                                                MOBILE OBJECT SYSTEMS:

SCOPE


The success of massively distributed systems has fuelled the search
for a programming paradigm that addresses issues of scale, efficiency
and security. Recently a number of new languages and systems that
support computation mobility have been developed. Within the
framework of object-oriented technology, mobile object systems are
groups of running objects that can move over heterogeneous networks,
carrying both code and execution state.


LANGUAGES vs NETWORK OPERATING SYSTEMS


Many of the environments for mobile object systems currently available
have come from the programming language and network
community. Languages such as Telescript, Extended Facile, Obliq and
Java have all been used to implement mobile computations. In each
case, an important part of the implementation was devoted to a
run-time system in charge of: (1) allowing multiple computations to
run concurrently, (2) protecting the host from the computations by
strict resource access control, (3) protecting computations from other
computations, (4) migrating computations. Most often, all of the
features are implemented anew, ignoring the services offered by
operating systems. The reason is partly because of the desire to be
OS-independent and partly because currently OS technology is felt to
be inadapted to the needs of mobile applications.


TOPICS


The goal of this workshop is to explore new directions in operating
systems as well as the synergy with mobile computations and
object-oriented programming languages. Thus we will identify needs of
mobile programs and how these can be met by the innovative operating
system designs. A non-exhaustive list of topics include:


        * Operating systems for mobile computations
        * Programming language support for mobility
        * Integration of programming languages and operating systems
        * Resource management techniques
        * Innovative scheduling strategies
        * Security mechanisms and policies for mobile computations
        * Portable intermediate representations
        * Linking issues
        * Communication mechanisms
        * Management of mobile object systems
        * Experience reports


IMPORTANT DATES
        April 5, 1997: submission deadline
          May 5, 1997: notification of acceptance
        June 5, 1997: final version of papers

SUBMISSIONS


Prospective authors are invited to submit an electronic PostScript
copy by e-mail to: ecoopws@cui.unige.ch The paper should be no more
than 15 pages in the Springer-Verlag format for Lecture Notes in
Computer Science. Short papers and position papers are welcome.
Papers that attempt to establish links between different approaches
and/or include expository or survey material, as well as presenting
original results, are welcome. Results should be clear and useful to
other practitioners in the field. Description of a new system should
include reproducible, useful results or lessons learned. Papers
coming from the mobile computations community should highlight
technical aspects and operating system requirements. Papers from the
operating systems community should address issues relevant to mobile
computations. All papers will be reviewed and electronic copies will
be linked to the Web page of the workshop. A subset of authors will
be invited to expand submissions for presentation at the workshop and
possible publication. To be considered for publication, papers must
be unpublished and not submitted for publication elsewhere.


FORMAT


The workshop will take place in the two days before the ECOOP'97
conference. The number of participants will be limited to 20 persons,
the selection will be based on the submitted material. The first day
of the workshop will be devoted to presentations of on-going work and
of state of the art systems. Discussions of the problem topics
submitted by the participants will take place on the second day.
Workshop attendees are expected to take an active part in the
discussions.
