You are referring to Process Transparency (which actually can be
implemented at the task, process, or thread level).  The leaders
in this kind of work are Locus Computing Corp. in Inglewood and
Freedomnet in North Carolina.  LCC's product, the Locus Operating
System, formed the basis for IBM Corp.'s Transparent Computing
Facility (TCF), which allowed for a distributed, heterogeneous,
transparent filesystem AND process system.  It was first implemented
back in the early 1980's on VAXen, Series 1's, and 370's.  The first
commericial product, AIX/370 and AIX/PS/2 (386) offer TCF.

(I used to work for Locus, but have no commerical interest currently).

For more information, contact IBM or Locus Computing - 213-670-6500,
and mention TCF.

As an aside, watching process execute with or without user knowledge
as to execution location, as well as watching processes migrate
while executing to other systems, is Neat.  Wanna run that
geological survey program?  Let /*fast*/ find the quickest site!
