-I read an article from acm's sigops vol. 28, number 4 this weekend, having the
-title:
-
- a brief survey of systems providing
- process or object migration facilities
- by Mark Nuttall
-
-I found it very instructive.
-
-I think process / object migration should be considered for HURD, too,
-and it's important to look at that before supporting / emulating
-UNIX's fork and inherited open file descriptors,
-because those features might get contradictory if not carefully designed.
-
-Regards esp. to the HURD folks

-Process migration is not a problem for the Hurd--it's a problem for
-Mach. If a Mach task can be correctly migrated, then there is no
-problem.
-
-However, I want to do more than that with the Hurd; I want to have a
-collection of machines (I think I'll call it a ``Collective'') appear
-as a single machine. (Shades of amoeba here.)
-
-This is the first (and harder) task--making a single global space of
-pids, etc.
-
-The second (and easier) task is migration.

-
-Great! (I think we talked about this before...)
-
- This is the first (and harder) task--making a single global space of

-
-This point seems somewhat questionable. Maybe we're thinking about
-the same idea in the long run, but I don't think that migrating
-data about the whole system around would be very useful...
-I mean, you still want a very large collective to work, though it
-could well get bogged down by the details of huge amounts of info.
-
-I think a more optimal (and more practical) approach would be to:
-
-Create a model of a "user context" that keeps track across multiple
-machines what resources and programs a user is working with.
-
-There would also be publically known "services" that would be advertised.
-Note that "advertising" is a specific activity that is usually not
-performed, unless one desires to do so.
-
-Anything else is really of little or no concern except to a local group of
-machines (for resource-balancing issues). So machines would automatically
-keep in touch with other nearby machines, but it would be modulated by
-distance.
-
-The big question is this (and for that matter, other models) is that
-of authentication in some kind of reasonably reliable manner.
-
- The second (and easier) task is migration.
-
-Agreed.
