The Free On-line Dictionary of Computing (30 December 2018):

MultiLisp

    A parallel extension of Scheme with explicit
   concurrency.  The form (future X) immediately returns a
   "future", and creates a task to evaluate X.  When the
   evaluation is complete, the future is resolved to be the
   value.

   [Did MultiLisp use PVM as its intermediate language?]
