment is so similar to normal VMS that the issue of "compiler
support" is close to nonexistent.
