A TRANSLATOR-ORIENTED INTERMEDIATE COMPUTER LANGUAGE

Description: S>An intermediate language is described that was developed for the translation process for Algal programs and its requirements in terms of target language. The requirements made of the target language were that it be parenthesisfree, that it contain a minimum number of instruction types, and that it would simplify the translation process. The feasibility of this language as target language to simplify the machine translation process and the direct implementation of this language on a computer by means of suitable hardware is considered.

COMPILER INTO GEORGE ASSEMBLY ROUTINE

Description: This program of the GEORGE Assembly Routine (GAR) will accept Fortran- like statements from paper tape and create the GAR language program on tape. This includes the needed calls for common subroutines and the reservations for the named variables and temporaries. The original statements in Fortran are carried along as remarks. The GAR language program may then be processed in the usual way by the GEORGE Assembly Routine, giving machine-language code. The level of sophistication of the source language is roughly equal to that of Fortransit or SALT. (auth)

MATHEMATICS PANEL ANNUAL PROGRESS REPORT FOR PERIOD ENDING DECEMBER 31, 1960

Description: The construction of a translator to Oracle language from ALGOL, the international algebrnic language, is described. The use of functions other than polynomials, e.g., trigonometnic fu nctions, as a basis for numerical quadrature in solving differential equations is considered. Functions satisfying a recursion in such a way that the stability of the computation is stabilized are evaluated, and matrices are studied with reference to localization of characteristic roots. Some problems in biology, medicine, health physics, and metallography requiring statistical analysis are described. Programming activities are described, including a program for analyzing the transmission data in neutron cross section determinations. A bnief summary of the Oracle operating experience and practice is given. (D.L.C.)

A Comparison of the IBM 370/168 MODEL 3 with the Amdahl 470V/6 and the IBM 370/195 Using Benchmarks

Description: As part of the studies preliminary to the acquisition of additional computing capability at Argonne National Laboratory, six groups of jobs were run on the IBM 370/195 at the Applied Mathematics Division of Argonne National Laboratory, on an Amdahl 470V/6 at the Amdahl manufacturing facilities in Sunnyvale, California, and on an IBM 370/168 MODEL 3 at the IBM Field Support Center in Gaithersburg, Maryland. This report compares the performance of the IBM 370/168 MOD 3 with that of the other two machines. Differences in machine configurations were minimized. The memory size of each machine was identical, the I/O configurations were as similar as possible, and the same versions of OS/MVT 21.7 and ASP 3.1 were used on all three machines. This allowed the comparison to be based on the relative performance of the three CPUs.

A Computer Program for Calculating One-Dimensional Hydrodynamic Flow: KO Code

Description: A computer program is described for the solution of shock, detonation, and spall problems for one-dimensional linear, cylindrical, or spherical hydrodynamic flow. The Flume option is used for calculating flow- through arbitrary cross sections. (R.J.S.)

GAMMA I. A GENERAL THEOREM-PROVING PROGRAM FOR THE IBM 704

Description: GAMMA I is a FORTRAN-compiled program for the IBM 704 Electronic Data- Processing Machine. It embodies a certain general, uniform procedure H of mathematical logic for seeking out a proof of any theorem within any mathematical theory which is given in formal axiomatic form. An extended discussion is provided of the underlying method and of the necessary background of mathematical logic. The program is described in detail. (M.C.G.)

A General 704 Service Library

Description: A unified set of input, output, and diagnostic routines for the Argonne IBM 704 digital computer is described. The library is designed to give maximum ease in programming the input and output functions required by a program. lt also provides for rapid execution of diagnostic and emergency dumps. (M.C.G.)

AN IBM-7090 SUBROUTINE PACKAGE FOR LAGRANGIAN INTERPOLATION

Description: A FORTRAN subroutine was writteni for the purpose of generating a table of data by Lagrangian interpolation in a smaller table of data. There are three options for the interpolation scheme: linear, semilog, and log-log. The number of points to be used in the Lagrangian interpolation is optional. This subroutine provides information for a table lookup, which is usually much less costly than direct computation. (auth)

AN ALGOL 60 SYNTAX CHECKER FOR THE IBM 7090 COMPUTER

Description: A syntax checker was designed based on the syntax of Algol as previously described. It was desirable to design the syntax checker as a set of mutually recursive processors tied together by building blocks which perform certain bookkeeping functions. Because of the recursive nature of the language and of the syntax checker, the problem of recovery after an error required much attention. A method was devised which permits most programs to be checked completely despite errors. The syntax checker was implemented for the IBM 7090 as a part of the SHARE ALGOL processor, and has operated very satisfactorily. (auth)

FUNDAMENTAL COMPONENTS OF THE "PACE" ANALOG COMPUTER

Description: The analog computer used in this installation was manufactured by Electronics Asscciates, Inc. The installation consists of two consoles and a test rack. Each console is made up of 56 operational amplifiers, 5 electronic multipliers, 5 diode function generators, 1 noise generator, 8 pot padders, 80 attenuators, and the recording equipment. It is possible to "slave" one console to the other for problems that require more equipment than is available on the one console. The test rack is provided for the purpose of checking the components without causing any loss of operating time on the consoles. (W.D.M.)
