Streams and Iteration in a Single Assignment Language.
A general-purpose single assignment functional programminglanguage 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
Implementations exist for Cray X-MP, Cray Y-MP, Cray-2,
Defined in 1983 by James McGraw et al, ManchesterUniversity, 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 (OSC) which attempts to make
efficient use of parallel processors such as Crays.
Latest version: 12.0, SISAL 1.2.
