sisal n. 西沙爾草[龍舌蘭的一種] 西沙爾草[龍舌蘭的一種] sisal n 1: a plant fiber used for making rope [ synonym: { sisal}, { sisal hemp}] 2: Mexican or West Indian plant with large fleshy leaves yielding a stiff fiber used in e. g. rope [ synonym: { sisal}, { Agave sisalana}] (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.
