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

SISAL

    (Streams and Iteration in a Single Assignment
   Language) A general-purpose single assignment functional
   programming language with strict semantics, automatic
   parallelisation and efficient arrays.  Outputs a dataflow
   graph in IF1 (Intermediary Form 1).  Derived from VAL,
   adds recursion and finite streams.  Pascal-like syntax.
   Designed to be a common high-level language for numerical
   programs on a variety of multiprocessors.

   Implementations exist for Cray X-MP, Cray Y-MP, Cray-2,
   Sequent, Encore Alliant, dataflow architectures,
   transputers and systolic arrays.

   Defined in 1983 by James McGraw et al, Manchester
   University, Lawrence Livermore National Laboratory,
   Colorado State University and DEC.  Revised in 1985.
   First compiled implementation in 1986.  Performance superior
   to C and competitive with Fortran, combined with efficient
   and automatic parallelisation.

   Not to be confused with SASL.

   David C. Cann has written an Optimising SISAL Compiler
   (ftp://sisal.llnl.gov/pub/sisal) (OSC) which attempts to make
   efficient use of parallel processors such as Crays.
