%X Helios is an Operating System designed to exploit highly
   distributed systems. The central goal of such a distributed
   system, is not only to provide increased fault tolerance,
   but also increased performance. This necessitates adequate
   support for parallelism at the application level. It is
   proposed that instead of extending an existing language, or
   producing a completely new language, parallelism can be
   defined at the distribution phase. A high level Component
   Distribution Language has been designed, which allows simple
   sequential components to be combined by simple parallel
   constructors to form more complex parallel structures. The
   implementation language is irrelevant thus providing
   consistent support for standard sequential languages in a
   distributed environment.
