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.
Latest version: 12.0, SISAL 1.2.
