چکیده

REC (Regular Expression Compiler) is a concise programming language which allows students to write programs without knowledge of the complicated syntax of languages like FORTRAN and ALGOL. The language is recursive and contains only four elements for control. This paper describes an interpreter of REC written in FORTRAN.

Matrix Computations in Basic on a Microcomputer

We consider the efficient implementation of matrix computations in interpreted Basic on a microcomputer. Linear equations routines SGEFA and SGESL from the LINPACK library of Fortran programs are translated into Basic and run on four microcomputers: the Commodore 64, the Amstrad CPC 464, the BBC Microcomputer, and the BBC with a Z-80 second processor. The computational cost of the routines is f...

Lex ! A Lexical Analyzer Generator

Lex helps write programs whose control flow is directed by instances of regular expressions in the input stream. It is well suited for editor-script type transformations and for segmenting input in preparation for a parsing routine. Lex source is a table of regular expressions and corresponding program fragments. The table is translated to a program which reads an input stream, copying it to an...

Program RCG MOD11 Calculation of Atomic Energy Levels and Spectra

RCG is a FORTRAN77 program initially coded (1964-65) on the IBM 7030 (”Stretch”), and subsequently modified (with addition of many new features and options) to run on other IBM, CDC, and CRAY mainframes, various VAXs and MicroVAXs, SUN and IBM RISC workstations, and finally Macintosh Centris 650 computers (68040 microprocessor with built-in floating-point processor and using the Language System...

Evaluating the Performance of Software Distributed Shared Memory as a Target for Parallelizing Compilers

In this paper, we evaluate the use of software distributed shared memory (DSM) on a message passing machine as the target for a parallelizing compiler. We compare this approach to compiler-generated message passing, hand-coded software DSM, and hand-coded message passing. For this comparison, we use six applications: four that are regular and two that are irregular. Our results are gathered on ...
