Abstract

EARLY DESIRE is a new, floating-point equation- language simulation system for Digital Equipment (DEC) PDP-11 and LSI-11 minicomputers. It combines

(1) An interpreted job-control language for inter active program entry, editing, file operations, and multi-run experiments

(2) An efficient, very fast compiler for the time- critical dynamic segment equation solution

(3) Precompiled FORTRAN library routines for dif ferent integration-rule overlays.

EARLY DESIRE needs no external compiler or linker. It executes directly on a RUN command at a speed 1.3 to 4 times faster than DEC RT-11 FORTRAN. Future DESIRE systems will run on 32-bit computers and will employ attached array processors as execution processors.
